Detailed Description
The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.
Fig. 1 schematically illustrates an arrangement of coupled or multimode identification probing equipment according to an exemplary embodiment of the present disclosure. The detection equipment may be arranged as a stationary or mobile detection device at a port, customs, station or the like, or may be a hand-held or portable detection device in which the properties of the object to be inspected (e.g. a solid object such as plastic) can be screened on site.
As shown, the multimode identification detection apparatus 100 generally includes an excitation light source assembly 110, a detector assembly 120, an optical path assembly 130, a monitor assembly, and a processor 140. In addition, a carrier rack 150 for receiving or supporting the object sample 1 may be further provided, as shown in fig. 2. The excitation light source assembly is used for emitting excitation light for irradiating the object sample 1 to be detected in the field, and as will be understood by those skilled in the art, the excitation light for irradiating the sample for detection may have various forms, such as laser, infrared light, etc., depending on the detection mode; the excitation light source assembly may include an excitation light source capable of emitting excitation light of one or more wavelengths.
The detector assembly 120 is used to detect light generated by the interaction of the object sample 1 with excitation light (e.g., inelastic scattering, reflection, diffuse reflection, transmission, attenuated total reflection, absorption, etc.) in situ to obtain at least both molecular and atomic spectral data of the object sample; the detector assembly may include a detector capable of detecting light in one or more wavelength ranges.
Depending on the specific requirements of the detection mode, the optical path assembly 130 may be disposed between the excitation light source assembly 110 and the object sample 1 for guiding the excitation light from the excitation light source assembly 110 to the object sample 1, and disposed between the object sample 1 and the detector assembly 120 for guiding the light generated by the interaction between the object sample 1 and the excitation light to the detector assembly 120. As will be appreciated by those skilled in the art, the optical path components for directing light between the light source, sample and detector may include various suitable light directing/redirecting elements, including optical elements such as prisms, beam splitters, mirrors, lenses, filters, collimators, and the like, as are known to those skilled in the art, and will not be described in detail herein.
It will be appreciated that in performing sample detection, to obtain spectral data of the sample, the detection system or apparatus may further comprise a spectrometer (not shown) which may be used to collect a signal generated by the object sample under illumination by the excitation light (e.g. a signal from a detector) and generate spectral data indicative thereof, from which the composition of the object sample may be determined based on the spectral data. As an example, spectral data of an object sample generated by a spectrometer may be compared to spectral data of known substances or compositions to determine the composition of the object sample. Such comparison may be accomplished, for example, by a computer or processor.
In the multimode identification detection apparatus 100 provided according to the exemplary embodiment of the present disclosure, multispectral detection is performed in the field, for example, at least molecular spectral data and atomic spectral data of a sample to be detected are obtained in the field, and the molecular spectral data and the atomic spectral data are combined or coupled to screen or identify properties of the sample. For example, after receiving the molecular spectrum data and the atomic spectrum data of the sample, the processor 140 determines the composition of the detected object sample based on the received molecular spectrum data, determines the content of an element (such as a target element or an element desired to be detected, for example, a harmful element or a substance) in the object sample based on the received atomic spectrum data, and can determine whether the harmful element or the substance contained in the object sample exceeds the standard; illustratively, in some applications, harmful elements or substances including, but not limited to, lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls or polybrominated diphenyl ethers, and the like, may be used to determine whether a sample of an object, such as a solid object such as plastic, has suspicion of being waste (e.g., solid waste); for example, when it is determined that the content of the harmful substance in the object sample is out of the limit and the object sample is solid, it may be determined that the object sample has a suspicion of belonging to solid waste. For example, a sample that is screened to be determined to have a suspected waste may be sent to a more specialized laboratory for accurate detection determinations. It is understood that atomic spectrum data can be obtained by performing single or multiple elemental content measurements on a certain position of a sample, or by performing multiple elemental content measurements on different positions of the sample.
The coupled or multimode identification detection arrangement according to the invention can be based on the spectral detection mode, i.e. used independently in the spectral detection mode, or can be coupled or used in combination with other detection modes. For example, such detection equipment may also be equipped with a monitor or sensing device for monitoring the sample for abnormal odors and radiation doses. As shown in fig. 1, the detection apparatus 100 further comprises a monitor assembly (170, 180) for monitoring in situ abnormal odors and/or radiation doses (e.g., external radiation throughout the radiation dose) that have diffused or radiated from the object sample 1 itself to obtain odor data and/or radiation dose data of the object sample. The processor 140 may also receive monitored odor data and/or radiation dose data for the sample 1 from the monitor assembly and determine whether the odor emitted by the object sample is abnormal based on the received odor data and/or whether the radiation dose of the object sample is out of compliance based on the received radiation dose data, both in combination or coupled to screen or qualify the attributes of the sample. For example, the processor may determine that the object sample has a suspicion of belonging to solid waste when the dose of the object sample is determined to be out of compliance and the object sample is solid, and/or determine that the object sample has a suspicion of belonging to solid waste when the odor emitted by the object sample is determined to be abnormal and the object sample is solid.
Therefore, in the detection equipment, the multispectral fusion detection technology can be combined or combined with technologies such as radiation dose detection, abnormal odor detection and the like, and the substance identification can be better carried out on site. The anomalous odor data may include TVOC (total volatile organic) odor data emitted by a sample of the object, and the TVOC gas may include n-butanol, toluene, xylene, dimethylethanolamine, ethylene glycol, diethylene glycol monoethyl ether acetate, and the like. In some examples, as shown in fig. 1 and 2, the detection device includes a monitor or sensor 170 for monitoring in situ the diffusion or emission of an abnormal odor from the object sample itself, and/or a monitor or sensor 180 for monitoring in situ the radiation dose (e.g., external radiation through radiation dose) of the object sample. Monitor or sensor 170 and monitor or sensor 180 are positioned adjacent to sample 1 and in communication with processor 140; these monitors or sensors may be integrated into a single monitor assembly or may be provided separately.
In embodiments of the present disclosure, the obtained molecular spectral data may include inelastic scattering spectral data and/or absorption spectral data of the object sample, and the atomic spectral data may include fluorescence spectral data of the object sample, such as X-ray fluorescence spectral data (i.e., spectral data of fluorescence generated by the sample under X-ray excitation or illumination). The inelastic scattering spectrum has a spectrum with substance molecule vibration rotation energy level information, and components of the sample can be identified by comparing the spectrum with the spectrum information in the database; the absorption spectrum is generated by vibrational rotational absorption of the molecules of the substance, and the composition of the substance can also be determined by comparing the spectral information with spectra in a database. Illustratively, atomic spectrum information can be obtained through X-ray fluorescence spectroscopy, after a sample is irradiated by X-rays, outer electrons of atoms jump to holes to emit fluorescence, energy information and elements have a corresponding relation, and the target elements and the content thereof contained in the sample can be determined by comparing the radiated energy information with a standard energy spectrum curve.
As shown in fig. 2, the excitation light source assembly may include a first excitation light source 111 and a second excitation light source 112, the first excitation light source 111 may emit first excitation light for irradiating the object sample 1, and the second excitation light source 112 may emit second excitation light for irradiating the object sample 1; accordingly, the detector assembly includes a first detector 121 and a second detector 122, the first detector 121 is used for detecting the light generated by the interaction of the object sample 1 and the first excitation light to obtain the first molecular spectrum data of the object sample, and the second detector 122 is used for detecting the light generated by the interaction of the object sample 1 and the second excitation light to obtain the atomic spectrum data of the object sample. Illustratively, the first excitation light from the first excitation light source may comprise one of a monochromatic laser and infrared light for exciting the sample to produce light or radiation associated with a molecular spectrum, and the second excitation light from the second excitation light source may comprise X-rays or other suitable radiation for exciting the sample to produce light or radiation associated with an atomic spectrum, such as X-ray fluorescence. Thus, the obtained first molecular spectral data may comprise one of inelastic scattering spectral data and absorption spectral data of the object sample, while the atomic spectral data comprises X-ray fluorescence spectral data of the object sample.
In some embodiments, the composition of the substance may be identified using only the absorption spectrum or the inelastic scattering spectrum, for example, the absorption spectrum or the inelastic scattering spectrum of the sample is obtained above using a combination of the first excitation light source and the second detector. In other embodiments, both absorption and inelastic scattering spectra can be used to identify the components of a substance, which technically complement each other by reflecting different aspects of the substance and spectral properties of different principles, thus ensuring the reliability of the detection results. As shown in fig. 2, the excitation light source assembly may further include a third excitation light source 113 that emits third excitation light for illuminating the object sample 1, the third excitation light may include monochromatic laser light or infrared light for exciting the sample to generate light or radiation related to the molecular spectrum, and correspondingly the detector assembly further includes a third detector 123 for detecting light generated by the interaction of the object sample 1 and the third excitation light to obtain second molecular spectral data, such as absorption spectral data or inelastic scattering spectral data, of the object sample. For example, when one of the first detector and the third detector detects absorption spectrum data, the other of the first detector and the third detector detects inelastic scattering spectrum data, both of which are used for identification of sample components, the identification results are complementary to each other or mutually verified to improve the reliability of the detection results. In other examples, the first detector and the third detector are both used to detect inelastic scattering spectral data or both used to detect absorption spectra to provide redundant detection or, as described below, for compositional consistency analysis at different locations of the sample.
The optical path assembly may include a variety of light directing elements for directing excitation light from the excitation light source assembly to the object sample and directing light generated by interaction of the object sample with the excitation light to the detector assembly. As shown in fig. 2, the optical path components include a first sub-optical path component 131 and a second sub-optical path component 132, the first sub-optical path component 131 being arranged to direct the first excitation light from the first excitation light source 111 to the object sample 1 and to direct a desired portion of the light generated by the interaction of the object sample 1 with the first excitation light (e.g., a portion associated with the inelastic scattering spectrum or absorption spectrum of the sample) to the first detector 121, and the second sub-optical path component 132 being arranged to direct the second excitation light from the second excitation light source 112 to the object sample 1 and to direct a desired portion of the light generated by the interaction of the object sample 1 with the second excitation light (e.g., a portion associated with the atomic spectrum of the sample) to the second detector 122. Where the excitation light source assembly comprises the third excitation light source 113 and the detector assembly the third detector 123, the optical path assembly may accordingly also comprise a third sub-optical path assembly 133 arranged to direct third excitation light from the third excitation light source 113 to the object sample 1 and to direct a desired portion of the light produced by the interaction of the object sample 1 with the third excitation light, such as a portion associated with the inelastic scattering or absorption spectrum of the sample, to the third detector 123. The combination of the excitation light source, the sub-optical path assembly and the detector may be referred to as a spectral detection module.
Illustratively, each detector may detect inelastic scattered light, reflected light, diffuse reflected light, transmitted light, fluorescence, and the like, respectively, from the object sample. It will be appreciated that the detection regime may be selected based on the interaction of the excitation light with the object sample (e.g., reflection, diffuse reflection, scattering, transmission, attenuated total reflection, absorption, etc.), and the positioning or placement of the detector, optical path assembly, excitation light source relative to the sample may be adjusted based on the detection regime. For example, although the detector and excitation light source are shown on substantially the same side of the sample, this is merely illustrative and not restrictive and may be used to detect reflected or scattered light from the sample, and in the case of transmitted light from the sample, the detector and excitation light source may be on substantially opposite or different sides of the sample.
Although the excitation light source assembly, the detector assembly, and the optical path assembly are described and illustrated as examples, which respectively include corresponding, independent or separately arranged components, this is not restrictive, and in other embodiments, the excitation light source assembly, the sub-optical path assembly, and the detector may be respectively combined into the excitation light source assembly, the optical path assembly, and the detector assembly (as shown in fig. 1), and the excitation light source assembly, the detector assembly, or the optical path assembly may be an integrated device or an integrated assembly; for example, the excitation light source assembly may include a monolithic excitation light source, such as a laser, that emits corresponding excitation light as needed for detection, or a plurality of excitation light sources assembled together, which may be oriented identically or differently; likewise, the detector assembly (e.g., first, second, and third detectors 121, 122, and 123, respectively) may comprise a monolithic detector, the same or different portions of which may be used to receive or detect various forms of light or radiation from the object sample, or may comprise multiple detectors for detecting different forms of light or radiation, which may be assembled together or located on the same or different supports; further, the optical path assembly may comprise a single or multiple sets of optical elements for forming one or more optical paths, the optical elements of the respective optical paths may be at least partially common or independent of each other, and the optical element directing light from the light source to the sample and the optical element directing light from the sample to the detector may be the same or at least partially common or independent of each other. It will be appreciated that these arrangements may be set or adjusted as appropriate according to actual needs, as long as the molecular and atomic spectral data of the sample or article under test can be obtained in situ.
It will be understood that the excitation light sources, optical path components, and detectors described in this disclosure may be arranged as desired, and that the illumination points or illumination locations of the individual excitation light sources on the sample do not necessarily coincide. The sample may be tested at multiple areas or locations by relative motion between the sample, the excitation light source and/or the optical path components to improve the accuracy of the detection. In some examples, the excitation light source assembly or its excitation light source is capable of moving relative to the object sample to change the illumination position or spot position of the excitation light on the object sample; in other examples, the optical path component or optical elements therein can be moved relative to the object sample, or the optical path component, while fixedly positioned relative to the object sample, can controllably change the optical path of the excitation light to the object sample to change the illumination position or spot position of the excitation light on the object sample; in other examples, the various components of the detection equipment may be held stationary or stationary and the sample or a carrier rack carrying the sample is moved relative to the components of the detection equipment to change the illumination position or spot position of the excitation light on the object sample. Accordingly, the detection equipment may also be provided with means for driving such relative movements, which are able to be set or adjusted according to the actual needs.
In some embodiments of the present disclosure, consistency of the composition of the object sample, i.e., whether the composition or constituents at a plurality of different locations of the object sample are consistent, may also be determined based on the detection of the composition of the object sample, which may help determine whether the object sample is waste (e.g., solid waste). For example, when the processor determines that the components of the object sample at different positions are inconsistent, the object sample can be determined to have a suspicion of being waste (e.g., solid waste), screened to be determined to have a suspicion of being waste, and sent to a more specialized laboratory for accurate detection determination. Conversely, when it is determined that the components of the object sample at different positions are consistent and the contents of harmful or limited substances are not out of limits (e.g., are less than respective limits), it can be determined that the sample is not waste.
Illustratively, light generated by the interaction of the object sample with the excitation light at different locations may be detected to obtain molecular spectral data having multi-dimensional spectral information including spectral data respectively associated with components at different locations of the object sample, and the processor determines the components of the object sample at the different locations based on the multi-dimensional spectral information to determine the component uniformity of the object sample. It will be appreciated that the "multi-dimensional spectral information" herein may reflect or indicate the composition at different locations of the sample.
In some examples, the multi-dimensional spectral information may include inelastic scattering spectral information and absorption spectral information, which may be used to identify the components of the sample to be measured, respectively, and the light spots focused on the sample by the inelastic scattering excitation light and the light spots irradiated on the sample by the absorption spectrum are not completely coincident, which may represent component information obtained at different positions or areas of the sample, which may be used as a basis for determining the component consistency of the sample.
As an example, the multi-dimensional spectral information may comprise a combination of single or multiple inelastic scattering spectra obtained from single or multiple locations of the object sample and single or multiple absorption spectra obtained from other single or multiple locations of the object sample, which may be achieved using an arrangement such as that shown in fig. 2. For example, the first multi-dimensional spectrum may comprise a single inelastic scattering spectrum obtained by illuminating a first location of the object sample with monochromatic laser light and a single absorption spectrum obtained by illuminating a second location of the object sample with infrared light; in some examples, the second location may be different from or not completely coincident with the first location; the second multi-dimensional spectral information may include a plurality of inelastic scattering spectra obtained by irradiating a plurality of different positions of the object sample with the monochromatic laser light and a single absorption spectrum obtained by irradiating the object sample with infrared light (e.g., a single absorption spectrum obtained by irradiating other positions of the sample); the third multi-dimensional spectral information may include a single inelastic scattering spectrum obtained by illuminating a single location of the object sample with the monochromatic laser light and a plurality of absorption spectra obtained by illuminating a plurality of locations of the object sample with the infrared light (e.g., a plurality of absorption spectra obtained by illuminating a plurality of other locations different from the single location).
In other examples, the multi-dimensional spectral information of the molecular spectrum may also utilize only inelastic scattering spectra. For example, the multi-dimensional spectral information may also include a plurality of inelastic scattering spectra obtained by illuminating a plurality of different locations of the object sample with excitation light of the same wavelength or different wavelengths; illustratively, a sample can be excited by using certain excitation light of 532nm, 785nm, 830nm or 1064nm, inelastic scattering spectra are collected, and multidimensional spectral information is obtained by testing a plurality of sample positions; or exciting the sample by adopting laser with two or more wavelengths, testing one or more sample positions, and acquiring inelastic scattering spectra to obtain multi-dimensional spectral information. In the case of obtaining multi-dimensional spectral information of a sample only using inelastic scattering spectra, the multimode identification joint detection equipment may be provided with one spectral detection module for detecting inelastic scattering spectra, and a plurality of inelastic scattering spectra at a plurality of different positions of the sample may be obtained using the relative position between the spectral detection module and the sample; alternatively, the multimode identification union detection apparatus may be provided with two or more spectral detection modules, which may also be fixed or movable, for respectively detecting a plurality of inelastic scattering spectra at a plurality of different locations of the sample. The excitation wavelengths, optical paths, and detectors employed by the two or more inelastic scattering spectral detection modules employed may be the same or different.
In other examples, multidimensional information of molecular spectra may also utilize only absorption spectra. For example, the multi-dimensional spectral information may also include a plurality of absorption spectra obtained by irradiating a plurality of different positions of the object sample with infrared light of the same frequency band or different frequency bands; illustratively, excitation light of a certain frequency band within the range of 0.75-25 μm can be adopted to irradiate a sample, signals of the excitation light after the reflection, transmission or attenuated total reflection of the sample are collected, the absorption spectrum of the sample is obtained through the analysis of the collected signals, and multi-dimensional absorption spectrum information is obtained through the test of a plurality of sample positions; or the signals after sample reflection, transmission or attenuated total reflection are respectively collected after the sample is irradiated by light of the same frequency band or different frequency bands, and multi-dimensional absorption spectrum information is obtained by testing the position of a single sample or a plurality of samples. In the case of obtaining multi-dimensional spectral information of a sample only by using an absorption spectrum, the multi-mode identification combined detection equipment can be provided with a spectrum detection module for detecting the absorption spectrum, and a plurality of absorption spectra at a plurality of different positions of the sample can be obtained by using the relative position between the spectrum detection module and the sample; alternatively, the multimode identification union detection apparatus may be provided with two or more spectral detection modules, which may also be fixed or movable, for respectively detecting a plurality of absorption spectra at a plurality of different locations of the sample. The wavelength ranges, detection modes (reflection, transmission or attenuated total reflection) of excitation and detection of the two or more absorption spectrum detection modules employed may be the same or different.
In addition, the accuracy of component consistency judgment can be further improved by obtaining the multi-dimensional molecular spectrum information of a plurality of positions of the sample through a plurality of tests.
In addition, embodiments of the present disclosure also provide a multimode identification joint detection method, which can be implemented by using the multimode identification joint detection equipment described in any embodiment of the present disclosure, for example, and can perform coupled or multimode identification joint detection to realize rapid inspection of components and element contents of an article in the field. Fig. 3 illustrates a flow of a multimodal identification federated probing method according to an exemplary embodiment of the present disclosure. As shown, the method may include the steps of:
s1: emitting excitation light for irradiating an object sample to be detected in situ;
s2: obtaining molecular spectral data and atomic spectral data of an object sample;
s3: the method includes determining a composition of the object sample based on the molecular spectroscopy data, and determining a content of an element (such as a target element or an element desired to be detected, e.g., a harmful element or substance) in the object sample based on the atomic spectroscopy data.
For example, in step S1, excitation light for irradiating the object sample 1 to be detected may be emitted in the field by the excitation light source assembly 110.
Illustratively, in step S2, the excitation light may be directed to the object sample by the light path component 130, and the light generated by the interaction of the object sample and the excitation light may be directed to the detector component 120; the light produced by the interaction of the object sample with the excitation light is detected in situ by the detector assembly 120 or other suitable spectrometer to obtain molecular spectral data and atomic spectral data of the object sample.
Illustratively, in step S3, the molecular spectral data and the atomic spectral data may be received by the processor 140 from the detector assembly 120 or spectrometer and processed, such as compared to standard spectra in a database, to determine the composition of the object sample and the content of the elements it contains. As described above, the molecular spectral data may include at least one of inelastic scattering spectral data and absorption spectral data of the object sample, and the atomic spectral data may include X-ray fluorescence spectral data of the object sample.
In some examples, in step S1, first excitation light for illuminating the object sample is emitted by the first excitation light source 111, and second excitation light for illuminating the object sample is emitted by the second excitation light source 112.
In some examples, in step S2, the first excitation light is directed to the object sample by the first sub-optical path assembly 131, and the light generated by the interaction of the object sample and the first excitation light is directed to the first detector 121, and the light generated by the interaction of the object sample and the first excitation light is detected by the first detector 121 to obtain first molecular spectral data of the object sample; the second excitation light is guided to the object sample by the second sub-optical path assembly 132, and the light generated by the interaction between the object sample and the second excitation light is guided to the second detector 122, and the light generated by the interaction between the object sample and the second excitation light is detected by the second detector 122 to obtain the atomic spectrum data of the object sample.
In some other examples, step S1 may further include: emitting third excitation light for irradiating the object sample by the third excitation light source 113; the third excitation light is directed to the object sample by the third sub-optical path assembly 133, and the light generated by the interaction of the object sample and the third excitation light is directed to the third detector 123; light generated by the interaction of the object sample with the third excitation light is detected by the third detector 123 to obtain second molecular spectral data of the object sample.
The light detected by the detector may include inelastically scattered light, reflected light, diffusely reflected light, attenuated totally reflected light, or transmitted light from the object sample.
Similarly, as described above, the first excitation light or the third excitation light may include one of monochromatic laser light and infrared light, and the second excitation light may include X-rays; the first or second molecular spectral data may include one of inelastic scattering spectral data and absorption spectral data of the object sample, and the atomic spectral data includes X-ray fluorescence spectral data of the object sample.
In some embodiments, the method may further include step S4: and determining whether the content of harmful elements or substances in the object sample exceeds the standard. Illustratively, the harmful elements or substances include at least one of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers, which may be used to determine whether a solid article such as plastic is solid waste. In step S6, when it is determined that the content of the harmful elements or substances in the object sample exceeds the standard or the limit, the object sample may be determined to be suspected of belonging to waste (e.g., consubstantial waste), and may be sent to a more specialized laboratory for accurate detection determination.
In some embodiments, the method may further include step S5: determining the compositional uniformity of the object sample. For example, light generated by the interaction of the object sample with the excitation light at the different locations may be detected by the detector assembly to obtain molecular spectral data having multi-dimensional spectral information including spectral data associated with the composition of the object sample at each of the different locations, and then the composition of the object sample at the different locations may be obtained by the processor based on the multi-dimensional spectral information to determine whether the composition of the object sample at the different locations is consistent. When it is determined that the components of the object sample at different positions are not consistent, it may be determined in step S6 that the object sample has a suspicion of belonging to waste (e.g., solid waste).
As mentioned above, determining the composition of the object sample at different locations may be performed by: changing the irradiation position of the excitation light on the object sample by exciting the relative motion between the light source assembly and the object sample; alternatively, the irradiation position of the excitation light on the object sample is changed by changing the optical path of the excitation light to the object sample by the relative movement between the optical path member and the movement of the object sample, or by the optical path member fixedly positioned with respect to the object sample, as shown in step S7.
Further, before, after or during the above steps, the method may further comprise the steps of:
s8: monitoring the abnormal odor emitted by the object sample on site to obtain odor data of the object sample; and/or
S9: the radiation dose of the radiation of the object sample is monitored in situ to obtain radiation dose data of the object sample.
After obtaining the odor data of the sample, it may be determined by the processor whether the odor emitted by the sample is abnormal based on the odor data (step S10). After obtaining the radiation dose data of the sample, it may be determined by the processor whether the radiation dose of the sample is out of compliance based on the radiation dose data (step S11). Therefore, when the radiation dose of the object sample exceeds the standard and the object sample is solid, the object sample can be judged to be suspected to belong to solid waste; when the odor emitted by the object sample is abnormal and the object sample is solid, the object sample can be judged to be suspected to belong to solid waste.
