Technical solution provided in an embodiment of the present invention is introduced with reference to the accompanying drawings of the specification.
Referring to Figure 1, the embodiment of the invention provides a kind of radiation detector, which includes shielding case, sets
At least one first detector and at least two second detectors and processor being placed in shielding case.Wherein, outside shielding case
Or it is internal equipped with metal shield materials；At least one first detector is for detecting β ray radiation, at least two second detectors
For detecting other ray radiations in addition to β ray, at least one first detector is located at first layer, and at least two second visit
It surveys device and is located at the second layer；Processor and at least one first detector and at least two second detectors communicate to connect, for connecing
The first data from each first detector are received, and receive the second data from each second detector, and are based on first
Data and the second data determine the corresponding nuclear element of β ray and the corresponding nuclear element of gamma-rays of detection.
Specifically, as shown in Figure 1, Fig. 1 includes Radiation emitting sources 10 and radiation detector, in this exemplary embodiment,
Radiation emitting sources 10 include at least Beta-ray nuclear element and gamma-ray nuclear element.The radiation emitting nuclear element of Radiation emitting sources,
As shown in Fig. 1 arrow direction, radiation detector can identify one or more radioactive nucleus elements in Radiation emitting sources 10.
Radiation detector includes shielding case 20 and the first detector 30 and the second detector 40 that are placed in shielding case 20.
In possible embodiment, the first detector 30 and the second detector 40 are PN junction diode detector, alternatively, being also possible to it
He can detect β ray and gamma-ray detector.Shielding case 20 is by metal shield materials such as copper strips, copper wire, silver-plated copper
Band etc. is made, and prevents the first detector 30 and the second detector 40 by electromagnetic interference as far as possible.In possible embodiment, shielding
Cover 20 can also be made of other materials, if be made of other materials, the outside of shielding case 20 or internal cladding gold
Belong to shielding material.
In embodiments of the present invention, at least one first detector 30 is located at first layer, is mainly used for detecting β ray, until
Few two the second detectors 40 are located at the second layer, are mainly used for detecting gamma-rays, wherein first layer and second layer difference.Specifically
Ground shows first detector 30 and two the second detectors 40 continuing with referring to Fig. 1, Fig. 1, it can be seen that two second
Detector 40 is located on the same floor, i.e., for same reference planes (dotted line signal), two the second detectors 40 are apart from this
The height distance of reference planes is close or consistent.And the first detector 30 apart from the reference planes compared to the second detector 40
It says farther out.Although Fig. 1 illustrates only first detector 30 and two the second detectors 40, radiation detector be can wrap
It includes any amount of first detector 30 and the second detector 40 enables radiation detector to transport in the manner described above
Turn.
In some alternative embodiments, between two the second detectors 40 adjacent at least two second detectors 40
Distance be greater than or equal to first distance, to prevent the electric signal crosstalk between two adjacent the second detectors 40 as far as possible, that
This influences the signal of received radiation source radiation.It, may between two adjacent the second detectors 40 if first distance is shorter
Can also there be crosstalk, only the influence of crosstalk is smaller.And if first distance is longer, the length of shielding case 20 is also longer,
The volume of entire radiation detector is not readily portable with regard to larger.For this purpose, first distance can be in the embodiment of the present invention
1.0cm, more preferably can be 1.5cm, both can guarantee and has protected between two adjacent the second detectors 40 without electromagnetic crosstalk, and as far as possible
The volume for demonstrate,proving radiation detector is small as far as possible, easy to carry.First detector 30 is fixed at least two second detectors 40
On any one second detector 40, such as the first detector 30 can be closely adhered on the surface of second detector 40,
Such first detector 30 is that it is whole to reduce radiation detector as long as the second detector 40 is fixed for support with the second detector 40
It is a by external force collision when the first detector 30 a possibility that shaking.
In the embodiment of the present invention, the size of shielding case 20 is according to the quantity of the first detector 30 and the second detector 40 and big
Small determination.The shape of shielding case 20 can be rectangle or other shapes, with no restriction to this embodiment of the present invention.Shielding case
20 volume is small as far as possible so that radiation detector is operable as portable, handheld device.
In addition, in the embodiment of the present invention, the setting of at least one the first detector 30 and at least two second detectors 40
Position is comparatively concentrated, and the area of detector is reduced, it is separately positioned compared to each detector for, detection can be improved
Accuracy, to improve detection efficient.
Continuing with referring to fig. 2, in the embodiment of the present invention, shielding case 20 is equipped at the position opposite with the first detector 30
Penetrating region 60, penetrating region 60 can be provided with the front of the first detector 30, and size guarantees that the first detector 30 is completely naked
Dew, so that β ray can be radiated to the search coverage of the first detector 30 by penetrating region 60.In some optional embodiments
In, penetrating region 60 can be the opening that shielding case 20 opens up and be formed by, since Beta-ray penetration capacity is weaker, if
The thickness of shielding case 20 is thicker, then β ray can not penetrate, natural first detector 30 can not detect β ray.Due to first
Detector 30 and the second detector 40 since blocking for shielding case 20 is actually sightless, in Fig. 2, with dotted line
Illustrate the first detector 30 and the second detector 40.
The shading piece that β ray can penetrate is equipped in the embodiment of the present invention, at penetrating region 60, to guarantee the first detection as far as possible
Light environment around device 30, which meets, detects Beta-ray requirement.In some alternative embodiments, shading piece can be by metal
The thickness of metal layer made of material, the metal layer can be located within the scope of the first preset thickness, guarantee the first detector 30 weeks
The illumination brightness enclosed is lower than the first brightness value, meets and detects Beta-ray requirement.If the thickness of metal layer is thicker, may lead
Cause β ray that can not penetrate, and if the thinner thickness of metal layer, the ability of metal layer to shut out the light is weaker, shaded effect
It is poor.In the embodiment of the present invention, metal layer can be aluminium foil or other possible metal materials, the first preset thickness range
For in (0.22mm, 0.26mm), the thickness of metal layer can be any one value within the scope of the first preset thickness, it is preferable that
Metal layer with a thickness of 0.25mm, not only there is good shaded effect, but also β ray can be made to penetrate.
In embodiments of the present invention, it can be communicatively coupled continuing with referring to Fig. 1, the first detector 30 and the second detector 40
To processor 50, processor 50 can be located at the outside of shielding case 20, and receive the signal and second of the first detector 30 detection
