Description
Technical field
The utility model relates to Radiation monitoring and guard technology field, is specifically related to a kind of instrument that can be used for surface pollution monitor calibration that can be used for surface pollution monitor calibration.
Background technology
Department at nuclear power plant, reprocessing plant etc. containing hot operation, radioactivity supervision department and relevant radiomaterial applying unit etc. is all equipped with surface pollution monitor.This instrument can be measured α, the β particle pollution situation of body surface, to determine whether take the treatment measures such as decontamination, the personnel that prevent are by radioactive contamination.
Surface pollution monitor uses in a large number in radioactivity monitoring field, manufacturer is a lot, or because of application target difference or because use object difference, causing the detector size of surface pollution monitor to have different specifications, this brings many puzzlements to calibration of these instruments.A kind of instrument that can be used for surface pollution monitor calibration that the utility model proposes for this problem just.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of instrument that can be used for surface pollution monitor calibration, can simplify calibration process by this device, improves the calibration efficiency of surface pollution monitor.
For achieving the above object, the technical solution adopted in the utility model is as follows:
An instrument that can be used for surface pollution monitor calibration, comprises base, and the two ends of base have card article loose slot, are provided with two card articles that run through two ends card article loose slot in card article loose slot, and the below of card article has radioactive source groove.
Further, a kind of instrument that can be used for surface pollution monitor calibration as above, the distance of described card article and radioactive source groove is 5mm.
Further again, a kind of instrument that can be used for surface pollution monitor calibration as above, the distance of described card article and radioactive source groove is 10mm.
Further, a kind of instrument that can be used for surface pollution monitor calibration as above, the length of described base is 20cm, width is 15cm.
The beneficial effects of the utility model are: the instrument that can be used for surface pollution monitor calibration of the present utility model, by regulating card article, applicable to the detector of different size specification, make the more convenient convenience of the whole calibration process of surface pollution monitor, greatly improve and simplified calibration process.
Brief description of the drawings
Fig. 1 is the front view of a kind of instrument that can be used for surface pollution monitor calibration in embodiment;
Fig. 2 is the vertical view of a kind of instrument that can be used for surface pollution monitor calibration in embodiment.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is described in further detail.
Fig. 1 and Fig. 2 show respectively front view and the vertical view of a kind of instrument that can be used for surface pollution monitor calibration in the utility model embodiment, this instrument comprises base 1, the two ends of base 1 have card article loose slot 4, in card article loose slot 4, be provided with two card articles 3 that run through two ends card article loose slot 4, the below of card article 3 has radioactive source groove 2.
The instrument that can be used for surface pollution monitor calibration of the present utility model, be mainly used in the calibration of auxiliary surface contamination monitor, in the time of calibration, detector is placed on card article 3, radioactive source is placed in radioactive source groove 2, and card article 3 is through the card article loose slot 4 at two ends, and card article 3 exposes, so that at the interior free adjustment card article 3 of card article loose slot 4, to adapt to the detector of different size.
Surface pollution monitor uses in a large number relating to radioactive field, and its detector size has a lot of specifications, China's relevant criterion and code requirement, while examining and determine/calibrate these instruments, detector is fixed to the distance of radioactive source, is 5mm to α particle, is 10mm to β particle.In order to complete the calibration content of α particle and β particle of instrument, the card article 3 that can be used for the instrument of surface pollution monitor calibration in present embodiment is 5mm or 10mm with the distance of radioactive source groove 2, and detector is designed to 5mm or 10mm apart from the distance of radioactive source.
In present embodiment, the length of whole assisted calibration device is 20cm, and width is 15cm, and the length of base 1 is 20cm, and width is 15cm.
The instrument of surface pollution monitor calibration that can be used for of the present utility model is for α, the β calibration of surface pollution monitor, the surface contamination unit of α and β provides with Bq/cm2, but in fact, detector measurement be into the α that injects detector, β particle number, measuring unit is that cps(counts p.s.).Explorer count is directly proportional to surface contamination value, exists a scale-up factor that explorer count and surface contamination value are connected, and how accurately to find this scale-up factor to realize by calibration experiments, and this scale-up factor is called surface activity response.While using the instrument that can be used for surface pollution monitor calibration in present embodiment to carry out calibration experiments, by radioactive source, from the interior insertion of radioactive source groove 2, surface pollution monitor is placed on card article 3, and mobile card article 3, to adapt to the detector of different size, is carried out calibration experiments.Because the surface activity of radioactive source is known, by compared with the explorer count measuring, can obtain the surface activity response of instrument.In actual use, can obtain the surface contamination situation on object, wall, ground etc. by the surface activity response of explorer count and calibration, ensure the validity of measurement data.
In addition, in order to reduce the scattering of α, β and the bremstrahlen that β produces, the instrument entirety that can be used for surface pollution monitor calibration of present embodiment adopts pmma material, thereby calibration experiments is better carried out in the interference causing while reducing calibration.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if these amendments of the present utility model and within modification belongs to the scope of the utility model claim and equivalent technology thereof, the utility model is also intended to comprise these changes and modification interior.
