Abstract

A kind of nuclear radiation detector that can measure radioprotective dosage and distribution.The top layer of detector is the special material of a kind of radiation-screening, reduces the radiation damage of detector;The front end of detector has the protection cap that opening and closing is controlled, opens when needed, and protection detector is not by too much radiation destruction;After photoelectric sensor CCD collects radiation information, it is sent to process in chip, calculates the dosage of radioprotective, the Two dimensional Distribution of radiation is shown by liquid crystal display screen simultaneously, convenient operation and monitoring.If it exceeds the threshold value set, sensor alarm.Meanwhile, data can be stored by storage chip, facilitates consulting of later stage, and USB interface can transfer data to the composition of the further analyzing radiation of PC.

Description

A kind of nuclear radiation detector
Technical field
The present invention relates to a kind of instrument detecting radioprotective.Specifically provide a kind of method that can measure radioprotective quantity, permissible The dosage of detection radioprotective and distribution.
Background technology
At present, the detector that can simultaneously detect radioprotective dosage and Two dimensional Distribution image on the market is few not yet, substantially can divide Being two kinds, a kind of is traditional instrument measuring radiation, such as gas detector, scintillation detector and semiconductor detector etc., this A little detectors Technical comparing in terms of measuring dosage is ripe, but the efficiency being used to detect Two dimensional Distribution image is not high enough, degree of accuracy The most not high enough;Also have a kind of nuclear radiation detector to utilize photoelectric sensor to gather information, showing two-dimensional distribution image space mask There is certain advantage, but they need to increase switching device before detector, and radioprotective is converted to visible ray, then by passing Sensor detects, and this mode conversion efficiency is the most relatively low, it is also difficult to obtain dosage information.
Summary of the invention
Present invention aim to address the deficiency of nuclear radiation detector described in background technology, it is provided that a kind of high efficiency detection core spoke The dosage penetrated and the detector of distribution.
The present invention takes optoelectronic sensor CCD as sensor, directly gathers the information of radioprotective, in the effect processing chip The dosage information of numerical value can be converted to down, the Two dimensional Distribution of radioprotective can be obtained again.
Advantages of the present invention has:
(1) dosage and the distribution of radioprotective can be detected, and increase memorizer, can directly display, or be connected to PC, The information collected is carried out the operation that the analysis of spectrum etc. in later stage is required.
(2) outside detector, increase the special material of radiation-screening.
(3) operator can arrange threshold value according to different occasions, when radioprotective dosage exceedes threshold value, and can be with automatic alarm.
(4) front end of detector has the protection cap that opening and closing is controlled, opens when needed, and protection detector is not by too much radiation Destroy.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of nuclear radiation detector;
Fig. 2 is the side view of nuclear radiation detector;
Fig. 3 is the top view of nuclear radiation detector;
Fig. 4 is the upward view of nuclear radiation detector.
Detailed description of the invention
The present invention can be used in the places such as pharmaceutical factory, laboratory, stone pit, metal Treatment stations;May also be used for checking subsoil water Pollution, masonry work material and some areas nuclear radiation pollution etc., the process implemented in different occasions is similar to.Below with Detection positron22As a example by Na and detection karyomerite leakage, embodiment is described.
The top layer 1 of this radiation detector shell 2 is the special material with shielded nucleus radiation function, and the radiation reducing detector is damaged Wound.
(1) detection positron22Na
First load onto battery 19, cover the probe portion of detector with shade, arrest handle 3, press on and off switch 7, mirror The protection cap 18 of head is opened, and detector is started working.Photographic head 4 is directed at positron source22Na, electron irradiation ccd sensor 5, by processing circuit 6, image can be shown in LCDs 12.It can be seen that the background of black on the display 12 On have bright spot diverse location occur, it is simply that the image of positron.Press button 8 of taking pictures, it can be seen that have some bright spots mixed and disorderly Distribution, press display switching push button 10, the dosage of radiation can be checked on the display 12, press confirming button 15, figure Sheet and dosage information are stored in memorizer 16, check the most later.After detection, by and off switch 7 closure detector.Logical Cross usb 17 and be connected to computer, carry out the data analysis in later stage.
(2) detection karyomerite leakage
Radiation detector is taken the place being likely to occur leakage, loads onto battery 19, press on and off switch 7, the protection cap of camera lens 18 open, and detector is started working.Press and the button 14 of threshold value is set starts to set the dose threshold value of this occasion, by regulation Button 9 and 13 arranges threshold value, by display screen 12 i.e. observable, when arranging suitable, presses and determines key 15, represents and arranges Complete.
Cover the probe portion of detector with shade, arrest handle portion 3, camera lens 4 is directed at the position needing detection, core Ccd sensor 5 is irradiated in radiation, by processing circuit 6, can show image in LCDs 12.Press shooting push button 8, the two dimensional image of radiation can be seen on 12.Press display switching push button 10, radiation can be checked on the display 12 Dosage, now, press confirming button 15 and can be stored in memorizer 16.Data in memorizer can be done for transmission to computer in detail Thin analysis, such as by the kind of analyzing radiation, and the ratio etc. shared by various radiation.
If dosage exceedes the threshold value of setting, threshold value can be exceeded by display lamp 11 alarm.
When needing to measure one group of data, step is ibid.After measurement terminates, close power supply 7.
If the detailed comparisons in later stage to be carried out analyzes, then can send data to computer by usb 17, by analyzing software Analyze further.
