A multi-detector radiation protection detection method and detection system

Abstract

The invention discloses a multi-detector radiation protection detection method for protection detection of radiation working places. With the adoption of the method disclosed by the invention, the number of times of exposing (starting up) a ray device in a detection process can be reduced, damages to bulb tube are reduced, the accuracy of a detection result is improved, the working efficiency of detection is improved, and harms to bodies of detection workers are reduced. The invention further discloses a multi-detector radiation protection detection system.

Description

technical field [0001] The invention relates to the technical field of radiation protection detection, in particular to a multi-detector radiation protection detection method and detection system, which are suitable for protection detection in various radiation workplaces. Background technique [0002] According to the "Administrative Measures for the Safety and Protection of Radioisotope and Radiation Devices" (Decree No. 18 of the Ministry of Environmental Protection), all units that produce, sell, and use radioisotope and radiation devices should conduct radiation monitoring on relevant sites in accordance with the national environmental monitoring regulations. At the same time, the "Regulations on the Administration of Radiation Diagnosis and Treatment" (Decree No. 46 of the Ministry of Health) also stipulates that medical institutions should regularly conduct radiation protection tests on radiation diagnosis and treatment workplaces, radioisotope storage places and prote...

Problems solved by technology

Since the exposure (start-up) time of the radiation device is very short, each time a point is measured, it needs to be exposed (started up) once to complete the complete protection detection of multiple detection points in a radiation workplace. Finally, the radiation device needs to be continuously More than 10 times of exposure, resulting in a large number of continuous exposures of the radiation device in a short period of time, damaging the tube; and because the exposure (start-up) time of the radiation device is very short, the exposure (start-up) time of the radiation device is often out of sync with the detection time , the detection results are often biased and inaccurate; and for a radiation device workplace, there are multiple points to be detected, and the detection personnel need to hold the detection instrument to detect all the above-mentioned multiple points to be detected, which is time-consuming and laborious. If one test of a point to be tested is unsuccessful, the tester has to repeat the test many times until it succeeds, and the test work efficiency is low; and every time a point is measured, the tester must reach the test point with a handheld device, although under normal circumstances , the radiation dose is low, and will not cause obvious negative effects on the health of the inspectors. However, the radiation with a low dose is still radiation after all. Long-term inspections of multiple points and exposure to radiation for a long time are obviously harmful to the health of the inspectors. Health is only bad, not good. Further, in case of unqualified protection, inspectors conduct inspections without knowing it, and they will be exposed to excessive radiation, which will endanger health.
