目的探讨采用热释光法对闪光X射线发生装置进行放射防护监测的可行性。方法触发闪光X射线发生装置曝光7次,比较热释光法与几种常见直读式X射线检测仪的测量结果。结果发现热释光剂量计能够对闪光X射线装置发射的脉动X射线做出有效响应。并且在照射方向距X射线管10m以内,热释光法测量结果与理论推算值非常接近。结论通过对某研究所闪光X射线发生装置工作现场实际监测,证明热释光法可用于对闪光X射线装置进行放射防护监测。
Objective To explore the feasibility of using radiofrequency light to monitor the radiological protection of flash X-ray generator. Methods The exposure of the flash X-ray generator was triggered seven times. The results of thermoluminescence and several common direct reading X-ray detectors were compared. The results showed that the thermoluminescent dosimeter was able to respond effectively to the pulsating X-ray emitted by the flash X-ray device. And in the irradiation direction from the X-ray tube within 10m, the results of the thermoluminescence method and the theoretical estimates are very close. Conclusion The actual monitoring of the work site of a flash X-ray generator in a research institute proves that the TL method can be used for the radiological monitoring of the flash X-ray device.
