目的验证不同批次的玻璃管热释光元件用于测量时结果是否具有可比性。方法在不同实验条件下对不同批元件测量后进行比对。结果在累积受照剂量不低于0.5mGy,不同批次管具可比性,但在环境水平测量中则实验组结果相差较大。结论在不低于0.5mGy受照剂量时,监测其结果具可比性,其下限值可通过室验进一步获得;而对本底水平的监测,结果相差较大,无可比性。
Objective To verify the comparability of different batches of glass tube thermoluminescent devices used in the measurement. Methods Under different experimental conditions, different batches were measured and compared. The results of the cumulative exposure dose of not less than 0.5mGy, comparable to different batches of pipes, but in the measurement of environmental levels the experimental group results vary greatly. Conclusion When the dose is not lower than 0.5 mGy, the results of the monitoring are comparable, and the lower limit can be obtained by laboratory test. However, the monitoring of the background level is quite different and the results are not comparable.
