航空伽马能谱测量工作人员在仪器标定及实验过程中受照剂量的评估

THE EVALUATION OF RADIATION DOSE RECEIVED BY THE WORKER OF AIRBORNE GAMMA-RAY SPECTROMETRY DURING INSTRUMENT CALIBRATION AND EXPERIMENTS

航空伽马能谱测量应用越来越广泛。为了保证航空伽马能谱测量的质量,需要定期利用标准放射源或实验放射源对仪器进行标定和检测,但是缺乏对相关工作人员受照水平的评估。笔者通过测量工作人员在开展航空伽马能谱测量仪器标定及放射源实验过程中的外照射剂量率,估算个人外照射剂量,并与航空、放射性医疗等其他活动的受照剂量进行对比,评价航空伽马能谱测量工作人员的受照水平。

Airborne gamma-ray spectrometry has been widely used. To ensure the measuring quality of airborne gamma-ray spectrometry, we need to calibrate instruments regularly. However, very insufficient attention has been paid to the evaluation of the radiation dose received by workers. This paper evaluates personal radiation dose of the worker of airborne gamma-ray spectrometry according to the dose rate data recorded during the instrument calibration and experiments, and compares it with doses of other activities so as to reflect the radiation level.
