摘要: 固定式环境γ辐射剂量率监测仪表是承担环境连续监测任务的主要设备,这类仪表通常不便于拆卸和安装,而且送检周期较长(一周左右),影响了连续监测点数据的连续性。为了固定式仪表的按期校准,结合蒙卡方法研制了便携式137Cs照射装置,利用PTW剂量计对辐射场进行标定,最后利用便携式照射装置对固定式环境γ辐射剂量率监测仪表进行现场校准实验。

Abstract: Fixed environmental gamma radiation dose rate monitoring instrument is the main equipment to undertake environmental continuous monitoring tasks, but its inconveniencies in terms of installation and removal, as well as it prolonged submission period (about a week) affects the continuity of its continuous monitoring data. For the on-time calibration of the instrument, a portable 137Cs irradiation device was developed using the Monte Carlo method with PTW dosimeter being adopted to measure dose rate of the radiation field. Finally, the portable irradiation device was used to calibrate on-site the fixed environmental gamma radiation dose rate monitoring instrument.

Key words: portable 137Cs irradiation facility, Monte Carlo, reference radiation field, on-site calibration
