摘要
本文总结了多年来玻璃管热释光剂量计在辐射环境监测中的实践经验,对累积剂量监测结果的影响因素进行了分析。结果表明,不同批次剂量计的宇宙射线响应及自辐照水平、分散性、不同检定单位的刻度系数、测量系统参考光源的稳定性和自然因素中气候季节降雨量的变化等因素,均可对测量结果可靠性造成影响。笔者提出了相关建议,以期为国内同行提供参考。
In this paper,years of practical experience of the glass tube thermoluminescence dosimeter(TLD)in radiation environment monitoring was summarized,and impact factors of reliability for environmental monitoring were analyzed.This includes the cosmic ray response of different batches of dosimeters and the self-irradiation level,the dispersion,the calibration coefficients of different calibration units,the stability of the reference light source of the measurement system,and the changes in climatic and seasonal rainfall in natural factors,et al.Some valuable suggestions were presented,whick could provide reference experience for domestic counterparts.
