摘要
目的:应用TASLIMAGE测量系统测量中子剂量刻度系数,研究测量系统在中子个人剂量监测中的应用。方法:依据国家标准GBZ207-2008"外照射个人剂量系统性能检验规范"等的推荐方法,应用TASLIMAGE测量系统测量经中子源刻度过的CR39中子个人剂量计,得到中子剂量刻度系数;对TASLIMAGE系统测量的中子剂量进行检测并应用该系统进行中子个人剂量监测。结果:实验获得了符合性较好的剂量线性曲线,刻度系数为513.57tr/cm^2·mSv^(-1),中子剂量与参考剂量的测量偏差最大为7.34%。结论:应用TASLIMAGE系统进行中子个人剂量监测,使用方便、高效,符合国家标准GBZ128-2013职业性外照射个人监测规范等相关标准的要求,可为今后开展中子个人剂量监测提供理论依据,奠定实验基础。
Objective： To measure the neutron dose calibration coefficient of CR39 and the application of the TASLIMAGE system in neutron individual dose monitoring. Methods： According to the requirements of GBZ207-2008, neutron dose calibration coefficients were obtained by TASLIMAGE measurement system; Tests were performed to evaluate the precision of neutron dose of TASLIMAGE system. Meanwhile, the system was applied to the neutron dose monitoring. Results： The calibration coefficient of CR39 was 513.57tr/cm2,mSv-1, and the relative measuring deviation of neutron dose was 7.34%. Conclusion： The TASLIMAGE system is reliable and efficient, and that it could be a useful tool for neutron dose monitoring.
