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.
