Hp(3)测量与量值传递研究进展

摘要/Abstract

摘要： 通过对国内外相关文献的调研,结合现行相关标准内容,介绍眼晶体剂量当量H_p(3)的测量以及量值传递过程中所使用的体模、转换系数等。圆柱体模已作为H_p(3)剂量计校准用体模,并被广泛推荐;剂量当量转换系数主要基于蒙特卡罗方法和经验公式计算得到;H_p(3)测量方法各异,主要基于热释光剂量测量系统。欧盟现已组织开展三次关于眼晶体剂量计的比对,在光子场中照射的比对结果比在β场照射的结果较好。但由于铅眼镜和铅面罩的应用,以及眼晶体敏感区域的划分,H_p(3)的测量与量值传递方法仍存在问题。

Abstract: Through a comprehensive literature investigation, combined with studying the contents of the current relevant standards, this paper investigates the phantom, conversion coefficients and lens dosemeter used in the measurement process. The cylindrical phantom has been used as a phantom for eye lens dose equivalent H_p(3) dosemeter calibration. The dose equivalent conversion coefficient is mainly calculated based on the Monte Carlo method and empirical formula. The H_p(3) measurement methods are various, mainly based on thermoluminescence dosimetry system. The EU has organized three relevant inter-comparisons. The comparison result of irradiation in photon field was better than the result of irradiation in β field. However, due to the application of lead glasses and lead masks, and the division of the sensitive area of the lens, there are still problems to be solved in the measurement and transmission of H_p(3).

Key words: eye lens dose, dose measurement, H_p(3)
