摘要
2011年ICRP在其出版的118号报告中大幅降低了职业照射眼晶体剂量限值,这一更改使得眼晶体剂量监测相关问题受到关注。近期发表的一系列文章在这方面进行了深入研究,并取得了重要进展。这些进展包括:明确了Hp(10)和Hp(0.07)剂量计在眼晶体剂量监测中的适用性,欧洲委员会(European Commission)支持的ORAMED项目开发了专门用于眼晶体个人剂量监测的TLD剂量计EYE-D及用于此剂量计刻度的圆柱形体模,Behrens等人建立了眼精细剂量计算模型等。本文结合这些重要背景,首先总结了ICRP降低眼晶体剂量限值的原因,其次较详细地对上述研究进展进行了概述,旨在为国内今后开展眼晶体剂量监测的研究和实践提供有价值的资料。
In 2011,ICRP remarkably decreased the occupational dose limit for eye lens in its 118 th publication. This change leads to unprecedented focus on the eye lens dose monitoring related problems.Recently,a series of related papers were published and some cosiderable progress were achieved. These progress may include： the suitability to use dosimeters in terms of Hp（ 10） and Hp（ 0. 07） for eye lens dose monitoring has been determined; ORAMED project supported by European Commission has developed the special eye lens dose monitoring TLD dosimeter which named EYE- D as well as the special cylinder phantom for calibration use, Behrens et. al have established a sophisticated eye calculating model. With these important background,this paper first concludes the reason why ICRP decreased the dose limit,then gives a comprehensive review to these new approached mentioned above.This paper aims to provide reference for the research and experiment on eye lens dose in China in the future.
