This paper reviews the ICRP Publications 110 and 116 describing the reference computational phantoms and dose conversion coefficients for external exposures. The International Commission on Radiological Protection (ICRP) in its 2007 Recommendations made several revisions to the methods of calculation of the protection quantities. In order to implement these recommendations, the DOCAL task group of the ICRP developed computational phantoms representing the reference adult male and female and then calculated a set of dose conversion coefficients for various types of idealised external exposures. This paper focuses on the dose conversion coefficients for neutrons and investigates their relationship with the conversion coefficients of the protection and operational quantities of ICRP Publication 74. Contributing factors to the differences between these sets of conversion coefficients are discussed in terms of the changes in phantoms employed and the radiation and tissue weighting factors.
本文回顾了国际放射防护委员会（ICRP）第110号和第116号出版物，这些出版物描述了用于外照射的参考计算体模和剂量转换系数。国际放射防护委员会（ICRP）在其2007年建议中对防护量的计算方法进行了若干修订。为了实施这些建议，ICRP的DOCAL任务组开发了代表参考成年男性和女性的计算体模，然后计算了各种理想化外照射类型的一组剂量转换系数。本文重点关注中子的剂量转换系数，并研究它们与ICRP第74号出版物中防护和操作量的转换系数之间的关系。根据所采用体模的变化以及辐射和组织权重因子，讨论了这几组转换系数之间差异的影响因素。
