摘　　要：为实现β射线组织吸收剂量的量值复现,通过实验和模拟计算得到了基于90 Sr/90 Y和85 Kr源的辐射场和外推电离室参数,以及外推电离室相关修正因子,实现了展平过滤条件下组织吸收剂量率的量值复现。为后续参加β射线剂量相关的国际比对,进行β射线个人剂量当量H p(0.07)的量值传递提供基础。In order to reproduce the magnitude of the absorbed dose ofβ-ray tissue,the radiation field based on 90 Sr/90 Y and 85 Kr sources and the extrapolated ionization chamber parameters,as well as the related correction factors of the extrapolated ionization chamber,were obtained through experiments and simulation calculations,and flattening was achieved.The magnitude of the tissue absorbed dose rate under the filter condition was reproduced.It provides a basis for the subsequent participation in the international comparison ofβ-particle raidation doses and the transfer ofβ-particle raidation personal dose equivalents H p(0.07).
