公众成员某些放射性核素的食入剂量系数

INGESTION DOSE COEFFICIENTS FOR MEMBERS OF THE PUBLIC FROM INTADE OF RADIONUCLIDES

本文根据ＩＣＲＰ６７号出版物，列出了４６个放射性核素对于３个月婴儿，１、５、１０、１５岁儿童和成人的食入剂量系数，这些核素都是由于人类的活动可能释放到环境中去的具有辐射防护意义的核素。文中还就核素在胃肠道中的吸收分数ｆ＿１、组织权重因子Ｗ＿Ｔ，及生物动力学数据等因素对剂量系数的影响进行了初步讨论。

Ingestion dose coefficients for members of the public from intake of some ra-dionuclides are given based on the ICRP publication 67. Influences off_1,W_T and biokineticdata on these coeffcients have also been discussed.
