Internal Dosimetry Data and Methods of ICRP-Part 2, Volume 1: Committed Dose Equivalent and Secondary Limits

摘要

The International Commission on Radiological Protection (ICRP) Committee 2 on Secondary Limits has published its report updating secondary limits for the radiation protection of workers. Tabulations of the committed dose equivalent per unit intake of selected nuclides of interest to the nuclear industry are presented in this report. These values were used by the ICRP Committee 2 Task Group on Dose Calculations in etablishing the annual limits on intake for occupational exposure. Background data and information on the bone dosimetry methods of Committee 2 are presented, and the bases for the corresponding nominal absorbed fraction values recommended by the Committee for nonpenetrating radiations are examined. The energy dependence of these quantities is also examined, and a comparison is made between the Committee values and the results of additional Monte Carlo computations of the absorbed fraction.
