Abstract
Radiation absorbed doses to various organs and tissues of members of the public due to ingestion of 3H, 131I and 137Cs are given in ICRP Publication 67. As these dose coefficients are truly applicable to ICRP Reference Man, the methodology of Yamaguchi was utilised to compute dose transformation factors (DTF) for estimating the dose coefficients in Indian adults for these radionuclides. After multiplying these dose coefficients with the appropriate tissue weighting factors recommended in ICRP Publication 60, the effective doses were calculated. The effective doses thus derived are multiplied by a suitable factor to take into account the different biological half-lives of these radionuclides in Indian subjects. On anatomical considerations alone, an average Indian receives 3-15% higher doses than his ICRP counterpart, however, when physiological differences between the two groups are also considered for the same amount of ingested activity of these radionuclides, the effective doses come out to be much less in an average Indian.
