Present report deals with a computer program which provides a method to calculates absorbed radiation dose of various organs from radionuclides internally distributed in the body. The program is based on the MIRD method and a transformation method which estimates absorbed doses for physiques different from the MIRD phantom, for example, those for Japanese people. Specific absorbed fractions for arm bones and leg bones were calculated in terms of the buildup method in order to estimate Japanese red bone marrow dose. Specific absorbed fraction for breast was estimated in the MIRD phantom by using the buildup method. The program list will be sent by request.
