3. DESCRIPTION OF PROBLEM OR FUNCTION

SFACTOR estimates the average dose equivalent S (rem/uCi-day) to each of a specified list of target organs per microcurie-day residence of a radionuclide in source organs in man. Source and target organs of interest are specified in the input data stream, along with the nuclear decay information. The SFACTOR code computes components of the dose equivalent rate from each type of decay present for a particular radionuclide, including alpha, electron, and gamma radiation. For those transuranic isotopes which also decay by spontaneous fission,  components of S from the resulting fission fragments, neutrons, betas, and gammas are included in the tabulation. Tabulations for all components of S are provided for an array of 22 source organs and 24 target organs for 52 radionuclides in an adult.
