3. DESCRIPTION OF PROGRAM OR FUNCTION

DOSFACTER-DOE is a revision of  the DOSFACTER-II code. It estimates dose-rate conversion factors for exposure to photons and electrons emitted by radionuclides dispersed in the environment. The exposure modes considered are immersion in contaminated air, immersion in contaminated water, and irradiation at a height of 1 m above a contaminated ground surface. The source region for each exposure mode is assumed to be effectively infinite  or semi-infinite in extent with a uniform radionuclide concentration throughout the source region. The dose-rate factors are computed for a dose to 23 body organs and for an effective dose.
The present code differs from DOSEFACTER-II as follows: no body surface factors, " total body " factors replaced by " effective "
(weighted) factors, electron dose factors for the skin calculated for several depths, and output format. Non-SI units are used.

4. METHOD OF SOLUTION

For air and water immersion, the body-surface dose-rate factors were based on the conservation of energy requirement that all of the emitted energy is absorbed in the infinite medium. For ground-surface exposure, the body-surface dose-rate factors were calculated at a point 1 m above the ground using a point-kernel integration method and known specific absorbed  fractions for photons and electrons in air. For photons only, the dose-rate factors for 23 body organs were calculated for each exposure mode using the organ dose-rate factors for immersion estimated by Eckerman et al.
The radioactive decay data are taken from the data library DLC-80/DRALIST which is available from RSIC.
