External exposure to arbitrary distributions of radionuclides in soil

A program has been developed for MS-Dos personal computers which can generate dose coefficients for arbitrary distributions of radionuclides as a function of depth below the air-ground interface, using superposition of the dose coefficients for the monoenergetic planar sources. Coefficients can be computed for any of the 825 radionuclides having decay data in Publication 398 of the ICRP. Uniform and exponentially-distributed analystical source distributions are also available between any two depth boundaries. Coefficients are available both in SI and traditional units for individual organ, for effective dose equivalent as formulated in ICRP Publication 26, and for effective dose as formulated in ICRP Publication 60
