3. DESCRIPTION OF PROGRAM OR FUNCTION

RADRISK estimates radiation dose rates to various human organs from inhalation or ingestion of radioactive materials, and the health effects in a reference population as a result of this exposure.
top ]
4. METHOD OF SOLUTION

The amount or radioactive material present in various organs as a function of time is computed by solving a set of differential equations. This activity is multiplied by dosimetric S  factors to compute the dose rate. The dose rates over the lifetime of the cohort are then processed through a life-table actuarial analysis to estimate incremental cancer deaths in the cohort, taking into consideration all competing risks.

6. TYPICAL RUNNING TIME

Running time will depend on the nature of the exposure case of concern. Illustrative examples are given below for  a wide range of radionuclides; each case consists of chronic inhalation of the given radionuclide over the lifetime of the cohort. Some example cases include: Pu-239, which with 1 significant nuclide in the decay chain took 1.5 seconds of CPU time, Pb-210 with 3 significant nuclides in the decay chain took 3 CPU seconds, and Ra-226 with 9 signficant nuclides in the decay chain took 20 CPU seconds. RADRISK requires 16 CPU seconds to compile, 1 CPU second to link and the sample problem executes in 5 CPU seconds.
