REDIQ: a computer program for estimating health effects from inhalation and ingestion of radionuclides
The computer program REDIQ calculates the risk equivalence of dosage from internally deposited radionuclides to dosage from external whole-body irradiation. The calculation gives an estimate of the microcurie intake per nuclide that would result in a risk equivalent to receiving 1 rem of external whole-body irradiation. The program allows for internal deposition resulting from either inhalation of radioactive aerosols or ingestion of contaminated food. The inhalation portion of REDIQ was taken from the computer program DACRIN, which uses the models of the respiratory tract adopted by the Task Group on Lung Dynamics. REDIQ also uses a simple exponential model for retention by an organ of interest, and the gastrointestinal tract model of the International Commission on Radiological Protection (ICRP). For each nuclide specified, the program first calculates the radiation dose per microcurie intake by inhalation or ingestion to any of 23 organs and tissues. A maximum of 10 organs may be specified for any one case. The values for dose per microcurie intake are then coupled with relative risk values for each organ being considered, to arrive at the estimated intake equivalent to 1 rem of external whole-body irradiation.
