Title: INGDOS: a conversational computer code to implement US Nuclear Regulatory Commission Regulatory Guide 1. 109 models for estimation of annual doses from ingestion of atmospherically released radionuclides in foods
Abstract: INGDOS is a conversational FORTRAN IV program which utilizes models described in U.S. Nuclear Regulatory Commission Regulatory Guide 1.109 for calculating: (1) concentrations of airborne radionuclides in foods; and (2) annual doses to various organs of man from ingestion of foods contaminated by radionuclides released to the atmosphere. An exception to the implementation of models described in the Regulatory Guide is the adoption of other previously described models for estimation of doses for /sup 3/H and /sup 14/C. An on-line data base provides default values for most of the parameters required in the calculation of these quantities. In most cases the program allows the user to change any of these values for a particular run. With the exception of /sup 3/H and /sup 14/C, the calculation of nuclide concentrations in and on vegetation at a given location is based on the rate of deposition of the nuclide at the given location, which is the product of the ground-level air concentration and the deposition velocity of the nuclide. The last two quantities must be supplied by the user of the code for each nuclide other than /sup 3/H or /sup 14/C involved in the run. As output from INGDOS, the user may have any (or all) of 11 tables printed which specify nuclide concentrations and annual organ doses via various pathways as well as certain ratios involving these quantities. The models for calculating nuclide concentrations and organ doses are discussed, and information is provided concerning the use of the code and its data base.
