Intruder dose pathway analysis code for onsite land disposal
The objective of the current project is to modify an existing pathway-to-man computer program, the MAXI1 computer program, for use by the US Nuclear Regulatory Commission (NRC) in reviewing proposed onsite burials of radioactive materials by its licensees. The policy of the NRC is to review proposed onsite burial of radioactive waste on a case-by-case basis. As part of our earlier work on this project, specific human intrusion scenarios were developed that consider various potential combinations of direct exposure to penetrating radiation, inhalation of airborne radionuclides, ingestion of agricultural products raised in contaminated soil, and ingestion of radionuclides in drinking water. As a continuation of our earlier efforts, enhancements to the ONSITE/MASI1 computer software package are being made that will account for additional optional shielding factors that could influence external exposure to penetrating radiation, provide options for alternative land-use conditions, and permit the user to select from a complete diet, meat diet, or vegetable diet. Additional modifications underway include (1) conversion to the ICRP 26/30 dosimetric system for assessing human exposure to radioactive materials and (2) inclusion of an optional 50-year effective committed dose equivalent calculation. The resulting computer software package will provide the necessary flexibility to conduct analyses of human-intrusion scenarios that are applicable to the terrestrial disposal of radioactive materials for a wide variety of conditions. 8 refs., 1 fig.
