1989 the Environmental Protection Agency (EPA) issued final rules for radionuclide emissions to air under 40 CFR 61, National Emission Standards for Hazardous Air Pollutants (NESHAPS). Emission monitoring and compliance procedures for Department of Energy (DOE) facilities (40 CFR 61.93(a) ) require the use of CAP-88 or AIRDOS-PC computer models, or other approved procedures, to calculate effective dose equivalents to members of the public. The CAP88 (which stands for Clean Air Act Assessment Package - 1988) computer model is a set of computer programs, databases and associated utility programs for estimation of dose and risk from radionuclide emissions to air. EPA modified the ORNL mainframe program AIRDOS in 1979 to create AIRDOS-EPA (Mo79). The AIRDOS-EPA code was further modified to incorporate various dose and risk coefficients. AIRDOS-EPA (1982) used RADRISK (1980) database files for dose and risk coefficients. RADRISK calculated isotope dose and risk and stored them in binary card image format. The DARTAB (1981) code was developed to convert RADRISK files to the format used by AIRDOS-EPA. AIRDOS (1984) used doses from DARTAB rather than the doses calculated directly by AIRDOS. To make compliance calculations easier for individuals without access to a mainframe computer, EPA developed the AIRDOS-PC program that was used from 1982 to 1986. AIRDOS-PC was succeeded by AIRDOS2 which was the predecessor of CAP88-PC. At the same time PC versions of RADRISK and DARTAB were developed. All were combined in CAP88-PC (1988). Purpose and Version History The original CAP88-PC software package, version 1.0, allowed users to perform full-featured dose and risk assessments in a DOS environment for the purpose of demonstrating compliance with 40 CFR 61.93(a). CAP88-PC provided the CAP-88 methodology for assessments of both collective populations and maximally-exposed individuals. The complete set of dose and risk factors used in CAP88 was provided. CAP88-PC differs from the dose assessment software AIRDOS-PC in that it estimates risk as well as dose, offers a wider selection of radionuclide and meteorological data, provides the capability for collective population assessments, and allows users greater freedom to alter values of environmental transport variables. CAP88-PC version 1.0 was approved for demonstrating compliance with 40 CFR 61.93(a) in February 1992. CAP88-PC version 2.0 provided a framework for developing inputs to perform full-featured dose and risk assessments in a Windows environment for the purpose of demonstrating compliance with 40 CFR 61.93(a). The changes from version 2.0 to version 2.1 included the addition of more decay chains, improvements in the Windows code error handling, and a modified nuclide data input form. CAP88-PC Version 3.0 marked a significant update to the version 2 system. Version 3 incorporated dose and risk factors from Federal Guidance Report 13 (FGR 13, EPA99) in place of the RADRISK data that was used in previous versions. The FGR 13 factors were CAP88-PC 4.1 Documentation Page 4 of 103 based on the methods in Publication 72 of the International Commission on Radiological Protection (ICRP72). In addition, the CAP88-PC database, user interface, and input/output files were modified to accommodate the FGR 13 data formats and nomenclature. CAP88-PC Version 4 was a significant modification to version 3 intended to improve usability, increase stability, update the datasets, and provide a more maintainable code base and documentation set for the future. Version 4 adopted age-dependent dose and risk factors and introduced a new code architecture that conformed to updated coding standards and data formats. Version 4 also moved the database of isotopic data to eXtensible Markup
