The CAP88 (Clean Air Act Assessment Package - 1988) computer model is a set of computer programs, databases and associated utility programs for estimating dose and risk from radionuclide emissions to air. It is used as a regulatory compliance tool by EPA under the National Emissions Standard for Hazardous Air Pollutants (NESHAP).
In Version 4, users will find three significant changes:
- age-dependent radionuclide dose and risk factors for ingestion and inhalation
- additional radionuclides
- changes in the file management system
EPA is offering two training classes to familiarize users with the recently released Version 4.
