The EPA Has Released CAP88-PC Model, Version 4

The Environmental Protection Agency (EPA) has announced the availability of Version 4 of the CAP88–PC model on its website.

This version may be used to demonstrate compliance with the National Emission Standards for Hazardous Air Pollutants (NESHAP) applicable to radionuclides. Version 4 has many changes and improvements from previous versions. The most significant of these changes from a user perspective are the incorporation of age-dependent radionuclide dose and risk factors for ingestion and inhalation, the increase in the number of included radionuclides, and a change in the file-management system used by the program.

Operational Radiation Safety published a special issue on the use of CAP88 in 2013. Also, there will be a special session on NESHAPs at the 2015 HPS Annual Meeting in Indianapolis.
