The U.S. EPA Superfund remedial program is finishing up a significant number of revisions to its guidance for the risk assessment process at radioactively contaminated Superfund sites. The six Preliminary Remediation Goal (PRG) and Dose Compliance Concentration (DCC) internet based calculators for risk and dose assessment at Superfund sites are being revised to reflect better science, revisions to existing exposure scenarios and new scenarios, and changes to match up more closely with the EPA chemical regional screening level calculator. A comprehensive set of revisions to the PRG calculator will be finished in November 2014. A revised version of the 1999 guidance document that provides an overview for the Superfund risk assessment process at radioactively contaminated sites, 'Radiation Risk Assessment At CERCLA Sites: Q and A' was issued on June 13, 2014 reflects Superfund recommended guidance and other technical documents issued over the past 15 years. Also on June 13, 2014 EPA issued a new tool-kit comprised of 22 fact sheets that was developed to help the general public understand more about EPA's risk assessment process used at radioactively contaminated Superfund sites.
