摘要

The U.S. Environmental Protection Agency (EPA) Superfund 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 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 & A" is being completed that will reflect Superfund recommended guidance and other technical documents issued over the past 12 years. This presentation would go over those changes that are expected to be finished by this summer.
