Welcome to the EPA's "Dose Compliance Concentrations for Radionuclides at Superfund Sites" (DCC) user's guide. Here, you will find descriptions, equations, and default exposure parameters used to calculate the dose-based DCCs. If this is your first time using the DCC Calculator, it is strongly recommended that you first read "Radiation Risk Assessment At CERCLA Sites: Q & A". Additional guidance is also provided on sources of parameters and proper DCC use. It is suggested that users read the DCC FAQ page before proceeding. The user guide is extensive, so please use the "Open All Sections" and "Close All Sections" links below as needed. Individual sections can be opened and closed by clicking on the section titles.
