multi-agency workgroup

The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) Workgroup is an ongoing, collaborative effort to bring consistency to the methods and processes used to demonstrate compliance with federal and state radiation regulations. Workgroup members represent four federal agencies that have the primary responsibility for managing radioactive materials: the Environmental Protection Agency (EPA), the Nuclear Regulatory Commission (NRC) the Department of Energy (DOE) and the Department of War (DOW).
