Radioactive materials may be used only at the following UWM facilities as authorized by the NRC: Main (Kenwood) Campus; the Great Lakes WATER Institute, 600 E. Greenfield Avenue (See Section 20); the UWM Field Station, Saukville, WI (See Section 21); and aboard Authorized UWM Research Vessels (See Section 22).

A radionuclide laboratory is an enclosed space separated from adjacent areas by a floor, ceiling, and fixed walls with closable and lockable doors and windows. If unsealed sources of radioactive materials are used anywhere within the enclosure, the entire room is considered a radioactive materials area.

The Authorized User must provide and use adequate shielding so that exposure to individuals working with or near radioactive materials are kept as low as reasonably achievable (ALARA; See Section 11).

Fume hoods must have adequate air flow to ensure that airborne radionuclide levels in restricted or controlled areas and exhaust effluents are maintained below the allowed effluent concentrations established by the NRC. Wisconsin Department of Commerce codes require an average face velocity of 100 FPM (feet per minute). Typically, radionuclide fume hoods must have a discharge rate of <1000 CFM (cubic feet per minute). Consult with University Safety and Assurances at 229-6339 to have your hood tested. Contact the Radiation Safety Program before using volatile radioactive materials in hoods. Special hood requirements when using radioiodine and other volatile radionuclides are discussed in Section 14.

Radioactive materials, including wastes, must be secured against unauthorized removal. Authorized Users are responsible for the security of all radioactive materials in their possession including radioactive wastes in storage. See Section 9 for more information on security.
