Radioactive Materials Program

Wisconsin Stats. § 254.365 requires that any person who possesses, uses, manufactures, transports, stores, or transfers radioactive materials in Wisconsin must have a radioactive materials license. Effective August 11, 2003, the Department of Health Services (DHS) licenses and inspects byproduct, source, special nuclear, naturally occurring, and accelerator-produced radioactive materials in Wisconsin (unless exempted).
