Radioactive Materials

The Nuclear Regulatory Commission completed an agreement with the State of Minnesota to assume part of the agency’s regulatory authority over certain radioactive materials in the state. On March 31, 2006, Minnesota became the 34th state to sign such an agreement with the Nuclear Regulatory Commission.

Under the agreement, the Nuclear Regulatory Commission has transferred to Minnesota the responsibility for licensing, rulemaking, inspection and enforcement activities for: (1) radioactive materials produced as a result of processes related to the production or utilization of special nuclear material; (2) uranium and thorium source materials; and (3) special nuclear material in quantities not sufficient to form a critical mass.

The Nuclear Regulatory Commission transferred approximately 170 licenses, most for medical and industrial uses of radioactive material, to Minnesota’s jurisdiction. The Nuclear Regulatory Commission retained jurisdiction over a number of activities identified in 10 CFR Part 150, including regulation of commercial nuclear power plants and federal agencies using certain nuclear material in the state. In addition, the Nuclear Regulatory Commission retained authority for the review, evaluation and approval of sealed sources and devices containing certain nuclear materials manufactured in Minnesota and distributed throughout the country.

Proposed Amendment to the Rules Governing Radioactive Materials, Minnesota Rules, Chapter 4731

The Minnesota Department of Health is proposing to amend the radioactive materials rules (Chapter 4731) to incorporated changes from 8 Nuclear Regulatory Commission regulation updates. This is necessary to maintain compatibility with the federal requirements, required by our agreement. In addition to incorporating Nuclear Regulatory Commission changes, there are also some Minnesota Department of Health initiated changes.
