Radiation Protection

Activities designed to minimize radiation exposure to the general public are described below.  Also provided are links to the Wisconsin statutes and rules that govern these activities.

Information and Resources


Environmental Monitoring  

The State of Wisconsin monitors the environment for radiation emission in the areas around the five nuclear power facilities that affect Wisconsin.  

Incident Response and Advisory Assistance

DHS has a key role in protecting the citizens of Wisconsin and their property in events involving radioactive materials other than a nuclear power plant origin. This site provides information for professionals involved in planning for and responding to a radiological emergency. Contact: 608-267-4797. Sample Radioactive Emergency Posting Sign (PDF, 14 KB)

Radioactive Materials

The U.S. Nuclear Regulatory Commission and the Governor signed an agreement transferring regulatory authority over byproduct, source and special nuclear materials to the State of Wisconsin. Wisconsin became the 33rd agreement state effective August 11, 2003. (See Who regulates on the NRC website for a description of agreement states.)

As an agreement state, the Department is responsible for licensing and inspecting the above-named materials, except at nuclear plants and federal facilities. Radioactive materials are commonly used for medical diagnosis and treatment, industrial processes, research and education. Contact: Mark Paulson, 608-264-6516 Radioactive Materials Supervisor.

Radiological Emergency Preparedness

A Radiological Incident Response Plan has been developed to handle all radioactive emergencies at nuclear power plants in or near Wisconsin. Activities include: developing and conducting training for state, local and utility emergency responders; procedure development; exercise scenario development; and participation in scheduled nuclear plant emergency preparedness exercises evaluated by the Federal Emergency Management Agency (FEMA). Contact: Jason Hunt at 608-266-9443, Dan Stefenel at 608-266-0468, or Charles Adams at 608-267-4794.


The State of Wisconsin supports a variety of radon activities, including research, education and a statewide network of Radon Information Centers (RIC).  The RICs provide information and advisory assistance to the public regarding radioactive radon gas.  Contact: 608-267-7199.

X-ray and Tanning equipment/ Mammography facilities Inspection

The State of Wisconsin works to minimize the public's unnecessary exposure to radiation by inspecting and registering all x-ray and tanning devices for compliance with state radiation protection regulations. Mammography facilities are inspected for compliance with federal regulations.  Contact : William Balke, Supervisor, at 608-267-4787.
