The Massachusetts Department of Public Health's (MDPH) Bureau of Environmental Health’s (BEH) Radiation Control Program (RCP) protects the health and safety of the residents of the Commonwealth from the harmful effects of ionizing and non-ionizing radiation. RCP staff address a range of issues associated with radioactive materials including the regulation of specific radioactive sources, x-ray technology, nuclear medicine, professional training and licensure for radiologic technologists, laser registration, and more. The Nuclear Incident Advisory Team (NIAT) routinely participates in exercises to evaluate emergency plans to address nuclear power plant events.  RCP staff also work with other Bureau of Environmental Health Programs to carry out environmental monitoring activities and with local boards of health to regulate conditions related to the use of UV light in tanning facilities. This web site will guide you to information on regulatory matters, licensure, training, emergency planning and response, mammography, environmental monitoring, and many other issues related to the use of radiation in industrial, medical and environmental applications.

  • To reduce the likelihood that any person will receive a radiation dose that exceeds any limit specified in the Massachusetts Regulations for the Control of Radiation;
  • To prevent avoidable impacts to people and the environment from inadvertent or deliberate acts that involve any source or sources of radiation; and,
  • To assist in the assessment and mitigation of unacceptable health risks caused by radon in buildings located in the Commonwealth.


  • Administer the Massachusetts Regulations for the Control of Radiation, and related regulations, through comprehensive programs for developing and enforcing regulations that are compatible or consistent with federal regulations for protecting people and the environment from radiation;
  • Raise awareness on the Radiation Control Program's specialized assets as a strategic resource on radiation related matters;
  • Provide for excellence in regulatory and emergency response activities by maintaining principles of transparency, inclusiveness, efficiency, and integrity;
  • Maintain sufficient Nuclear Incident Advisory Team personnel and resources for working effectively within the National Incident Management System/Incident Command System in coordinating local, state and federal technical activities needed in a nuclear/radiological emergency;
  • Perform environmental monitoring and assessments required by law for nuclear power plants located in Massachusetts, or sited within10 miles from its borders;
  • Use current US Environmental Protection Agency guidelines to assist homeowners and municipalities in mitigating and avoiding health risks from radon, and engage the public on raising awareness about the health risks of radon.
