What is Radiation Safety?

Radiation safety aims at protecting users, staff, the general public and the environment from exposure to radiation through the proper management and disposal of all radioactive materials used in teaching and research activities.

Our Program

The Radiation Safety Officer assists the MBL research Community with the safe and compliant use of ionizing radiation including radioactive materials (RAM) and sealed sources, x-ray generating equipment and lasers.  The use of these materials and devices on MBL campus is regulated by the U.S. Nuclear Regulatory Commission (NRC), the Commonwealth of Massachusetts Department of Public Health and the federal Occupational Safety and Administration (OSHA).  We facilitate safe conditions for utilizing radiation in research and teaching, maintain radiation exposures As Low As Reasonably Achievable (ALARA), and ensure academic and research operations are conducted in compliance with applicable local, state and federal regulations.
