Using radiation like radioactive materials, lasers, or X-rays at Harvard is managed using a radioactive use permit issued by the Radiation Safety Committee (RSC), in accordance with our radioactive materials license or other regulations issued by the Massachusetts Department of Public Health's Radiation Control Program.

Approved applications are valid for two years. Don't use radioactive materials, devices, or lasers at Harvard without a valid permit.

To apply for a permit, download and complete a radioactive materials and devices or laser/non-ionizing permit application. Return the application to EH&S by either:

• Mail: 46 Blackstone Street, Cambridge, MA 02139)
• Fax: 617-496-5509
• Email: radiation_protection@harvard.edu

A health physicist meets with the faculty member to review your application, discuss the experiment's radiation safety, and assist with lab set up. Faculty members are primarily responsible for radiation safety in facilities under their control. EH&S makes recommendations to the RSC, which votes by either a mail ballot or at the next regularly scheduled meeting.
