Radiation Training

Radiation Training

Individuals who want to use radioactive materials, lasers, or irradiators are required to take Harvard-specific training before working with the radiation sources (radioactive materials, lasers, and X-ray devices). All training can be completed online through the Harvard Training Portal.

Radioactive Materials

Radioactive materials users need to complete online Radioactive Materials Safety training before using radioactive materials. Online refresher training is required every two years.

Those who desire access to an irradiator need to follow the Irradiator Access-Approval Process.


Use of a Class 3B or 4 laser requires completion of the Radiation Protection Office Laser Safety training before using a laser. Laser training is refreshed every two years. Users may choose to complete a laser pre-assignment eye exam (not required) prior to laser use (according to the laser pre-assignment eye exam instructions).

Lab-Made Laser Microscopes

Users of a lab-made microscope need to complete the full Radiation Protection Office Laser Safety training.

Commercially-Made Laser Microscopes

When using an unmodified commercially-manufactured laser microscope, users must complete the online Commercial Laser Microscope Safety training. However, if you service or adjust the laser of a commercial microscope or use a lab-made microscope, you will need to complete the full laser safety requirements.

X-Ray Devices

All X-Ray users need to complete online X-Ray Safety training before using X-Rays. Feel free to contact the Radiation Protection Office if you have questions about your specific setup.

Online Training

Users must have a HarvardKey to access the Harvard Training Portal. Instructions for activating your HarvardKey can be found through the EH&S Traning Program.

Users who have already claimed their HarvardKey should log into the Harvard Training Portal to complete web-based training or view classroom training schedules.

If you have questions, please call the Radiation Protection Office at by calling 617-496-3797 or emailing radiation_protection@harvard.edu.
