Radiation Safety Training

If you know exactly which course(s) you are required to complete:

Please go to My EHS Training webpage, read the information on it and Log-in (bottom of the page) to register for the course

If you are not sure of the course(s) you are required to complete:

Please visit the EHS training matrix webpage to find the courses offered by the Radiation Protection Service (and other EHS courses)

Laboratory Personnel Training Matrix

Click the appropriate check box/boxes for the hazard/s connected to your research work (radiation, lasers, X-ray, etc.). If more checkboxes appear, click the one/ones that better describe your research work. Once you are done, you can choose to download the table as a pdf (“Download a PDF” button below the table) or directly register for the course/s (“Log into My EHS Training” button at the end of the webpage).

A more in-depth presentation of the radiation safety theory can be found in the Radiation Safety Training Manual.
