Frequently Asked Questions

Can I work with radioactivity before taking the radiation safety Training?

Yes, students may register under a Radioactive Permit and work with radioactivity before taking the in-class Radiation Safety Training. To register, the New User registration form must be completed and signed by the Radioactive Permit holder. Completion of the New User registration form also has a practical training component and the Permit Holder or a knowledgeable user must provide instruction to new users on how to safely use radioactivity in their lab.
