Updated: May 2023

Radiation safety training requirements apply to all persons from the authorized users list including the radiation permit holders.

All radiation training courses (in class and online), are:

  1. valid for 3 years
  2. accompanied by a test with the passing mark 70%.

Radiation Safety-Theory is required to be taken by a person working with open sources who was not previously trained in radiation safety at the University of Toronto. It covers the basics of ionizing radiation, interaction of radiation with matter, biological effects and instruments used to measure radiation.

The Radiation Safety-Theory is offered as: a) online course (EHS716) and b) in-class (EHS717). Both courses are equivalent and only one of them is necessary.

Radiation Safety-Policies and Procedures is mandatory for a person working with open sources who was not previously trained in radiation safety at the University of Toronto. It is offered only in-class and the completion of the Theory part is a pre-requisite. It contains: laboratory work practices, emergency preparedness and examples of calculations and direct monitoring.

The Radiation Refresher (online) course must be taken by every person working with radioactive open sources every 3 years.

The Sealed Sources Safety (online) is required to be taken by persons working with sealed source only.

The Sealed Sources Refresher (online) must be taken by all persons kept on the list of the authorized users of sealed sources every 3 years.

The Radiation Safety – Project Students  (online) is required for people that will work, for a short time and under supervision, at a radioactive lab.

Introduction to Radiation Protection (online) is a course for U of T personnel that need to work outside the U of T at a nuclear facility for research or interdisciplinary project. The course is not valid to use radioactive material at the U of T.

All Irradiator Users must have the Sealed Sources Radiation training valid. For specific work training with irradiators and for obtaining access to the irradiator rooms, the users must contact Daniel Cardenas (daniel.cardenas@utoronto.ca).
