To register for any of these courses, go to My EHS Training, Log-in (bottom of the page) and look for the course code.

The Radiation Safety is be divided into two parts: Radiation Safety-Theory and Radiation Safety-Policies and Procedures

The Radiation Safety-Theory course will be offered as:

      1. Online   – course number EHS716 or
      2. In-person – course number EHS717

The applicant can choose between the two versions of the theory training.

The Radiation Safety–Theory must be followed by the Radiation Safety–Policies and Procedures (EHS718) which is offered only in-person. The completion of the Theory part is a prerequisite for the Policies and Procedures part.

EHS718 consists of radiation hazard presentation, practical sessions, emergency preparations and a quiz.
