Radiation Safety Training

During the Pandemic

Please complete all online training during the pandemic. 

Now holding instructor-led classes "Radiation Worker Training - Part II". Please follow the registration instructions below. Only three students can take the exam at once at the EHS Support Facility. Instruction on zoom.

The Radiation Safety Training Manual is available as a study guide to prepare for Radiation Safety Initial Training, Rad Worker Training - Part II, and PI RAM Module. 

Worker and PI Training Information


Two-part training is required to obtain Radiation Worker certification:

  • CU: Radiation Safety Initial Training (Part I), in Skillsoft
  • Radiation Worker Training - Part II, in person

It is highly recommended to complete this two-part sequentially.

To maintain Radiation Worker certification, the Radiation Safety Refresher training must be completed annually in Skillsoft.

Radiation Worker Training

CU: Radiation Safety Initial Training (Part I)

The course covers basic radiation physics, instrumentation, biological effects of ionizing radiation, radiation protection principles and radioactive waste, among other topics.

Radiation Worker Training - Part II

This is an instructor-led training, offered monthly, reviewing topics from the initial training, plus use and selection of instrumentation, radioactivity calculations, and decay concept. An overview of RAM use in the lab setting is discussed, as well as recommendations for record-keeping.

Currently offered sessions:

10/26/2021, Tuesday, 9:00-10:00AM, zoom-class, followed by (~1hr) exam at EHS Support Facility (on-campus).

  • if your registration confirmation email states you are "WaitListed", the session may already be at capacity. You will be contacted if a space opens. 

To prepare for Radiation Worker Training - Part II:

  • Attendees must bring a scientific calculator to the class
  • Review of the Radiation Safety Manual prior to the exam
  • The attendee must reserve enough time in their schedule to complete the exam 

RAM PI Module    

PIs seeking authorization to use radioactive material must complete this training, included in the latter part of the instructor-led Radiation Worker Training - Part II.

Radiation Safety Refresher Training

This Skillsoft course covers radiation safety principles, and serves as a reminder on best practices and radiation safety processes and procedures.
