Radiation Safety Training Courses

Research: Worksafe – RAM, Diff/Fluor X-Ray, LINAC, Cabinet x-ray, Refreshers, etc.
For Clinical Training: UCLA Health Safety Training

Individuals who directly handle radioactive material or radiation-producing machines are referred to as occupational radiation workers and are required to complete radiation safety training. EH&S provides initial radiation safety training courses that introduce basic radiation safety principles, techniques, and requirements along with supplemental documents containing relevant safety and compliance information. 

Users of radioactive materials will be required to take the online course, then attend a classroom session. Only those who successfully complete both parts will be permitted to work with radioactive material. 

Users of radiation-producing machines will be required to take the online course. Only those who successfully pass the course will be permitted to work with radiation-producing machines. Users of higher risk radiation-producing machines, such as LINACs and X-ray irradiators, require additional training.

This learning track is designed to educate personnel on proper work procedures and safety guidelines for work with radioisotopes in a research or clinical environment. Participants first pass an online course, then attend a classroom session presented by EH&S Radiation Safety staff. Both must be taken by first-time radiation workers. After that, refresher training is required annually and as needed.

  1. Complete the online course, Radiation Safety Fundamentals (Radioactive Materials) (2026). Course code: RAD-RAM1-OL.
  2. Attend the classroom training session, Radiation Safety for Materials Users – In-Class. Course code: RAD-RAM2.
  3. Refresher training is required every year: Radiation Safety Refresher (Radioactive Materials) (2026). Course code: 000056

Linear accelerator and X-ray irradiator users should contact Radiation Safety for additional requirements in addition to the below training.

Complete the online course, Radiation Safety Initial (Radiation Producing Machines) (2026). Course code: RAD-RPM-OL

This course provides an overview of hazards related to working with radiation-producing machines and safety precautions. This course meets Cal/OSHA regulations (Reference: 17 CCR 30255(b)). 

Refresher training is required every year: Annual Refresher Training for X-Ray Users. Course code: RAD-XRAY-OR-V2

NOTE: The refresher course is not required for irradiator users, who, instead, are required to take device-specific irradiator training annually.

Minimum Frequency: Annual

Radiation Safety For Users of X-RAY Irradiators

Minimum Frequency: Triennial

Shipping of Radiological Materials Training - Worksafe Course ID: RAD-SHIP-OL
