About Radiation Safety at WesternUradiation hazard sign

The radiation safety program of Western University of Health Sciences (WesternU) has been established to assist researchers to use small quantities of radioactive material in a safe and environmentally friendly manner. All individuals who utilize radioactive material at WesternU must be in compliance with the California radiation control regulations in Title 17 of the California Code of Regulations. In addition to the regulations, the University has been granted a radioactive material license from the State of California with limits on the amount of radioactivity that can be possessed on campus, and a number of special requirements that must be followed.

You must apply to use radioactive materials

Regulations require that WesternU have a Radiation Safety Committee to review and approve of the uses of radioactive material, procedures that faculty and students must follow in their research, and appropriate disposal of low-level radioactive waste. An annual review of the radiation safety program must also be conducted by the Radiation Safety Committee. Another requirement is that the University appoint a Radiation Safety Officer (RSO), named in the license, to manage the radiation safety program and provide leadership and oversight to all laboratory personnel approved to use radioisotopes. The present RSO is Donald E. Walters, PhD  (dewalters@westernu.edu), Director, Office of Research Regulatory Affairs, Office of the VP for Research.

Start the application process

To initiate the use of radioactive materials in research, a Statement of Training and Experience must be submitted to the RSO. Clicking on the link below will take you to the form.

 Statement of Training and Experience

 The RSO must submit this form to the Department of Public Health to add the investigator’s name to the Radioactive Material License. The approval process by the State of California can take several months so early submission is encouraged.

*At this time, the COMP Northwest campus in Lebanon, Oregon, is not approved for use of radioactive materials.


In addition, a new user must successfully complete WesternU’s on-line Radiation Safety Course (on Blackboard) that consists of a video and an associated quiz.  You must score 100% on the quiz to receive credit for this training.

The quizzes may be taken as often as necessary to achieve this score. The Radiation Safety Course may be accessed in the Faculty and Staff Training Center by clicking on Blackboard. Once there, you will need a user name and password to enter the site. After you are in, click on Faculty and Staff Training Center from the list of courses on the right hand side of the screen. After accessing the Training Center, click on Lab and Radiation Safety and then click Radiation Safety. If you need assistance, contact tech support at 469-5432; techsupport@westernu.edu.
