Radiation Safety Training

This course is required for all personnel who wish to use Radioactive Materials at the University of Washington.


Individuals who have not yet completed the training may work under the direct supervision of laboratory personnel/staff who are already certified as Radiation Workers by the University of Washington Radiation Safety Office. The period of direct supervision may not exceed 90 days (three months).

This course is a series of four online modules covering basic radiation physics, the biological effects of ionizing radiation, laboratory radiation protection procedures, and radiation safety rules and regulations. Completion of the modules and the two hour in-person classroom training and final exam satisfy the basic training requirement for radiation workers as set forth in the University of Washington Radioactive Materials License.

IMPORTANT: ALL PERSONNEL TAKING THIS CLASS MUST REGISTER ONLINE.

This course does not meet the requirements for initial training required for all personnel who wish to use Radioactive Materials.

Call Radiation Safety at 206.543.0463 if you have any questions about this material.


This guidance and information is designed for personnel who do not work with radiation producing equipment or radioactive materials but by virtue of their duties may need to work near or around these areas. The information is recommended for ancillary personnel such as custodians, nursing staff, medical specialties, facilities staff, physical plant staff, and any non-radiation workers who may have occasional or infrequent duties around radiation sources.

It is the responsibility of the shop foreman, division or department manager, or supervisor to ensure personnel are provided this information prior to entering spaces where radioactive materials are used or stored. To assist in this training the above link provides on line information for all personnel. In addition a short training guide and/or brochure are available to provide this information to ancillary staff members

Radiation Safety Guide for Ancillary Personnel
Radiation Safety Brochure for Ancillary Personnel

The information provides basic knowledge of Radiation Safety terminology specific to the University of Washington and guidance when working around radioactive materials or radiation producing sources. The information fulfills our license requirements to provide a forum for Radiation Safety information to ancillary staff. Call Radiation Safety at 206.543.0463 if you have any questions about this material.



This is an online presentation designed for personnel who work with sealed sources of ionizing radiation. The information is recommended for persons who handle sealed and plated radioactive sources. Sealed and plated sources consist of radioactive material that is either encased in metal or plastic (sealed sources) or radioactive material that has been plated as a thin film onto metal or plastic (plated sources). The information provides basic knowledge of Radiation Safety procedures and terminology specific to the University of Washington. The presentation fulfills our license requirements to provide a forum for Radiation Safety information to personnel who use sealed sources. This training does not fulfill training requirements for persons who use open sources of radioactivity or high activity gamma irradiators. To become a research participant on a sealed source authorization, please contact the Radiation Safety Office at 206.543.0463 to begin this process.



This is an online presentation designed for nursing staff and other medical personnel who work with patients that are undergoing radiation therapy. It provides basic knowledge of Radiation Safety procedures and terminology specific to the University of Washington. The presentation fulfills our license requirements to provide a forum for Radiation Safety information to personnel who deal with patients who have permanent or temporary radioactive implants or are administered therapeutic quantities of radioactive materials.



This is an online presentation designed for dental personnel and other personnel who work with x-ray machines used for dental radiology. It provides basic knowledge of Radiation Safety procedures and terminology specific to the University of Washington. The presentation fulfills our license requirements to provide a forum for Radiation Safety information to personnel who work in and around areas where dental radiology is being conducted.



This video promotes Radiation Safety. Random primer labeling for southern hybridization is used to demonstrate the safety principles that apply to the use of radioisotopes in the modern biology laboratory. The video will introduce new staff to good laboratory practices and provide a meaningful technical review in safety for the more experienced laboratory worker.
