The State of Washington Department of Health
(DOH) issues a Broad License to the University of Washington to
use radioactive material (RAM). It's the responsibility of the Radiation Safety Office
(RSO) to ensure that the license conditions are met.
All Authorized Investigators (AUIs)are responsible for ensuring that
radioactive materials(RAM)used in their labs are kept in a safe and secure location
when being stored or used. Prior to being authorized an AUI must demonstrate that
precautions have been taken to safeguard their RAM inventory.
Specific action to safeguard RAM may include:
- locks placed where RAM stock solutions are stored such as freezers,
refrigerators, and cabinets.
- locking laboratory spaces.
- written security guidelines for all lab workers.
- asking people entering the lab space for identification.
- never allow someone to borrow or take your RAM.
- put away all RAM when not in use
All AUIs using irradiators or high activity sources must have a plan approved by
Radiation Safety (RSO) that details how the source will be secured. These sources must
be in a locked room that is alarmed when not in use. Keys for the source must be kept
so that only personnel approved by the Radiation Safety Office have access to them. The source
may only be used when these approved personnel are present. Call Radiation Safety
at 206.543.0463 from 8 AM to 5 PM weekdays or by e-mail: firstname.lastname@example.org if you have any questions
Checking that your RAM is properly secured is an integral part of the survey
conducted by the RSO. If your lab is found to have RAM improperly secured the material may be
confiscated and depending on the severity of the occurrence, other actions such as
additional training or suspension of your authorization may occur.
Security is everyone's responsibility!! Keep all your RAM locked up when not in use!
Once an authorization has been written, it will
need to be maintained over time. For some amendments, writing a
memo describing the changes is sufficient.
Common amendments that require special forms
Use Application for Registration/Certification of Laboratory/Room for
Use of Radioactive Materials
(RSO Form 50) 04/07 to:
- Add a new laboratory to an authorization, or
- Change the use of radioactive material within a previously
RSO Form 50 can be filled in online then faxed or mailed. If you have PDF Writer or Professional
you can save the form & e-mail it to Radiation Safety.
An abbreviated version of this form, RSO Form
50R may be used to report a change of use in a
previously authorized lab.
Form RSO 50R, is not
currently available on the website because they are printed on
colored paper for filing purposes.
Both forms may be obtained by calling Radiation
Safety at 206.543.0463 from 8 AM to 5 PM Weekdays or by e-mail: email@example.com.
Use RSO Form 14 (Optional), "Amendment to Use
Additional Radionuclides" to:
- Add a radionuclide to an authorization or,
- Increase the authorized limit for a radionuclide.
The addition of radionuclides to or removal of
them from an authorization can also be accomplished by requesting
such action in a memo. Contact Radiation Safety by phone or e-mail:firstname.lastname@example.org for more
This form may be obtained in PDF format from this website, or can be
requested by calling Radiation Safety at 206.543.0463 from 8 AM

The License allows the RSO to issue
"authorizations" to investigators affiliated with the UW to
operate under the license. These people are called
Authorized Investigators (AUI) and are usually
faculty members or medical doctors.
The AUI is legally responsible for the handling
of radioactive material under their jurisdiction. The
authorization defines for the Investigator the following:
- which radionuclides may be used;
- allowable possession limit of each radionuclide;
- how the radionuclides may be used;
- which laboratories radioactive material may be used in;
- the required record keeping in the lab;
- any special conditions of the authorization;
- which lab personnel, called "radiation workers," may use
Use "Training and
Experience in Radiation Work" (RSO Form 20) to add a worker
to an authorization.
An individual must be listed on a RAM
authorization before it is legal for them to handle radioactive
material. This process makes them a "certified" radiation
Persons who will be in your laboratory for no
more than 3 months are
exempt from taking the formal Radiation Safety Training Class. However,
these individuals may handle radionuclides only under the direct
supervision of lab personnel or staff who are already certified for the
use of radioactive materials by the Radiation Safety Office.
It is recommended that persons who are planning on working with
radioactive materials should try to complete the training as soon as
possible after joining a laboratory.
Radiation Safety Training Class is offered ten times a year.
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
Use Radioactive Material (RAM)
Lab Personnel Change Form (Email Request) if you would like to terminate or remove
workers from your authorization. Only personnel changes can be made on this form;
i.e. lab terminations or additions, name or position (job title) changes or
moving to a different authorization
