Radioisotope Authorizations

A Principal Investigator who plans to possess or use radioactive materials in any form at Princeton University must apply to the Radiation Safety Committee to obtain a Radioisotope Authorization. The Authorization specifies the radioisotopes the PI is permitted to use, the authorized chemical and physical form for those radioisotopes, the possession limits for each radioisotope, the authorized location of radioisotope use, and the authorized experimental protocol(s). Each Radioisotope Authorization is issued for a five-year term and must be renewed prior to its expiration. The application and approval process are described below:


Initial Application (top)

The first time that a Principal Investigator applies for a radioisotope authorization at Princeton University, he or she must submit a more extensive Radioisotope Authorization Application than will be necessary for subsequent applications:

Contact Sue Dupre to request the electronic application form.

The PI should be aware that the entire authorization review and approval process may take as long as 3-4 weeks and may take longer for non-routine proposals, although the RSO may grant a 30-day temporary authorization under certain conditions.


Subsequent Applications (top)

An Authorized User with current authorizations who wants to become authorized for additional radioisotopes must submit a new authorization application. However, the amount of paperwork is not as extensive as the original application.

Contact Sue Dupre to request the electronic application form.


Authorization Process (top)

1. When a Principal Investigator applies for radioisotope authorization, he or she must submit a copy of the Radioisotope Authorization forms described above for Initial and Subsequent Applications. Although a separate Authorization Number is issued for each radioisotope the PI intends to use, the PI may use one application form for all the radioisotopes of interest. The PI is encouraged to contact the RSO with any questions concerning completing the forms.

2. The PI must sign the forms, and the main Radioisotope Authorization Application must also be signed by the Departmental Safety Manager.

3. The completed, signed forms are mailed back through campus mail to EHS.

4. After EHS receives the forms, the RSO will review the application and will contact the PI to schedule a meeting to review the application and to review the requirements of the Princeton University radiation safety program. This meeting may take as long as 2 hours. In addition to this interview, the PI must complete the Princeton University radiation safety training program at the earliest possible opportunity, even though the PI may have attended radiation safety training at other institutions and may be an experienced radioisotope user.

5. After the authorization review meeting, the RSO will pass the application on to the Radiation Safety Committee, along with the RSO’s recommendations regarding approval or disapproval of the application. Once it receives the application, the Committee has two weeks to review the application and to act on the application.

6. The PI should be aware that the entire authorization review and approval process may take as long as 3-4 weeks and may take longer for non-routine proposals.

7. After the RSO receives notice that the application has been approved, s/he will send written notification to the PI that the application has been approved. As part of this notification, the PI is provided with a copy of a Radioisotope Authorization that specifies the radioisotopes that may be used, the possession limits that apply to each radioisotope, the location(s) in which radioisotope use may occur and any conditions that have been imposed on the PI’s use of radioactive materials. Radioactive materials may not be ordered until the formal Radioisotope Authorization has been issued.

8. Authorizations are issued for five-year periods and must be renewed at the end of the authorization period.


Amending an Authorization (top)

An Authorized User must apply for an amendment to his or her authorizations if any of the following circumstances:

  • To add or delete an authorized location for radioisotope use
  • To increase or decrease the authorized possession limit
  • To amend the authorized chemical or physical form
  • To amend the authorized experimental protocol or to add a new experimental protocol
  • To amend the experimental protocol to allow the in vivo or in vitro use of radioactivity in animals

Application for Authorization Amendment: (Word or pdf)


Inactivating an Authorization (top)

An Authorized User who does not plan to use radioactive materials for a year or more may find it worthwhile to apply to inactivate his or her authorizations. For the duration of the inactivation, the Authorized User is not required to submit routine reports, lab personnel are not generally required to attend initial or refresher radiation safety training, and EHS will not visit the lab to perform routine contamination surveys. EHS will not approve radioisotope purchases for inactivated authorizations.

Application to Inactivate An Authorization: (Word or pdf)


Canceling an Authorization (top)

An Authorized User who does not plan to use radioactive materials under an authorization any longer or who plans to leave Princeton University must submit an application to cancel his or her authorizations. Before submitting the application, the Authorized User must either make arrangements to dispose of all radioactive materials as waste or must make arrangements to transfer the materials to another Authorized User.

Application to Cancel An Authorization: (Word or pdf)
