Permit Changes

After the Radiation Safety Division has approved a Permit application and issued a Permit, any part of the Permit may be changed at any time.

The Permit Holder’s name, address, and contact information may be changed.

The following also may be added, changed, or deleted:

  • unsealed isotope approval and possession limit
  • room
  • associate user list
  • irradiator, nuclear gauge, ECD, x-ray producing equipment, or other sealed source

A change to isotope possession limits may often require a modification of the protocol to specify the requested change.

A Permit Holder may request a change to the Permit in a letter or by email.

The Permit Holder may also make direct change requests in the data-base, by accessing it directly.

The Radiation Safety Division may also generate a Permit change in response to:

  • the departure of a Permit Holder,
  • the transfer of a rad-type source,
  • an unsealed isotope inventory reaching the possession limit,
  • a change in room usage,
  • a request for dosimetry …

… and for other reasons.

All changes to the Permit are reviewed by the Radiation Division before approval.
