If an authorized PI no longer needs to use radioactive material, they may request to become inactive. Doing so eliminates the need for contamination surveys, inspection visits, inventory management, etc. When inactivated, all remaining radioactive material and radioactive waste will need to be removed from the lab. The Radiation Safety Office may store some long half-life sources on request. Inactive projects may be re-activated without a new proposal submission.
Alternatively, if the PI believes they will not need to use radioactive material in the future, the authorization may be cancelled. Doing so will allow the removal of all radioactive posters, radiation measuring devices and the requirement for radiation training. In this case, a re-activation would require a new proposal submission.
