Industrial radiography source exchange: a project checklist
Use this checklist to schedule, document, and close out an Ir-192 or Co-60 source exchange without regulator surprises.
Source exchanges are routine but easy to mishandle. This checklist captures the steps where projects most often go sideways.
Before the exchange.Confirm the source exchange vendor's license includes both the new source delivery and the old source removal. Schedule shipping coordination at least four weeks ahead — manufacturer lead times for new sources are not what they used to be. Confirm your radiographer training records are current. Pre-notify the state if your license requires it.
Day of exchange.Document the old source serial number, activity at exchange, and date. Document the new source serial number, activity, and date. Take a wipe test of the new source and the camera. Update the source inventory in the same business day.
After the exchange.File the source exchange documentation with your license file. Update the next leak test schedule. Confirm the disposal pathway documentation for the old source — your vendor should provide a manifest. Bill back to the right cost center.
Where it goes wrong.The most common failure mode is the new source arriving before the old source has departed, leaving the facility temporarily in possession of two sources when the license authorizes only one. This is a violation. Coordinate dates carefully.
