The following information was received via E-mail:
On 1/4/2021, a leak test was performed on an Isotope Products Laboratories Cs-137 sealed source vial, serial number 1074-19-20, used as a dose calibrator constancy source. The current calculated activity at the time of the leak test measured 147.49 microcuries from the reference date of 9/1/2004. The measured results of the leak test revealed an activity of 0.012 microcuries on 1/4/2021 at 1253 EST.
The Cs-137 sealed source was promptly sealed within its lead container and firmly taped closed. This taped pig was then placed inside of several nitrile gloves, which were also generously taped closed, adorned with radioactive material stickers and the source was placed into the facility's radioactive material waste storage closet. The visible label includes the isotope, date of storage, current activity, and signature of the individual who stored it. The same documentation was also entered into the sealed source inventory. The RSO was then promptly notified of the event.
The source leak test was conducted by Alliance Medical Physics.
