Title	Leaking Sealed Source
Event Description	The following information was provided by the Florida Bureau of Radiation Control (BRC) via email: On 3/27/24, the Cs-137 dose calibrator source was found to have 635 disintegrations per minutes (dpm) of contamination during the routine weekly swipe. Second set of swipes found 2346 dpm on the inside of the shielded container and 2559 dpm on the outside of the vial. The source was cleaned and swiped again, which brought counts to zero on the inside of the shielded container and 1018 dpm on the outside of the vial. On 4/1/2024, the swipes were counted again and found to be at the same level, showing the contamination to be a long-lived isotope. Since the area where the sealed source resides does not contain long-lived isotopes, it was assumed the source was leaking and was taken out of service and stored under the office of radiation safety's control. On 4/2/2024, Eckert and Ziegler [the manufacturer] was contacted to request instructions on returning the leaking source. Another swipe taken on 7/29/2024 found 17807 dpm and a small fracture was noticed on the vial. This swipe exceeded 5 nano Ci, and the report was made to BRC. Source will be returned to the manufacturer. Source Information: Manufacturer: Eckert and Ziegler. Model: RV-137-200U. Serial number: 1047-67-4. Original activity: 197 micro Ci with a calibration date of 7/1/2004. Florida Incident No.: FL24-076
