| Title | Leaking Source |
| Event Description | The following information was obtained from the Ohio Bureau of Radiological Protection via email:
On 2/17/2023, the licensee's [Alternate Radiation Safety Officer] ARSO entered the radioactive material storage room where a technician was opening the housing on a device containing a Kr-85 source. Upon the initial attempt to withdraw a bolt of the device housing, an area radiation monitor began to alarm. The ARSO and the technician took a second reading with a Victoreen 451 [radiation detector] to confirm that it was Kr-85 gas leakage and exited the room. A radiation survey meter indicated that there was no contamination on either person. Removable swipes of the area outside of the room also were indicative of no contamination. The entry door was sealed and access restricted until additional information was available. Follow-up entries were completed by the ARSO on 2/20/2023 and 2/21/2023 using 1 meter by 1 meter grids to identify specific areas of testing for removable contamination. Radiation and contamination survey results identified no readings above background. The licensee did not report results of any personnel testing or estimates of uptake. The licensee is investigating the cause of the Kr-85 leak. [Ohio Department of Health] ODH will travel to the site to conduct an investigation on 02/28/2023. Ohio Item Number: OH230003 |
