| Title | Cs-137 Source Contained Within A Liquid Scintillation Counter Was Found To Be Leaking |
| Event Description | The following is taken from a facsimile received from Texas Department of Health [TDH], Bureau of Radiation Control:
Event Description: A 30 microcurie cesium-137 source located in a scintillation counter was found with 430,000 cpm counts on a swab leak test conducted by a serviceman. No contamination was found outside the source assembly. Texas Incident No. I-8024 The Licensee's report to TDH was also faxed to the NRC and is identified, in part, below: On December 3, 2003, the Radiological Safety Officer at Texas A&M University (TAMU) was notified by a service representative of Beckman Coulter that a Cs-137 source contained within a liquid scintillation counter was leaking. After obtaining information from the service representative, the RSO then made a telephone notification to the Texas Department of Health-Bureau of Radiation Control, informing Ms. Helen Watkins of the situation. This letter is a written notification of the leaking sealed source, in accordance with TAC 289.202 (ddd). The following information identifies the liquid scintillation counter and specifies of the source: Location: Chemistry Bldg., Room 2516 Manufacturer: Beckman S/N: 7060437 Source: Cs-137 Activity: 30 uCi [microcuries] The device user, a professor at TAMU, noticed that the device was not operating properly and contacted Beckman for service. The service representatives performed diagnostics on the device including a smear (cotton swab) of the plastic sphere source. The swab was counted with a result of approximately 430,000 cpm [counts per minute]. No parts have been removed from the device, but the intention is to replace the source, source housing, and source elevator. These components will then be returned to Beckman. Repair parts have been ordered. The device has been removed from service with signage indicating 'No Usage' and 'Contact Radiological Safety.' In addition, Environmental Health and Safety Department (EHSD) personnel performed contamination surveys on the device, the service representatives, and within the room. No contamination was detected. |
