| ENS 44233 | 21 May 2008 04:00:00 | Agreement State | Agreement State Report - Leaking Check Source | The State provided the following information via email: Licensee identified a leaking sealed radioactive source. Once identified, the source was taken out of service and placed in the licensee's waste stream and a contamination survey of the area was made. No measurable contamination was identified from this survey. Contamination wipes consisted of area wipes (filter paper) measured in a liquid scintillation counter. The Cs-137 source was used to test the response and functionality of hand-held radiation detectors. The leaking source, S/N 189-26-5, is a Cs-137 check source with an activity of 100 uCi on 3-1-87 and was manufactured by Isotope Products. The licensee stated the source may not meet the regulatory criteria for a sealed source since the front of the source is electroplated to allow for the detection of Cs-137 betas. As a precaution, the licensee reported it as a leaking source. |
