Title	Agreement State Report - Leaking Cs-137 Scintillation Counter Check Source
Event Description	Received the following information via fax: On April 2, 2009, [deleted] Radiation Safety and Control Services, a New Hampshire Health Physics company [located in Stratham, NH] reported that a Beckman scintillation counter (model 3801, # 7014048) owned by them is believed to have a leaking Cs-137 check source. The instrument was not operating properly. In December 2008, a technical support person was called, who determined the source was not reaching the sample. During an inspection of the source mechanism, a smear of the exposed spring that push[e]s the source revealed 500 cpm of removable contamination by direct frisk of the Q-tip. More smears were taken and two near the spring indicated 4,285 and 5,586 dpm beta when counted on a LSC on December 10, 2008. This LSC contains a 40 microCi cesium 137 check source, part number 598860, # 60219005-A originally dated August 18, 1986. The device was taken out of service immediately and labeled as internally contaminated. Follow-up with Beckman Instruments will take place regarding replacement of the source and decontamination efforts.
