On the night of 8/28- 8/29/2006 the large irradiator was being used for an all night procedure. The principle investigator for the irradiator was present to conclude the operation on the morning of August 29. At the time designated for source retraction, the irradiator source in fact did not retract to the stowed position. The source actuation system uses air pressure to expose the source and spring force to stow the source. The principle investigator tried to house the source by operating the "override" button. The source remained exposed. After approximately 15 minutes the source returned to the housed condition with no operator action. The irradiator will not be used until J.L. Shepard (the manufacturer) is contacted and the cause identified and corrected. The source is currently stowed. The irradiator is an 8800 Curie Cs-137 self shielded irradiator. Iowa event number I806004 The state notified Region 3 (Lynch).
