Title	Lost Source from a Level Measuring Device
Event Description	Licensee reported that two 50 millicurie Cs-137 sources, used in level measuring devices, were found to be missing from a magnesium oxide producing facility that had been closed for two years. It was determined that two sources were missing after a review of their registration around the April-May time period. Since then, they located one of the two sources, brand new, in a crate on a shelf at the facility. They located the non-nuclear part of the device (the receiver) on a hopper which was at a scrap yard on site, but the sending unit (the nuclear part) was missing. They continued looking for the sender, but could not find it. * * UPDATE ON 07/27/05 @ 1745 BY ASHLEY TULL TO CHAUNCEY GOULD * * * The single source which is still lost is a TN Technologies Model 5200 gauge containing 200 millicuries Cs-137 not 50 millicuries. Notified Reg 3 RDO (Mark Ring) and NMSS EO (Joe Giitter) * * UPDATE ON 07/27/05 @ 2142 BY JOHN CROOKS TO CHAUNCEY GOULD * * * Two NRC Inspectors visited the closed facility with a radiation detector and located the missing device in a parts warehouse at the facility. It was on a shelf and had turned rusty and was unidentifiable. The device was isolated in another building with the other device that had been found. Notified Reg 3 RDO (Mark Ring), NMSS EO (Joe Giitter) and TAS(E-MAIL)
