Title	Agreement State - Lost Iodine-129 Calibration Source
Event Description	The following report was received from the Colorado Department of Public Health and Environment via facsimile: The Colorado Department of Public Health and Environment received telephone notification of a lost Iodine-129 sealed source (~24.8 microCuries; Assay date: 6/1/1992) on 8/29/2011 at approximately 4:00 p.m. The University of Colorado, a research licensee, reported that a campus inspection conducted on 8/12/2011 identified a missing gamma counter calibration source. As of 8/29/2011, all efforts to locate the source have failed. It is suspected that the source was discarded with an entire sample rack that was removed from the counter for disposal at some time within the last six months. The source was used for reference in a gamma counter and was an epoxy sealed type source with a small vial geometry. The licensee will submit a written report with more detail within the next few days. No other details are available at this time. Colorado Report: CO11-I11-13
