Brief Description of Incident:
Licensee's October Landauer [dosimetry processor] report reported a whole body exposure of 11,016 milliRem (Deep) and 10,465 milliRem (Shallow) to an individual who is a cyclotron operator. Landauer reported that this appears to have been a single exposure event, not a continuous exposure over the course of the month. Landauer is assessing the badge at this time to determine if it is a static or a dynamic exposure. The licensee reported a single contamination event that occurred 10/5/05 and resulted in skin and clothes contamination. The licensee is evaluating their documentation of this contamination event at this time. The licensee also reported that ring badges are exchanged weekly but that the badges in use during this contamination event are missing or have not been reported yet. The licensee reported that the individual in question was wearing an electronic dosimeter during the contamination event and recovery time span and had a recorded dose of 19 milliRem on 10/5/05. More information will follow as it becomes available.
Additional Notes:
Licensee reported a contamination event (details to be reported later) that occurred 10/5/05 resulting in contamination of the cyclotron operator's skin, clothes and lab coat. The individual left his/her badge on the lab coat overnight so the RAM on the lab coat could decay (110 min half life). Landauer reported the dose today (12/1/05) and has not evaluated if it is a static or dynamic exposure yet, but did report to the licensee that the reported dose appears to be from a single event. The individual who purportedly received this dose has been placed in non-RAM worker status.
