Emory University Health Physics Department received notification of a film badge reading with a Beta Dose Reading of 49919mR. This report is only preliminary at this point.
Period of exposure: 5/1/2008 to 5/31/2008
Deep Dose: 240 mR
Lens Dose: 240 mR
Beta Dose: 49919 mR
The assigned shallow dose was changed to 50,160 mrem due to the beta reading of 49,919 mrem. The other doses, including the ring badge reading, are not out of line with what she and her coworkers in PET-CT receive regularly.
[The employee] typically only works with [F-18]FDG [fleurodeoxyglucose]. These readings are consistent with a contaminated badge. I will confer with Landauer as to whether contamination with FDG might result in a reading like this, as I suspect.
The employee is currently vacationing out of the country and will return July 10, 2008. The investigation will be completed at that time.
