| ENS 56461 | 24 March 2023 04:00:00 | Agreement State | Possible Overexposure Dose for an Embryo/Fetus of a Declared Pregnant Woman | The following was received from the South Carolina Department of Health and Environmental Control (the Department) via email: On 03/24/23, at 1446 (EDT), the Department was notified by the licensee of a dose more than the dose limit for an embryo/fetus of a declared pregnant woman. A written report was also submitted on 03/24/23. The employee is a Technical Assistant for mobile (positron emission tomography/computed tomography) (PET/CT) operations and is not directly involved with handling radioactive material. The estimated dose reported was 1145 mrem (deep dose equivalent) (DDE) for a one-month period, the cumulative dose was 1239 mrem DDE. The licensee's report indicated it is possible that the badge may have been in the PET/CT scanner room during patient scans, but the employee could not recall that this ever happened. The licensee also reported the chest and control badges showed no elevated readings; only the fetal badge. The licensee's corrective actions included discussing with the employee the importance of making sure the badge is never left in a radiation area, and while at work, the badge is always worn properly for the entire day. Proper storage of badges next to the control badge was also discussed. The Department performed an on-site investigation on 03/29/23, and the information obtained during the on-site investigation was consistent with the licensee's written report. This event is considered closed. South Carolina Department of Health and Environmental Control report no.: SC230008 |
