| Title | Potential Overexposure |
| Event Description | The following is a summary of information provided by the Arkansas Department of Health (the Department) via email:
During a routine inspection on October 21, 2025, the Department was made aware that on two separate occasions, the production manager had performed repairs on the production line of F-18 fluorodeoxyglucose (FDG) without wearing dosimetry. On Tuesday, October 28, 2025, inspectors from the Department were following up on the concerns and confirmed that on one occasion, the production manager was not wearing dosimetry during the replacement of tubing on a cracked line inside a production hot cell. This repair was conducted along a 25.4 cm (10 inches) tubing line with one end being 10 cm (3.9 inches) from the source vial of F-18. The activity of the source was 118.4 GBq (3.2 Ci) as per the radiation safety officer (RSO). Re-enactment of the procedure was produced with the production manager to reconstruct similar parameters. The RSO initially was not made aware of the individual not wearing dosimetry. Dose estimation is currently being conducted by the RSO and by the Department. The licensee will also have an independent contractor perform a dose calculation for the event that was conducted without dosimetry. While dose estimations are being calculated, the Department believes it has enough information to determine that this event threatens to cause an extremity exposure greater than or equal to 250 rads, and thus, are reporting immediately to the NRC in accordance with SA-300. This investigation is ongoing and updates will be provided. Arkansas Event Number: ARK-2025-014 |
