The following is a summary of information … The following is a summary of information provided by the licensee via phone and email:</br>On December 18, 2025, at 1010 MST, a three-person crew was manipulating the digital radiology panel while setting up for their next shot. When the assistant attempted to push the lock slide on the camera, he noticed it was already in the unlocked position and realized the source was exposed. The crew did not hear their rate alarms activate. A survey was not performed at the time, as the survey meter was located at the cranks during the incident. Based on initial estimates, the crew was approximately one foot from the source. Work was stopped immediately. The licensee performed preliminary dose calculations assuming the crew was on the shielded side of the collimator for approximately 5 minutes at 1 foot, resulting in an estimated dose of 1.7 rem. All three film badges are currently en route for rush processing.</br>Camera Information:</br>Model - D8039</br>Source Serial Number: 24751P</br>Activity - 64 curies of Ir-192</br>* * * UPDATE ON 01/05/2026 AT 0859 EST FROM MATT KIM TO TENISHA MEADOWS * * *</br>The following is a summary of information provided by the licensee via email:</br>The post event evaluation consists of a review of written statements, interviews with personnel involved, and examination of the equipment used.
