EN Revision Text: POSSIBLE OVEREXPOSURE

The following is a summary of information provided by the licensee via phone and email:

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.

Camera Information:
Model - D8039

AGREEMENT STATE REPORT - STUCK SHUTTER

The following is a summary of information provided by the New Mexico Environment Department via email:

On December 29, 2025, at approximately 1030 MST, while attempting to free a shutter that had difficulty moving during an inspection, the shutter mechanism broke. The shutter is currently stuck open in its normal operating configuration on a pipeline. The source is a Berthold cesium-137, 30 mCi, model P-2623-100 in a Berthold model LB7440 holder. Radiation Technology, Inc., has been contacted for radiation support. They are scheduled to come to the site in January and plan on either replacing or fixing the shutter mechanism at that time. This repair or replacement should be completed no later than January 31, 2026.
