AGREEMENT STATE REPORT - POTENTIALLY DAMAGED GAUGE

The following information was provided by the Colorado Department of Public Health and Environment (the Division) via email:

"On Thursday February 1, 2024, at approximately 1030 MST, the Division was notified of a vehicle collision that resulted in the damage of a portable nuclear gauge (Nuclear Gauge - Troxler 3430 SN: 28355).

"The initial report indicated the Type A package containing the nuclear gauge was thrown from the vehicle and both the package and the gauge sustained damage.

"Colorado State Patrol responded to the scene and determined the nuclear gauge was intact, and it was turned over to the licensee.

"The Department confirmed with the licensee the gauge was able to be secured with the source in the shielded position and the shielding for the sources is not compromised. A leak test is being expedited at this time."
