On February 23, 2026, at 1731 CST, BRC was notified by the licensee's radiation safety officer (RSO) of a damaged moisture density gauge incident. An in-use Troxler soil moisture density gauge model 3430 was run over by a bulldozer at the construction site of a new apartment complex located in Pensacola, FL.

The RSO states that the area has been cordoned off and on-site personnel are ensuring that no one approaches the area until he arrives. The gauge was run over while the rod was deployed. The entire apparatus is crushed flat with the level of the ground.

Personnel from the BRC are responding to the site, and a report update is anticipated.

AGREEMENT STATE REPORT - FOUND SOURCE

The following information was received from the California Department of Public Health, Radiologic Health Branch (RHB) via email:

"On February 24, 2026, a truck trailer that had triggered the radiation alarm at the WM-Azusa Special Waste Services (Azusa Landfill) on February 19, was dumped to allow Los Angeles County Public Health Radiation Management personnel to search for a suspected Ra-226 source in a load of waste glass fragment material based on RHB Identifier R400 identification of Ra-226. The search did not find an intact Ra-226 source as expected. Instead, the search found fragments of Ra-226 in a portion of the dumped load. Since the recovered Ra-226 material appears to have significantly exceeded 1000 times the Part 20, Appendix C value, RHB is reporting this discovery. The RHB will be visiting the glass recycling company in an attempt to determine the origin of the Ra-226 material and any potential significant exposures to personnel of the glass recycling company (Strategic Materials, Inc), the truck driver, and landfill personnel."
