The following information was received froThe following information was received from the California Department of Public Health, Radiologic Health Branch (RHB) via email:</br>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.</br>California 5010 Number: 021926 personnel.
