The following report was received from the
Nebraska Department of Health and Human Services via email:
The Nebraska Radioactive Materials Program was notified on January 4, 2023, about 1700 [CST] by a representative of Olsson of a damaged InstroTek, Model 3500, portable moisture density gauge. An Authorized User (AU) from Olsson transported the nuclear density gauge to a job site near Plattsmouth, NE for compaction testing on backfill for a new grain bin. Upon arrival at the site, he assessed the work area for hazards and began gauge standardization away from the active work area. During the standard count, the AU returned to his work truck to grab testing equipment which was approximately 100 feet east of where the gauge was sitting. During that time, the AU witnessed a contractor on site that was driving a tele-handler run over the gauge and standard block, causing damage to the gauge. Emergency procedures from Olsson's Radiation Safety Program were immediately reviewed and put into action by the AU. The local and Corporate RSOs [Radiation Safety Officers] were contacted to help with the situation. All personnel were removed from the area and the area was blocked out with emergency tape. The local RSO arrived with survey equipment, took readings around the area, made phone calls with the corporate RSO and manufacturer, and determined it was safe to transport the gauge back to Olsson's permanent storage location at the field office. The AU was wearing his dosimetry badge and he does not believe that any other individual on site would have received any exposure.
