| Title | Agreement State - Moisture Density Gauge Source Rod Stuck Open |
| Event Description | The Illinois Emergency Management Agency (the Agency) provided the following information via phone and email:
Weaver Consultants Group North Centra, LLC (the licensee) notified the Agency of a source rod stuck open on a Troxler 3440 portable density gauge (8 mCi Cs-137, 40 mCi Am-241/Be). The licensee confirmed that the incident took place on August 27, 2024. The source rod was stuck out 3 inches. The [licensee's] consultant came to the jobsite to pick up the gauge for repair the same day. The consultant confirmed that they were able to retract the rod once back at their facility. The gauge is pending repair. Agency staff will be on-site August 28, 2024, to perform a reactionary inspection. Updates will be provided as they become available. Illinois Item Number: IL240019
The following is a summary of information provided by the Illinois Emergency Management Agency (the Agency) via email: Agency staff conducted a reactive inspection at the site where the gauge failed to function as designed on August 28, 2024. Gauge use was observed and the gauge user was interviewed. It is believed the compacted clay hardened and prohibited retraction of the source rod. Inspection and repair by the licensed consultant evidenced no damage or obvious defects. Notification was timely and a proper written report was received. No occupational or public exposures are anticipated from this incident. Barring any further developments, this matter is considered closed. Notified R3DO (Hills) and NMSS (email). |
