The following information was received from the
Texas Department of State Health Services (the Agency) via E-mail:
On April 12, 2022, the Agency received an email from a licensee regarding an Am-241 source that was no longer within the source holder of a Troxler Model 3430 (source assay date 9/29/1997 and serial 28367). The source capsule, source holder, and source cap were all loose within the gauge. This was the first notification to this Agency of this issue. The licensee reported that on March 25, 2022, a licensee technician reported measurement issues with this device. A survey of the device did not find any elevated readings. The device was pulled from service and inspected on March 30, 2022, at which point the loose components were discovered. This licensee had experience with this issue before (see EN 55774) and repaired the assembly using Loctite.
Licensee reports the source is not leaking and is secured within the source holder. Investigation is ongoing and additional information will be provided per SA-300.
