EN Revision Text: AGREEMENT STATE REPORT - DAMAGE DENSITY GAUGE
The following information was provided by the Pennsylvania Bureau of Radiation Protection (the department) via email:
"On December 16, 2021, the licensee informed the department that a nuclear density gauge had been damaged at a job site. While a technician was carrying the Troxler gauge, they tripped and fell on top of the gauge handle. This broke off the handle about half-way from the top to the gauge. The portable gauge was a Troxler, 3400 series, Serial Number 15717, containing 8 millicuries of Cs-137 and 40 millicuries Am-241:Be. The area was secured, and the Radiation Safety Officer (RSO) called a third party (Applied Health Physics) for assistance. Applied Health Physics and the RSO determined that the source was secured in the shielded position, and gauge was not leaking. Applied Health Physics did site surveys and determined there was no dose to any employees or anyone on the job site. Applied Health Physics secured the handle to the gauge, and it was transported back to Construction Engineering Consultants, Inc. Pittsburgh office. Once at the office the gauge was placed in their office vault and has been taken out of service. It will be held there until it can be sent to the manufacturer for disposal. Applied Health Physics did a leak test on site that day and the sample results showed no evidence of radiological material. There was no exposure to workers or the public."

EN Revision Text: AGREEMENT STATE REPORT - RADIOGRAPHY DEVICE SAFETY LATCH FAILURE
The following information was received from the California Department of Public Health, Radiologic Health Branch (RHB) via email:
"On 12/17/2021, the licensee notified RHB of an incident in which an INC IR-100 (S/N 7362) radiography exposure device, containing a 54.2 Ci Ir-192 QSA Global source (S/N 55806M), failed to actuate its safety latch plate upon retracting the Ir-192 source to the fully shielded position. The incident occurred on 12/16/2021, at approximately 1900 PST, at the PBF refinery in Martinez, CA. The radiography site was approximately 150 ft. above grade, on temporary staging, and accessed by an adjacent permanent deck. The RSO [(radiation safety officer)] stated that the device was used all day without issue prior to the safety latch plate's actuation failure. The initial personnel during the incident consisted of a radiographer trainer and an assistant radiographer. The radiographer trainer noticed the failure when attempting to 'crank out' after fully retracting the source. After attempting to fully retract the source, the latch plate maintained a visibly depressed position and the source was not fully secured and free to move. The radiography trainer contacted the RSO for further assistance during which an additional radiographer trainer assisted with maintaining security of the barricaded area until the RSO and staff arrived on the site. The RSO stated that he was able to secure the source by flushing the locking mechanism with brake cleaner and that there was no excessive exposure to any personnel involved. RHB will be investigating this incident further."
