| Title | Radiography Camera Equipment Failure |
| Event Description | The following report was received from the California Department of Public Health (RHB) via email:
On 1/28/2022, the licensee notified RHB of an incident in which an INC IR-100 (S/N 4314) radiography exposure device, containing 92 Ci of Ir-192 QSA Global source (S/N 57551M), prematurely actuated its safety latch plate when retracting the Ir-192 source to the fully shielded position resulting in the source assembly stop ball being on the wrong side of the safety latch plate. The source assembly was eventually returned to the fully shielded position by the RSO [radiation safety officer]. The maximum dose recorded on the crews' pocket dosimeter was 7 mR. The incident occurred on 1/27/2022 at approximately 2100 PST at the MRC refinery in Martinez, CA. On 1/28/2022 licensee had taken the camera back to INC for evaluation. RHB will be investigating this incident further. California Event Number: 012822 |
