| ENS 41522 | 23 March 2005 23:05:00 | On July 6, 2004, while performing routine QC tests prior to patient treatment, the High Dose Rate afterloading brachytherapy device (microSeletron-HDR) failed to retract. With Nucletron service personnel on the phone giving technical support, the RSO entered the room and manually retracted the 6.7 Ci of Ir- 192 source. His whole body exposure was subsequently found to be 7 mRem and ring badge <10 mRem. The device, which is manufactured by Nucletron, Inc, was found to have a defective "TU MPU PCB" board. After replacement and testing, the device was returned to operating status for future patient treatment. |
