The following information was received from the
California Department of Public Health, Radiologic Health Branch via email:
On October 19, 2019, the RSO [Radiation Safety Officer] for APPlus RTD, USA, contacted the Radiologic Health Branch regarding a source disconnect event at the Phillips 66 Los Angeles refinery. The device was a INC Ir-100 exposure device (serial number not reported) with an INC Model 32 Ir-192 source (serial number and activity not reported). The disconnect occurred while the source was cranked out of the device for an exposure. After the disconnect was discovered, the radiographer stopped cranking the source, isolated the area and contacted the RSO about the incident. After arriving at the scene, the RSO and alternate RSO assessed the situation and then proceeded to return the source back into the exposure device. The licensee's investigation into this event is ongoing and will be reviewed further by the California Department of Public Health.
