| ENS 48273 | 24 July 2012 04:00:00 | Agreement State | Agreement State Report - Radiography Camera Source Disconnect | The following information was provided by the Ohio Bureau of Radiation Protection via e-mail: Licensee experienced a source disconnect with an industrial radiography camera. The radiographers were working at a temporary job site and attempted to retrieve source after completing the first exposure of the workday. Source would not retrieve and a source disconnect was suspected, with the source remaining at the exposure end of the guide tube. The source position was verified by on-site radiation surveys. The guide tube (containing the source at the far end) was disconnected from the camera and moved to an isolated location at the client site. The radiographers established appropriate barriers and entry controls for the temporary area and maintained constant surveillance until licensee's source retrieval personnel arrived. Retrieval personnel were able to reconnect the source using a special tool and the source was able to be retracted back into the camera. The camera and all associated equipment were sent to the manufacturer for evaluation. Cause of the problem was determined to be a worn connecting collar around the plug assembly and failure to follow a source connect procedure recommended by the manufacturer. Ohio Bureau of Radiation Protection will visit site and conduct an investigation. The licensee's report was received at Ohio Bureau of Radiation Protection today, 9/4/12, at approximately 1240 EDT. Based on manufacturer's evaluation of the equipment used, Ohio Bureau of Radiation Protection will conduct an investigation of licensee's maintenance program and to determine reasons for failure by licensee to make initial notification and follow-up written report in a timely manner. No significant personnel exposure was received during retrieval procedures. Ohio Report OH 120003 | ||
| ENS 42745 | 10 July 2006 01:50:00 | 10 CFR 30.50(b)(2) | Radiography Camera Source Unable to Retract | Acuren Inspection, Inc, a Texas corporation doing inspection work in Michigan, provided the following information via email: Description of Equipment Problem: The RT crew was using a 'pill stand' (a vertical metal pipe inserted into a coupling on a magnetic tripod with the source guide tube attached to a horizontal cross pipe) used to set up for an exposure. The 'pill stand' fell over during the exposure, thus crimping the source guide tube. Cause of Incident: The 'pill stand' was not stabilized on a flat and clean surface prior to exposure. Equipment: INC Exposure Device, Model IR-100, SN #4339, loaded with an 83 curie Iridium-192 source (Model 87703, SN #27923B). Place, Date, and Time of Incident: Filer City, Michigan, 8:50 PM CST, July 09,2006. The technicians tried to retract the source assembly into the exposure device, but could not get the drive cable to move either way. Lead blankets were placed over the collimator and part of the guide tube. The technician located the crimp in the source tube and cut approximately a 1 1/2 inch piece of source tube out and freed up the drive cable and slowly cranked the source back in slowly. At 3:10 am, the source was back in the camera. The three licensee technicians involved in the retrieval received 181 mR, 60 mR, and 95 mR respectively by pocket dosimeter. The RSO stated that results for July film badge readings for the technicians will be available in early August. The RSO also stated that there was no damage to the camera or source, and that the guide tube has been replaced. |
