| ENS 57015 | 6 March 2024 06:00:00 | Agreement State | Source Disconnect | The following is a synopsis of information received via email from the Alabama Department of Public Health, Office of Radiation Control: On the evening of March 6, 2024, the licensee experienced a source disconnect at a job site in Russellville, Alabama. The source connector appeared to have not been connected properly, and the source apparently disconnected from the drive cable while outside the exposure device (camera). The source was retrieved and secured in a 650L model source changer about 45 minutes later when a source retrieval team arrived on site. The two source retrieval personnel received 45 milliroentgens and 15 milliroentgens of exposure respectively. The radiography crew dosimetry had not yet been retrieved for emergency processing at the time of the report. The camera and source information is as follows: Sentinel 880D, D1120, about 78.9 curies of iridium-192 in a model A424-9 source. Alabama Incident Number: TBD | ||
| ENS 51779 | 7 March 2016 04:33:00 | Agreement State | Agreement State Report - Unable to Retract Radiography Camera Source | The following report was received from the State of Mississippi via facsimile: The Licensee notified DRH (Mississippi Department of Radiation Health) on 3/7/2016, that an incident had occurred at 2233 (CST on 3/6/16), at the client's site (in Holly Springs, MS). The Licensee's two (2) man radiography crew was performing radiography inside a twelve (12) foot, open end vessel, thirty six (36) feet long, and nine (9) foot off the ground. The radiography camera in use was a Sentinel model 880D, serial No. D1120. During one exposure the guide tube became crimped preventing the source from retracting back into the camera. This was due to the camera falling off the scaffolding to the vessel floor while the radiographer was retracting the source. The resulting action caused the guide tube connected to the camera and magnetic stand to become crimped at the camera connection point. The licensee's radiography supervisor was notified and the restricted area boundary was increased by the two (2) radiographers. Source retrieval was performed by the radiography supervisor with assistance from the radiography crew. A survey was performed using a NDS, ND-2000, SN: 20113, Calibration date: 1/15/2016, at the opposite end of the vessel thirty two (32) feet away from the source revealing a reading of two hundred twenty (220) mR/hr. A decision was made to pull the camera to one opening of the vessel by the camera cranks. The restricted area was then readjusted for two (2) mR/hr. While the camera was being lowered to the ground with a guide rope out of the vessel opening, the guide tube became straight enough to allow for source retraction. The guide tube and magnetic stand hung at the opening of the vessel causing the guide tube to straighten out from the weight of the camera below the vessel opening. The radiographers made another attempt to retract the source with success when the guide tube was straight. Once the camera was on the ground, the Licensee's survey of 46 mR/hr confirmed the source was retracted back into the camera. Doses to the radiography crew and supervisor were all below 60 millirems (mR). Instadose radiation badges were used with the highest dose reported of thirty nine (39) mR to both radiographers. Pocket dosimeters were also used with the highest dose reported by the radiography supervisor of fifty five (55) mR. Licensee's written report was received on 3/7/2016. The camera has been removed from service pending a sealed source and DU wipe test. Implemented corrective actions included adequate lighting at night and tying the camera off when it is used over twelve (12) inches off the ground. The radiography camera contains a 79.9 Ci Ir-192 Source, model A424-9, serial number 28799G. The State of Mississippi instructed the licensee to submit a 30 day written report and considers this case to be closed. Mississippi State Report number: MS-16002. | ||
| ENS 48244 | 26 August 2012 05:00:00 | Agreement State | Mississippi Agreement State Report - Radiography Truck Involved in an Accident | The following information was obtained from the state of Mississippi via email: DRH (Mississippi Division of Radiation Health) was notified 8/26/2012 by MEMA, Mississippi Emergency Management Agency, regarding an overturned radiography truck that occurred on Hwy 45 south of Macon, Mississippi. Two Licensee personnel were involved in the wreck with minimal injuries. The camera remained secured in the overpack but separated from the destroyed dark room. Surveys were performed of the overpack and camera by the driver after the wreck. The driver and MS Highway State Patrol Officer waited with the overpack and camera until DRH and the Licensee's ARSO arrived on site to take possession of the camera. MS Report Number: MS 120004
Licensee's leak test reported to DRH was less than 0.005 microCuries. Notified R4DO (Powers) and FSME Events Resources via email. | ||
| ENS 48243 | 24 August 2012 05:00:00 | Agreement State | Mississippi Agreement State Report - Radiography Camera Stuck Source | The following information was obtained from the state of Mississippi via email: DRH (Mississippi Department of Radiation Health) was notified on 8/27/2012 by Licensee's RSO regarding a stuck source incident that occurred on 8/24/2012 while performing industrial radiography at a temporary job site in Mississippi. The RSO claims the camera (880D) fell onto the guide tube during one of the shots and crimped the guide tube preventing the source from retracting back into the camera. The RSO suspects the technician may have pulled on the cranks while trying to crank back in the source after the shot. This could have then caused the camera to fall onto the guide tube and crimp it. The restricted area boundary was readjusted to one (1) mR/hr, maintained, and the RSO was called by the radiographers at the job site. An ARSO and technician from the company who are trained in source retrieval arrived at the job site and retrieved the source. The camera was wiped and leak tests were submitted for analysis. The Licensee's ARSO received 82 mR and the technician received 8 mR/hr from actions taken during the source retrieval. MS Report Number: MS 120003
The following update was received from the State of Mississippi via email: Test for leakage and/or contamination received from the Licensee was less than .005 microCuries. Notified R4DO (Lantz) and FSME via email. |
