| ENS 50761 | 24 January 2015 06:00:00 | Agreement State | Agreement State Report - Attempted Theft of Radiographic Equipment | The following information was obtained from the State of Kansas via email: The Team Industrial office in Wichita was broken into. They have video evidence of attempt to access the licensed material of concern. All material is accounted for. Missing items include UT equipment, computers, vehicle keys (vehicles were not taken), files were ransacked including the sensitive information files. Unknown at this time if sensitive information was taken. Police notified. Kansas Case Number: KS150001
The following updated information was provided by the Kansas Department of Health and Environment via email: The Kansas Department of Health and Environment provided additional detail regarding the event and the items stolen. Radioactive material was not stolen as a result of the break in attempt(s). Local law enforcement and FBI were notified and investigated the event. Additional corrective actions were taken by the licensee to secure sensitive materials and equipment. A reward has not been offered for return of the stolen items. A detailed list of the missing items has been provided to the Wichita police department. Notified R4DO (Vasquez), ILTAB (Wray) and NMSS Events Notification (email). | ||
| ENS 48167 | 6 August 2012 19:00:00 | 10 CFR 30.50(b)(2) | Radiography Camera Source Failed to Retract Due to Damaged Guide Tube | A radiography crew working at the Marathon Refinery in Detroit, MI experienced a failure of the source to retract on their QSA-880-D radiography camera due to the source binding in the guide tube. While the source was out, the radiography camera fell approximately 18 inches from the scaffolding and landed on the guide tube end. The personnel cordoned off the area and called for assistance. The site supervisor was able to fully retract the source into the shielded position. The radiography camera was removed from service and is being sent to the manufacturer for evaluation. Based on dosimetry readings, exposure levels were not above normal readings. The highest badge reading resulted in 54 mrem. | ||
| ENS 46886 | 24 May 2011 18:20:00 | Agreement State | Agreement State Report - Stuck Radiography Camera Source | The following information was received via email: While using a QSA Global 880D radiographic exposure device, the licensee's crew was unable to move the drive cable forward or backward. It appeared that the source was moved slightly out of the fully shielded position when the device was unlocked prior to the attempt to crank out the source. The crew was unable to retract the source and lock the device. A licensee employee trained in source retrieval was sent to the site. The employee disassembled a portion of the drive cable which gave him access to manually pull the drive cable in the direction that would retract the source. The cable was moved approximately 1/4 inch. This placed the source in the fully shielded position and the source was locked in the shielded position. Only licensee personnel were potentially exposed to radiation from the device during the incident. Licensee personnel stated that they did not step in front of the camera at any point during the incident. The radiographer used the survey meter to determine where to stand to receive the least exposure while checking the camera. At one point he reached forward with the survey meter and measured 200 mR/hr at the front port of the device. Dose estimates for licensee personnel associated in the incident were well below the limits for occupationally exposed individuals. Utah Event Report ID Number: UT - 110004 | ||
| ENS 44052 | 10 March 2008 05:00:00 | Agreement State | Nebraska Agreement State Report - Potential Overexposure | The State of Nebraska Department of Health & Human Services, Radiation Control Program, Radioactive Materials Branch reported that a radiographer employed by Team Industrial Services, Inc. was potentially overexposed while performing radiography at a Nebraska City, NE facility. Team Industrial Services, Inc. is performing work in Nebraska under reciprocity of their Illinois license. On March 7, 2008, while at the job site, the radiographer noticed that his direct-reading pocket dosimeter was off-scale. He reported this to the regional Team Industrial Services RSO and stated that he believed he just bumped the dosimeter to cause the off-scale condition. The RSO directed him to send his TLD to Landauer Laboratories for processing. On March 10, 2008, Landauer informed the RSO that the TLD indicated that the radiographer received 7.753 REM Deep Dose Equivalent. The Team Industrial RSO notified his corporate RSO, who then notified the State of Nebraska. The radiographer has been restricted from radiation areas while Team Industrial and the State of Nebraska investigates this incident.
On March 11, 2008, the Corporate RSO for Team Industrial Services, Inc. called to report that one of their industrial radiographers had received an exposure of 7.753 rems to their dosimetry badge while conducting radiographic operations, under reciprocity, at a construction site in Nebraska City, NE. The dates that the radiographer had performed radiography were the evening of March 4, 2008 and the early morning of March 5, 2008. At the time the radiographer noted that his pencil dosimeter had gone off-scale. He did not notify the FRSO in the licensee's Illinois office until March 7, 2008 at which time his dosimetry badge was sent off to Landauer for emergency processing. Landauer verbally reported the findings to Team Industrial on March 10, 2008. During the subsequent investigation of the incident, the radiographer admitted that he had performed radiography alone at the temporary jobsite alone. Four possible scenarios were developed during the investigation. First, he had received the exposure because the confined space in which the exposures were made caused the radiographer and assistant to be in a 200-300 Mr/hr field. This was discounted because the assistant only had 30 mrem on her pencil dosimeter and badge readings were 137 mrem for February and 4 mrem for March (both sent in for emergency processing). The second scenario involved the statement by the radiographer that he had dropped his dosimetry badge near the camera and guide tube and that he may have "bumped" his pencil dosimeter. Calculations could not substantiate the exposure to the badge. In addition, it was too coincidental that both the dropped badge and "bumped" pencil dosimeter happened at the same time. The third scenario was that this was an intentional exposure of the badge. Intensive questioning by the State of Nebraska inspectors and Team management could not substantiate this scenario. The last and most probable scenario was that the radiographer did not fully retract the source following a radiography shot and failed to properly conduct a complete survey around the camera and guide tube before repositioning the guide tube for the next radiography shot. There is no evidence to discount any of the above scenarios so the investigation is considered to be inconclusive. A complete investigation report is in process. Violations have been identified and will be included in the final report with the response from the licensee. Notified R4DO(Deese) and FSME(Kock) |
