The device has been located by the shipment carrier and is scheduled to be returned to the licensee. Notified R4DO (Proulx), NMSS (Rivera-Capella), IR MOC (Grant), ILTAB (Clark), and NMSS Events Notification (email). THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

EN Revision Imported Date : 7/22/2020 AGREEMENT STATE REPORT - SUSPECTED DOSE TO WRONG ORGAN The following is a summary of email received from the Oklahoma Department of Environmental Quality (OK DEQ): OK DEQ was just informed that yesterday, June 23, 2020, a medical event may have occurred involving a patient undergoing radiation therapy to the vagina. The treatment plan called for three (3) fractions delivered by a High Dose Rate (HDR) afterloader. After the first fraction was administered, the therapist noted the presence of fecal matter on the applicator. The licensee is assuming that the applicator was placed in the patient's rectum instead of the vagina. The treatment plan estimated a dose of 0.85 Sv to the rectum due to the procedure. The licensee estimates the actual dose delivered, assuming the applicator was in the rectum, to be 1.5 Sv. The licensee is the University of Oklahoma Health Science Center, OK-03176-01. This is a Type A medical broadscope license. OK DEQ will provide more information as it becomes available.

The following update was received from the OK DEQ via email: OK DEQ is correcting the licensee name and license number. Initially, they were reported as the University of Oklahoma Health Science Center, OK-03176-01. The correct licensee is OU Medicine, Inc., License No. OK-21035-01. Notified R4DO (Drake) and NMSS Event Notification via email. A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

The following information was obtained from the State of Oklahoma via email: On August 27, 2018 (Oklahoma Department of Environmental Quality (DEQ)) were informed of an incident which occurred approximately 2140 CDT on August 24, 2018 involving 3 radiographers working for IRISNDT (OK-30246-02). The crew was working at a fabrication shop in Port of Catoosa, OK using a 95 curie Ir-192 source. The crew consisted of one certified radiographer, one radiographer trainer, and one assistant radiographer. The radiographer approached the collimator and knelt down over the guide tube. The assistant and the instructor unlocked the camera and walked back to the crank. Looking back at the camera, they did not see the radiographer and assumed he had already left the area. They began to crank out the source when the radiographer yelled and ran from the area. A re-enactment of the event using a pocket dosimeter recorded a dose of 62.1 mR, the direct reading dosimeter worn by the radiographer recorded a dose of 6 mR, probably due to shielding by the radiographers body. The whole-body badge reported a dose of 211 mR for the current month. A review of the daily exposure records for this monitoring period showed that the individual should have received approximately 155 mR previously, so the dose recorded for this incident is approximately 56 mR. Immediately after the incident the radiographer began complaining of a burning sensation and inflammation of his right shin area. (Oklahoma DEQ) are arranging with a local hospital to have him seen by a radiation oncologist. (Oklahoma DEQ) will conduct a reactive inspection of the licensee.

The following was received via email from the State of Oklahoma via email: After the reactive inspection yesterday, (Oklahoma Department of Environmental Quality) has determined that the injury reported by the radiographer was due to his hitting his shin on a stand as he ran from the area. It does not appear that this incident resulted in an over-exposure to anyone. Notified R4DO (Hay) and Doug Ballock and NMSS Events Notification via email.

The State of Oklahoma reported that contamination from a leaking Ba-137 generator was discovered in a 'shed' at the University of Tulsa. It is estimated that approximately 1 milliCurie of Cs-137, used in the generator, was leaked. The licensee, Tracerco, licensed by the State of Texas, was using the generator for tracer studies on University of Tulsa equipment under a reciprocity agreement with the State of Oklahoma. The contamination occurred between October and November of 2014. Tracerco discovered the generator leakage at their Texas facility in May, 2015 but only recently informed the University of Tulsa. The Radiation Safety Officer at the University of Tulsa surveyed the area on 8/25/15 and obtained count rates as high as 100,000 cpm inside the shed. Contamination was also found outside of the shed's location. According to Tracerco, it is estimated that approximately 1 milliCurie of Cs-137 was leaked at the University of Tulsa. The University of Tulsa reported that approximately eight individuals work in the area at least some of the time, however, the University is working on obtaining occupancy information at the contaminated location. The shed has been quarantined. The Ba-137 generator, which contained 50 milliCuries of Cs-137, was manufactured by the China Institute of Atomic Energy. The State of Oklahoma will be investigating the event and will be determining the amount of exposure to the individuals. Tracerco is continuing evaluating the event. The State of Texas reported the leaking generator under NRC EN #51102

The following information was received via facsimile: On August 27, 2015 the Oklahoma Environmental Agency Radiation Management Section performed a reactive inspection of this facility. The facility consists of a closed flow-loop pipeline which water or petroleum was pumped through. A port was used to inject radioactive tracers into the material to study its behavior in the flow-loop. Normally the crew from Tracerco would set up the generator at the injection port which was located on a platform about 12 feet above grade. However for some reason, possibly bad weather, the crew that performed the work last year decided to set up in an enclosed pump house immediately adjacent to the pipeline. At some point during the procedure an estimated 0.1 mCi of Cs-137 (not 1 mCi as previously reported) was released in the interior of the structure. The material was in the form of small resin spheres, about the size of a poppy seed, with the Cesium coating the surface. Sometime around May of this year, after Tracerco discovered that the generator was leaking and their own facility was contaminated, they sent staff back to the University to survey for contamination. However, they were unaware that the previous crew had used the pump house, and only surveyed around the injection port where they found no contamination. No further action was taken until August 24 when Tracerco employees again visited the site and surveyed the pump house. After finding the contamination they decontaminated the area using adhesive tape to pick up the material. Two office chairs and a floor mat were also found to be contaminated and removed to an area the university uses for radioactive storage. None of the University employees who worked at the facility were badged. During our inspection we noted that the background radiation level was elevated in the vicinity of the pump house and flow-loop (approx. 100 microR/hr as measured with a Victoreen 450P, this was about 10 X background off the facility). It should be noted the University has it's own license and uses or stores about 25 fixed gauges, with a total possession limit of 15 Ci., either on or near the flow-loop. Surveys inside the pump house showed isolated areas of contamination with radiation levels as high as 500 micro-R/hr. Multiple areas (usually concrete joints or gravel at the edge of the concrete) around the exterior of the pump house were also found to be contaminated with dose rates around 200 microR/hr. One trailer adjacent to the pump house was found to have a small spot of contamination in the carpet just inside the door. This was surveyed at 260 micro-R/hr. This trailer was used for office space for two persons, one of whom is a member of the public. 14 samples were collected at various points and will be counted next week. The University has restricted access to the contaminated areas but has continued to allow essential radiation workers to enter when necessary to operate the flow-loop. They were instructed to require anyone entering to wear disposable gloves and shoe covers. Tracerco has arranged for Chase Environmental to characterize and remediate the facility. This will begin on August 31 and is expected to take 5 to 7 days. Tracerco has also arranged for any university staff who desire to be scanned at a full-body counter in Houston. Notified R4DO (Campbell) and via E-mail the NMSS Events Notification group.

The following was received from the State of Oklahoma via email: Building and Earth Sciences has reported that a Troxler Model 3430 (S/N 36097) was stolen from a location in Ponca City, OK. The case was in the back of a truck and some time during the night it was opened and the gauge removed. The RSO is on the way to the site now, (the Oklahoma Department of Environmental Quality) will provide more information as it becomes available. Troxler Model 3420 Density gauges typically contain Cs-137 8 mCi and Am-241/Be 40 mCi sources.

• * * UPDATE FROM MIKE BRODERICK TO JOHN SHOEMAKER AT 1100 EDT ON 6/9/2013 * * *

The State of Oklahoma reports that the gauge has been recovered and is now in the possession of the licensee. A private citizen found the missing gauge on the side of a road near the location where the gauge was stolen in Ponca City, OK. The source rod was still locked and it is believed that no exposures have occurred. The licensee will return the gauge to a secure storage location. Notified R4DO (Spitzberg) and FSME Events Resource and ILTAB via email. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

The State representative reported that scrap metal received by a metal processor in Sand Springs, OK, set off the facility's gate radiation monitor. Investigation into the alarm determined that the radiation was coming from a foil source of unknown origin. The source dimensions are 3 inches by 1/2 inch with a contact reading (using a Ludlum Model 3) of 200 mR/hr. The scrap metal processor notified the State which dispatched inspectors to the site. The State found that the source also had loose surface contamination. Investigation has determined that four individuals had handled the source. The State was able to contact one of those individuals and a survey of the individual revealed no indication of contamination. The State has not yet been able to contact the other three people involve in handling the source. The source has been wrapped in lead shielding material and secured in a safe location. The State plans to perform a Gamma Spec analysis of the source to determine the isotope. The investigation into the origin of the source has been unproductive so far. It appears that the scrap metal came from a intermediary scrap metal dealer.

• * * UPDATE ON 10/5/05 @ 15:20 FROM SAMPSON TO ABRAMOVITZ * * *

The source (foil) was determined to be Radium-226. The Curie content was not determined but was estimated to be in the micro Curie range. The loose contamination was not found on any other surfaces, only on the test swipe. The four individuals who contacted this source were contacted and an estimate of their dose is in progress.
