| AGREEMENT STATE REPORT - I-125 APPLICATOR LEAK TEST FAILURE The following was received via e-mail: During a Wisconsin Department of Health Services inspection a previously unreported event was discovered. The date of the event is still being determined. "While performing a manual brachytherapy procedure, the Mick applicator became jammed and the licensee switched to a different applicator to finish the procedure. Following the procedure, the [Radiation Safety Officer] RSO wiped the jammed device and found contamination so several I-125 seeds were isolated and held for decay in storage." This indicates that the device failed a leak test, which is a reportable event. * * * UPDATE ON 05/10/2019 AT 1108 EDT FROM JOSEPH ROSS TO JEFFERY HERRERA * * * "On December 6, 2016, while performing a manual brachytherapy procedure, a Mick applicator became jammed when the oncologist was attempting to insert a seed. The radiation oncologist removed the Mick applicator and switched to an extra Mick applicator with a different cartridge of seeds. A surgeon continued implanting seeds with the physicist to finish the procedure. Meanwhile, the radiation oncologist forcefully extracted the cartridge from the jammed Mick applicator. This was when the physicist/RSO believed that a seed was ruptured. Following the procedure, the RSO took the Mick applicator to the nuclear medicine hot lab and wiped the device and cartridge. The RSO found contamination on the seeds/cartridge so thirteen I-125 seeds (.333mCi each) were isolated and held for decay in storage in the hot lab. "There is no indication of contamination in the operating room surveys or any expected uptake by the patient." Notified R3DO (Stoedter) and NMSS Events (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. |

| UNPLANNED CONTAMINATION EVENT DUE TO BREACHED CS-137 SOURCE The Radiation Safety Officer (RSO) at International Isotopes, Inc. reported that at 2130 PDT on 5/2/19, while changing out the Cs-137 source on a research irradiator, they breached the source which resulted in widespread contamination and a possible uptake event. The irradiator is a JL Shepard Mark 168A and is located at the Harborview Research and Training Facility at the University of Washington in Seattle, WA. International Isotopes, Inc. is an NRC licensee working under reciprocity in the State of Washington (an agreement state). After discovery of the breach, the immediate area was isolated, the building was ordered evacuated, and the ventilation was secured. Indications are that the seven members of the source retrieval team were externally and potentially internally contaminated. The State of Washington was notified. The University of Washington RSO was sending response teams to the area. A local hazardous material team is on site. The source was reported to be 2800 Ci. Notified DHS SWO, DOE Ops Center, FEMA Ops Center, HHS Ops Center, DHS NICC, USDA Ops Center, EPA Emergency Ops Center, FDA Emergency Ops Center (email), FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email). * * * UPDATE ON 05/03/2019 AT 1545 EDT FROM TRISTAN HAY TO JEFFREY WHITED * * * The following update was received via E-mail from the Washington State Department of Health: "University of Washington (UW) was having their research irradiator (Mark-1 SERIES / Cs-137) disposed of by International Isotopes (NRC License 11-27680-01MD). The Agreement state regulators were present to verify dose measurements and observe ALARA practices. During the source removal and transfer into the transport shielded cask, there was a breach of the sealed source and a small portion of the source was released into the working area. The working area was comprised of the irradiator unit, the shielded containment rig, the loading dock, a 100 feet radius around the loading dock, and the Harborview Research and Technology Center floors 1-3 and stair well. The source was encapsulated with International Isotopes' source housing capsule. A breach was identified during the precursor wipe survey performed prior to putting it into the source housing unit. Once contamination was identified, all personnel performed area contamination surveys and secured and taped off the work space area. All personnel who were present at some point during the transfer were notified of the potential contamination and were given special instructions to return to the Harborview Medical Center area for decontamination. "Simultaneously the NRC, Washington Radiation Emergency Hotline, and the [National Materials Event Database] NMED were notified of the situation by International Isotopes immediately after the incident occurred. Seattle Fire and Seattle Hazmat units were dispatched to the scene to assess the situation and begin decontamination protocols. The International Isotope workers, UW RSO, FBI agent, and other present workers were decontaminated and placed in a contained area of the Harborview Medical Center Emergency Room. Bioassay samples were collected from urine and blood from the contaminated individuals." Additionally, employees from the State of Washington who responded to the event were surveyed, with the highest level of contamination being 300 cpm on the individual's shoes. Washington State Licensee: University of Washington Washington Agreement State License No. C001 Event Report ID No.: WA-19-015 Notified R4DO (Werner), IRD MOC (Gott), NMSS (Rivera-Capella), and NMSS Events Notification via e-mail, DHS SWO, DOE Ops Center, FEMA Ops Center, HHS Ops Center, DHS NICC, USDA Ops Center, EPA Emergency Ops Center, FDA Emergency Ops Center (email), FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email). * * * UPDATE ON 05/04/2019 AT 2136 EDT FROM JOHN MILLER TO JEFFREY WHITED * * * The following update is a synopsis of information received via E-mail from International Isotopes: In its E-mail, the licensee provided an initial incident report regarding the breached Cs-137 source incident that occurred during the removal of the source from the Research Irradiator at the Harborview Training and Research Building. The licensee provided a summary of planned work, a summary of the incident, a summary of the whole-body exposures received by International Isotopes and contractor employees, a summary of initial personnel skin contamination results, a summary of post-decontamination personnel skin contamination results, and a summary of recovery actions taken to date. According to its assessment, the licensee indicated that the highest whole-body exposure to any one individual was 55 mrem. The majority of surveys taken at the loading dock level indicated that surfaces were contaminated in the 50,000 - 300,000 cpm range. The summary of recovery actions taken to date are as follows: International Isotopes hired a contractor to perform decontamination and remediation of the affected areas. The Department of Energy, Region 8, Radiological Assistance Program team surveyed the building floors. International Isotopes employees surveyed the parking lot area where emergency response operations took place reducing the size of the controlled area, marking spots with identified levels. The loading dock area was further isolated from the building by covering outdoor louvers and double door between corridor and loading dock with heavy plastic. International Isotopes remains on-site to support the contractor and the University of Washington by performing assessment surveys and development of the decontamination and recovery plan.
