| ENS 54745 | 12 June 2020 07:00:00 | Agreement State | Agreement State Report - Medical Event | The following was received from the Arizona Department of Health Services (the Department) via email: On June 12, 2020, the Department received notification from the licensee of a possible medical event involving an I-125 eye plaque. A patient was implanted with an eye plaque on June 4, with a prescribed dose of 85 Gy. On June 8, the patient had a stroke and was admitted to St. Joseph's Medical Center. Once the patient was able to be transported, they were transported back to the Mayo Clinic Hospital on June 9. It was then determined that the patient was not strong enough to endure the procedure for removing the eye plaque. The eye plaque was finally removed on June 11 and the final dose to the tumor was 123.5 Gy or 145.3 percent of the prescription. The Department has requested additional information and continues to investigate the event. Arizona Incident 20-010 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. | ||

| ENS 54673 | 18 April 2020 01:00:00 | Agreement State | Agreement State Report - Possible Medical Event | The following was received from the state of Arizona via email: On April 17, 2020, at approximately 1800 (MDT), the Department (Arizona Department of Health Services) received notification from the licensee of a possible medical event involving Yttrium-90 radiolabeled glass microspheres (Therasphere). The dose on the written directive was 150 Gy and the pre-treatment measurement was approximately 4.6 GBq. Following the delivery, the nuclear medicine technologist took readings of the waste containers and got an average of 4.58 mR/hr (highest of 11.8 mR/hr) from the first jar and an average of 1.39 mR/hr (highest of 2.6 mR/hr) from the second jar. The licensee is investigating the irregular waste readings and attempting to calculate the actual dose to the patient. The Department has requested additional information and continues to investigate the event. Arizona Event No. 20-009 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. | ||
| ENS 54522 | 11 February 2020 07:00:00 | Agreement State | Agreement State Report - Lost Brachytherapy Seed | The following was received from the state of Arizona via email: The Department (Arizona Department of Health Services) has received notification from the licensee (Scottsdale Healthcare dba Honorhealth Scottsdale Shea Medical Center) that one brachytherapy seed has been lost. It is assumed that the seed went down the drain of an autopsy table on 02/11/2020. All other seeds are accounted for and stored in the licensee's brachytherapy hot lab. The seed model is Civadot, and the isotope is Palladium-103. The Lot ID from which the seed originated is CSH-201. The calibrated activity of the seed on 12/10/2019 was 0.783 mCi (29.0 MBq). The calculated activity as of 02/12/2020 is 0.058 mCi (2.15 MBq). The Department has requested additional information and continues to investigate the event. Arizona Incident Number: 20-003 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.

| ENS 54412 | 26 November 2019 07:00:00 | Agreement State | Agreement State Report - Possible Found Radioactive Material | The following information was received via phone call: A member of the public earlier today identified a container on National Forest Service land near Globe, Arizona that is labeled as having radioactive material. Pictures of the container show "B of E permit 681, Serial Number D-8011, Radiation, Return to Dow Chemical Company, Rocky Flats." This is an initial report. Arizona Department of Health Services personnel will investigate presently and provide an update.
The following update was received from the Arizona Department of Health Services via email: The container turned out to be a metal lid based on the orientation of the data plaques and the safety top. We (Arizona Department of Health Services) performed exposure and contamination surveys onsite and everything came back at background. Notified the R4DO (Pick) and NMSS via email. |
