| Event Description | 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. 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. |
