| Title | NON-AGREEMENT State Report - Lost Medical Dose |
| Event Description | The following information was provided by the licensee via telephone:
On February 1, 2023, a clinical dose of radium (Ra-223) dichloride (146 microcuries) was delivered by courier to the hospital hot lab. At approximately 1400 CST on February 2, 2023, a technician identified that the dose was missing while attempting to retrieve it in preparation to administer it to a patient. The licensee performed a search for the missing dose and suspects that the package with the dose was thrown away during cleanup of the hot lab on the afternoon of February 1, 2023. The licensee stated that they did not believe that an exposure to a member of the public would result from the dose because Ra-223 is an alpha emitter with a very low gamma yield. In addition, the radioisotope was enclosed in a syringe and external packaging. The Radiation Safety Officer is still investigating the events of the lost medical isotope. 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.
