The following is a summary of information received from the
Georgia Radioactive Material Program (the Department) via email:
On January 6, 2024, the Department was notified by the licensee, that on January 3, 2024, a nuclear medicine technologist was performing routine leak testing of sealed sources in preparation of returning the sources to the manufacturer. The leak test indicated one of the sealed sources (Co-57, 21.12 microcuries as of 2/1/2023, manufacturer: Eckert and Ziegler, model: PHI-0124, serial number: V6-599) had more than 0.005 microcuries of removable Co-57 contamination. The sealed source was secured, the radiation safety officer (RSO) was notified, and decontamination protocol was followed.
Post-decontamination surveys and wipe tests of the staff and department indicated that there was no detectable contamination in the department or on staff members. The sealed source and the waste generated during the decontamination process were placed in leakproof containers and marked as containing Co-57. All items are currently stored in the nuclear medicine hot lab. Disposal with a waste disposal company has been arranged.
Georgia NMED event number: 76
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.
