The following information was provided by the
Minnesota Department of Health (
MDH) via email:
The Minnesota Department of Health was notified on 9/27/2022 of a lost localization seed (I-125, 0.188 mCi) that went missing on 6/30/2022. The seed was not identified as missing until 9/22/2022 during an audit. The specimen, with the seed, was transported to pathology and kept with the tissue during the processing of the sample. The pathologist believed the seed was non-radioactive due to the proper paperwork not being present with the seed (the licensee uses radioactive and magnetic seeds). The tissue specimen and seed were disposed of in the biohazard waste stream.
Minnesota Event Number: MN220006
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.
