The following information was provided by the
Colorado Department of Public Health and Environment via email:
A customer shipped a package containing an AirSentry II-IMS unit with a 10 mCi nickel-63 source to Particle Measuring Systems. On February 16, 2023, the customer emailed that the package should have arrived. Particle Measuring Systems contacted the common carrier, whose tracking system showed the package was delivered on February 7, 2023. The site conducted an extensive search but could not locate the package. The Radiation Safety Officer was informed on March 1, 2023, that the package was lost. The Colorado Radioactive Materials Unit was subsequently notified of this event on March 10, 2023.
Colorado Event Number: CO 230009
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.
