The following synopsis of information was provided by the
Massachusetts Radiation Control Program (the Agency) via email:
At 1900 EDT on April 17, 2023, Lantheus Medical Imaging, Inc. (the Licensee) reported that at 1500 EDT on that day it had discovered a package containing a 15 Curie Mo-99/Tc-99m generator was not delivered to RLS in Van Nuys, CA (the intended recipient).
On April 18 at 1200 EDT, the Licensee learned that the package was still in the delivery truck in California. The driver had two deliveries to make on April 17, 2023, but only made one of the deliveries, leaving the package containing the generator in his vehicle overnight. Once the package was found, it was delivered to its intended recipient.
The reporting requirement is immediate per 105 CMR 120.281(A)(1), missing licensed radioactive materials in aggregate quantity equal to or greater than 1,000 times quantity specified in 105 CMR 120.297, Appendix C.
MA Number.: TBD
The Agency considers this event to be open.
THIS MATERIAL EVENT CONTAINS A 'Category 3' LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial
gauges involving high activity sources (for example: level
gauges, dredger
gauges, conveyor
gauges and spinning pipe
gauges) and well logging. For additional information go to
