The following information was provided by the
Massachusetts Radioactive Material Unit (the Agency) via email:
On 4/30/25, four radioactive material packages were to be received by the licensee, Boston University and Boston Medical Center (MA license number 44-0062). Two packages showed up just after 1000 EDT, but one package containing 7mCi of S-35 and another package containing 0.5 mCi of P-32 were not received. The packages were shipped from Revvity Health Sciences, Inc. (MA license number 00-3200).
An investigation was opened with the common carrier, which is currently ongoing.
The reporting requirement is within 30 days and is of 105 CMR [Code of Massachusetts Regulations] 120.281(A)(2), missing licensed radioactive materials in aggregate quantity equal to or greater than 10 times quantity specified in 105 CMR 120.297, Appendix C.
The Agency considers this event to be open.
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.
