The following was received from the State of
New York via fax:
On 3/18/2014 NYC sanitation workers clearing a vacant lot in Queens discovered one depleted uranium (DU) shield and the remains of 3 to 4 plastic outer-packs from Mallinckrodt manufactured Mo/Tc radiopharmaceutical generators. Information on the packaging indicates the generators were supplied to NYS Licensee C5413 Triad Isotopes in 2013. Discussions with Triad Isotopes on 3/19/2014 indicate that Mallinckrodt contacted them in October 2013 regarding a shipment of 5 spent generators being returned from Triad to Mallinckrodt via their contractor MDS [that] did not make it to Mallinckrodt in Missouri. The DU shield is being secured by NYC while waiting to be picked up by Triad. NRC Region 3 has been contacted. NYS Incident #1055
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.
