The following information was received from the
Massachusetts Radiation Control Program (the Agency) via email:
The licensee (QSA Global, Inc., License No. 12-8361) reported at 1015 [EDT] today (July 11, 2023), that it discovered yesterday (July 10, 2023) at 1553 that one of two packages destined for delivery to AMCOL Ingenieria LTDA of Bogota, Columbia was missing. Each of the two packages was a single QSA Global, Inc. model 650L source changer containing an iridium-192 sealed source(s) shipped on June 26, 2023. One of the two packages was received by AMCOL Ingenieria LTDA of Bogota, Columbia on July 10, 2023.
The missing package was a QSA Global, Inc. Model 650L source changer, serial number 120 containing two sealed sources of iridium-192, 104.2 curies (3.86 TBq) and 104.3 curies (3.86 TBq), respectively. The licensee reported that the missing package was last known to be at the carrier's sorting facility in Memphis, TN, on July 1, 2023. The carrier package tracking number was provided by the licensee.
The licensee then reported at approximately 1300 on July 11, 2023, that the missing package was found by the carrier at the carrier's Memphis, TN facility, and that the package will likely be moved forward by the carrier to the Bogota, Columbia destination.
The reporting requirement is immediate and is of 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 and of 105 CMR 120.077(B).
The Agency considers this event to be open.
THIS MATERIAL EVENT CONTAINS A 'Category 2' LEVEL OF RADIOACTIVE MATERIAL
Category 2 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 a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate
brachytherapy and medium dose rate
brachytherapy. For additional information go to
