The following was received from the State of
Louisiana, Department of Environmental Quality:
On January 05, 2021, [the Radiation Safety Officer] (RSO) dropped off seventeen sources to the common carrier for shipment to various locations. Alpha-Omega contacted the Louisiana Department of Environmental Quality / Emergency Response Services Division / Radiation Section [at 1530 CST on 1/15/21] to report that a High Dose Rate (HDR) Ir-192 source was lost in transit with the common carrier. The source was being shipped to Mid-Columbia Medical Center, The Dalles, OR. The source serial number is D36R0392. The activity of the Ir-192 source on 1/5/21 was 10.568 Ci (391.016 GBq) when it was shipped. The current activity on 1/15/21 is 9.626 Ci (356.162 GBq). The common carrier does not show this source being tracked or received.
LA Event Report ID No.: LA 20210001
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.

Note: This device is assigned an
IAEA Category 3 value based on the actual radioactivity of the source, not on the device type. (Reference
IAEA RG-G-1.9)
