Event Report ID No.: LA20200002
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
