[Metro Metals] phoned that a flatbed truck with metal scrap from a recycler in WA (Paymore Recycling & Salvage, Montesano, WA) set off their
portal monitor. Hand-held exposure meters were used to survey the load and levels were found at 4000 microrem/hr. This load is waiting for
RPS [Radiation Protection Services] to check.
Responded to Metro Metals. Found a static bar. Wrapped and sent back to recycler. Max reading, with Ludlum 2401 EC, at front edge of bar was 6 mR/hr. Exploranium identified Am-241. Static bar was about 5 to 6 feet in length and was cut in half. Item was wrapped in plastic and placed in a drum for return to the recycler.

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.
