A generally licensed NRD model P-2021-3000 … A generally licensed NRD model P-2021-3000 air ionizer (s/n A2DV726) was discovered missing following the demolition of a wall. During the installation of a new cleaning bench on July 22 and 23, a wall was demolished. The nitrogen line and the attached blow-off gun containing the device was attached to that wall and the assumption is the ionizer was in the demolition debris. The debris was moved to a Waste Management dumpster for a short time and then sent to a landfill in Blaine, MN. The landfill was searched, but the device was not found. These devices generally have an initial activity of 10 mCi of Po-210, but the caller did not know the activity of the lost device. </br>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.re close to it for a period of many weeks. +
