The following information was received from the State of
Oklahoma via email:
Goodyear Tire and Rubber Co. has reported the loss of a 3M Model 703 Static Meter (S/N 411617). This device was possessed under Oklahoma GLD [generally licensed device] registration GLD0013. It was manufactured in 1977 and initially contained 250 mCi of tritium, which would have decayed to approximately 20 mCi today. Goodyear obtained the device in 2002 and used it for 2 or 3 years before placing it into storage. It was discovered missing earlier this month.
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.
