The following report is a synopsis of an email received from the
Florida Bureau of Radiation Control (
BRC):
On September 6, 2019, Westrock CP, LLC called to notify the BRC of a lost Cs-137 source (serial number: S99J2804). The activity of the source as measured on approximately January 1, 1997, was 5 mCi. Westrock had planned to remove five sources during a semi-annual inventory survey, but they were unable to locate one of the sources. A more sensitive survey meter was then flown to the licensee, but it was unable to detect any activity in the area where the source was expected to be.
Florida Incident Number: FL19-111
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.
