gauges containing
Cd-109.
The licensee has notified R3 (Kulzer).
The missing gauges' function was to check for lead in paint. The 13 missing sources were in Niton model 309 detectors with an aggregate activity of 247 mCi of Cd-109. Four of the sources contained 50 mCi and the remaining nine contained a total of 47 mCi.
The sources were last known to be in the Herman Kiefer Health Complex, 1151 Taylor Street, Detroit, MI.
Notified the R3DO (Hills), ILTAB (Whitney), FSME Event Resources, and Canada.
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.
