The following was received from the
Utah Division of Radiation Control (the Division) via email:
A portable gauge user failed to adequately secure the transportation case containing a Troxler 3430 gauge when leaving the jobsite. The user noticed the gauge was missing after travelling some distance from the jobsite. The user retraced his path back to the jobsite, but was unable to locate the gauge. The licensee then contacted the Division [at 1422 MDT] to report that the gauge was missing. During a subsequent telephone call [at 1503 MDT], the licensee informed the Division that the gauge had been located during an additional search by the user. The gauge was found just outside the jobsite entrance. The Troxler gauge contains a 40 mCi Am-241/Be sealed source and an 8 mCi Cs-137 sealed source.
Utah Event Number: UT 200006
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.
