Etats-unis : Bridgeport : vol d’une jauge de mesure d’humidité




26 juillet 2016


Le 26 juillet à 4 h, après fracture du coffre et retrait de son étui, une jauge a été volée dans la voiture d’un technicien. Cette jauge est de modèle Troxler et elle contient 8 mCi Césium-137, 40 mCi américium-241 et du Beryllium. Le propriétaire a informé la police locale qui a lancé une enquête. A 16 h 37, le Connecticut Department of Energy and Environmental Protection, Radiation Division (CDEEPRD) a reçu un appel de la police de l’État du Connecticut les informant que la jauge d’humidité avait été localisée et récupéré intacte mais en dehors de son boitier. A 18 h 13 le 26/07/2016 le CDEEPRD a été informé, toujours par téléphone, qu’un individu a tenté de mettre en gage la jauge d’humidité dans un magasin de Bridgeport. Le personnel du magasin a immédiatement informé le Service de police de Bridgeport et les agents ont arrêté l’individu. La jauge a été restituée à son propriétaire qui l’a remise dans une autre boîte de stockage qu’il possédait.

Pour les autorités ce type de source de catégorie 3 est peu susceptibles de causer des dommages permanents à des personnes car elles contiennent une très petite quantité de matière radioactive qui ne causerait aucun dommage permanent.

STOLEN MOISTURE-DENSITY GAUGE

A moisture-density gauge (Troxler - Model 3440, Serial Number 34924) was stolen from a technician’s vehicle. The vehicle trunk was broken into, the lockdown chains were cut, and the entire gauge was removed. This model Troxler typically contains 8 mCi Cesium-137 and 40 mCi Americium-241:Beryllium.

The licensee has notified local law enforcement and an investigation continues.

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.
