Montreal, Quebec — On the evening of July 15, 2020, a vehicle containing a Troxler portable gauge was stolen in Montreal. A police report has been filed with the local police force. This radiation device contains the nuclear substance Cs-137 with an activity of 158 MBq.
The radiation device is categorized as Category 4, based on internationally established standards as described in IAEA Safety Standards Series No. RS-G-1.9, Categorization of Radioactive Sources, 2005.
This means that this radioactive material is currently classified as “low risk” and is unlikely to be dangerous, says Canadian Association of Recycling Industries (CNSC).
However, it must still be safely and securely controlled. It is very unlikely that anyone would be permanently injured by this amount of radioactive material, but this amount of unshielded radioactive material, if not safely managed or securely protected, could temporarily injure someone who handled it or was otherwise in contact with it, or who was close to it for a period of several weeks. However, such injury is unlikely.
