The portable geotechnical gauge, which is used to measure the density of asphalt, soil, aggregate or concrete, could pose a health risk to the public due to the elements it contains.
The device, a Troxler 3340, contains the radioactive elements americium and cesium, which emit gamma radiation that can burn the skin.
Cpl. Cheryl Bush said the device should have a warning sticker on it stating that it is radioactive.
Anyone who finds the device, or knows of its whereabouts, should call the RCMP.
