Gauge containing radioactive sources still missing; reward offered
DENVER – A portable gauge that uses radioactivity to test moisture density at construction sites is still missing. A $1,000 reward is offered for information leading to its return. A.G. Wassenaar Inc., of Denver, reported the gauge missing on Friday, April 11. It was lost somewhere between the intersection of Shaffer Parkway and Shaffer Place and the intersection of West Ken Caryl Avenue and South Continental Divide Road in Jefferson County.
The device, a Troxler model 3430 density gauge, serial number 36856, has two radioactive sources: Cesium-137 and a combination of Americium-241 and Beryllium. The gauge presents a potential health risk if handled improperly. The gauge is a yellow metal box featuring a long, rod-shaped handle with a grip. A radioactive warning label is attached to the handle and the case. The top of the device features a keypad and electronic display. The instrument is safe if it is intact and handled by appropriately trained people, but could emit higher-than-normal levels of radiation if the shielding is damaged. There was no carrying case with the missing gauge.
Anyone who finds the device should not handle it, but should immediately call the company’s radiation safety officer at 303-210-2297.
Part of the Hazardous Materials and Waste Management Division, the Radiation Program regulates the possession, use, management and disposal of radioactive materials and regulates radiation-producing machinery such as X-ray machines. The program also works with local agencies to provide information regarding radon levels in homes and other buildings.
