PITTSBURGH - Police and the Pennsylvania Department of Environmental Protection are searching for a missing portable gauge that contains sealed radioactive material.
The DEP said the device isn't a hazard as long as it is not tampered with or damaged.
The Troxler gauge belongs to Pittsburgh-based Solar Testing of Pennsylvania. It was last used on Friday in the Mount Lebanon area, and the company is offering a $500 reward for information leading to its recovery.
DEP investigators are inspecting the facility where it is usually stored and interviewing management and employees.
The gauge is yellow and about the size of a shoe box, with an electronic keypad and a metal rod extending from the top surface. It contains radioactive cesium-137 and americium-241.
