DENVER (CBS4) – A reward is out for a stolen engineering gauge which could put people at risk for radiation exposure.

The Colorado Department of Health shared images of what the gauge looks like on Monday. It contains radioactive material, which normally is not a risk, but could become dangerous if someone tampers with it.

The gauge, described as a Troxler 3430 Surface Moisture Density Gauge, was in a cooler sized container.
