An engineering instrument containing a small amount of radioactive material was stolen in the Denver Area last week. The tool uses the radiation source for measuring the moisture and density of soils or other materials.
The tool is a Troxler 3430 Surface Moisture Density Gauge, which was inside a hard plastic box. The box was bright yellow and about the size of the cooler.
It was stolen from the back of a pickup truck outside a home in the Denver area between Monday, July 30, and Thursday, Aug. 2. The tool belongs to A. G. Wassenaar, Inc. of Denver.
A.G. Wassenaar is offering a reward for the return of the gauge. Anyone with information should contact Patrick Kernan at 303-944-4222 or the Colorado Department of Public Health at 303-877-9757.
