DENVER—A common engineering gauge with a radiation source was stolen from the back of a pickup truck outside a residence in Denver between Monday, July 30, and Thursday, Aug. 2.
The radioactive materials contained in the gauge do not present a significant health risk to traffic or pedestrians as long as the gauge remains intact and is not handled for long periods. Higher radiation exposures may occur if the radioactive sources are tampered with or the source rod is moved from its shielded position.
The gauge was reported stolen to the Radiation Program at the Colorado Department of Public Health and Environment on Aug. 2. The gauge belongs to A. G. Wassenaar, Inc. of Denver.
The company reports the instrument is a Troxler 3430 Surface Moisture Density Gauge. The gauge was inside its storage/transportation box. (See images below.)The hard plastic box is cooler-sized and bright yellow.
A.G. Wassenaar is offering a reward for the return of the gauge. For more information, please contact Patrick Kernan at 303-944-4222. Anyone finding the gauge or gauge transport case should immediately notify the Colorado Department of Public Health at 303-877-9757.
