THORNTON - The Colorado Department of Public Health and Environment announced today that a portable moisture density gauge containing radioactive materials that was reported stolen in Thornton over the weekend has been recovered.
The Thornton Police Department notified state officials that the instrument was recovered last night. Suspects are in custody, and a criminal investigation is under way. The Troxler model 3430 density gauge measures moisture and compaction in soil, asphalt and concrete.
Martinez Associates, LLC, of Denver, reported the gauge was stolen from a vehicle parked at an apartment complex at 8901 Grant St. on Sunday evening.
The department's Radiation Program is investigating to determine if violations of the company's radioactive materials license occurred.
