Authorities are asking for the public TMs help in finding potentially dangerous radioactive materials stolen from an oil and gas exploration truck in Alice.
The Texas Department of State Health Services (DSHS) reported that the theft of the nuclear materials took place on Friday night.
Investigators said six lead containers containing the radioactive materials were kept in a clear plastic bag placed inside the truck TMs toolbox.
Each metal container is shrink-wrapped and contains a glass vial of ceramic granules called radioactive tracer sand used by ProTechnics, a Houston-based oil and gas exploration company.
The company's truck was parked outside the Walmart store in Alice at the time of the alleged theft.
The company is offering a $1,000 reward for information leading to the recovery of the containers.
DSHS officials said a person handling the containers or the sand could be at risk of radiation exposure.
Anyone with information on the whereabouts of the radioactive materials is asked to call their local police or sheriff TMs department or DSHS at (512) 458-7460.
