Radioactive material stolen from lab in Mexico
A device containing radioactive substances [cesium-37 and americium-beryllium] was stolen from a government research facility and authorities are working to track it down, Mexico's No. 2 official said. "We have the report regarding the theft of this material and the alerts and protocol we follow in these cases have already been implemented," Government Secretary Miguel Angel Osorio Chong told reporters after speaking at a conference of state law enforcement chiefs and attorneys general. A group of armed men grabbed the device Sunday night during an assault on a National Construction Laboratory warehouse in Tultitlan, Mexico state.
