Detailed Discussion:
Per the attached Situational Awareness Report, issued today, the Department of Homeland Security’s Domestic Nuclear Detection Office Joint Analysis Center advises on an alert issued for several Mexican states following the theft of “potentially deadly radioactive material used for industrial radiography.”
The alert, issued by the Mexican Interior Ministry, follows the theft of a truck transporting an INC 100 radiography camera in Cardenas, in the southern state of Tabasco
The camera contains Iridium-192 radioactive source material. An image of the camera type follows:

Per the DNDO bulletin, citing the US Centers for Disease Control, “Iridium-192 is a manmade radioactive element that can cause burns, acute radiation sickness and even death.”
The material is used in “cancer treatment or in industrial gauges that inspect welding seams.”
The Interior Ministry alert has been issued to federal police, military branches (Army and Navy), and civil protection authorities in Tabasco, Campeche, Chiapas, Oaxaca, and Veracruz – states in the country’s southeastern region.
Mexico’s National Civil Protection Coordinator has warned via Twitter posting that anyone who finds this device should “not handle or stay close to it.”
If it is located, an approximately 100-foot perimeter should be established with immediate contact to law enforcement authorities for coordinated response.
