Kubanych Noruzbaev, an official from the Kyrgyz Ecology and Environmental Protection Ministry, said on January 10 that the material was cesium-137, a product of nuclear reactors and weapons testing that is often used in medical devices and gauges. But it could also be used in a crude radioactive explosive device -- a "dirty bomb" -- and underscores the fact that despite some progress since 1991, parts of the former Soviet Union are still littered with sites where lethal radioactive materials remain largely unsecured.
The Kyrgyz news agency 24.kg reported on January 9 that the levels of radiation being emitted from the train car were so high that the Emergency Situations Ministry asked for volunteers to go and unload the cargo. Four people wearing special protective clothing volunteered to venture into the wagon where they discovered the source of the radiation: dust and waste material on the floor, which they swept up and deposited in a bucket. The bucket was then sealed in concrete and stored in a special facility.
Reports say the material emitted 1,000 milliroentgen per hour, which is considered a dangerous level. Most companies handling such material consider 5,000 milliroentgen per 2,000-hour work year to be the "regulatory upper limit" for safety.
"It emits radiation, radioactive waves, and they are harmful, maybe not in mediocre amounts but prolonged exposure," Noruzbaev said. "If you held it a while, depending on the dosage, you would get burns of varying degrees."
