The sources, which were apparently used by the Soviet military in training exercises, were first discovered by accident in 1997 when Georgian soldiers at a former Soviet military base started developing severe radiation burns. At first, authorities were unable to determine the cause of the wounds. But after an extensive investigation, several small cesium 137 sources were found buried in various spots around the base. According to Abel Gonzalez, head of Nuclear Safety and Waste at the International Atomic Energy Agency, when the Russian military abandoned the base in 1992, they left behind scores of these radiation sources and failed to tell anyone in Georgia about them. So may I can't quantify them.
Nobody knows what's going on in the former Soviet Union.
But the Russians tell me that they think the situation is disastrous.
