Abstract: Two incidents involving the seizure of contaminated shipments of metals originating in Kazakhstan were reported by Uzbek authorities on 11 May 2006. In the first incident, a shipment of zinc contaminated with radiation, was seized after it triggered a radiation monitor at a Bukhara Oblast customs checkpoint. 15,386kg of zinc powder and oxidized zinc containing traces of cesium-137 were in transit from Kazakhstan to Iran. At a distance of 1.5m the radiation emitted by the material was 240-300 microroentgen/hour, while the naturally occurring background level in that area is 17-20 microroentgen/hour. According to Regnum.ru, any shipment contaminated by cesium-137 is classified as "hazardous cargo" by the Uzbek law on waste and requires a transit permit approved by the Cabinet of Ministers of Uzbekistan. In an attempt to conceal the nature of the cargo, Casting shipping company used falsified documentation. In another incident, customs officers in Tashkent Oblast seized a train shipment of molybdenum contaminated with radioactive substances such as radium-226, uranium-234, uranium-238, and thorium-234. This shipment was en route from Kazakhstan to Tajikistan. The date of this seizure was not indicated in the media reports. Uzbek law enforcement authorities have opened criminal investigations into both incidents. {Entered 10/08/06 RN}
