More than 80 tons of radioactive manganese ore was refused entry

        Recently, under the supervision of Lianyungang customs officers, a cargo ship carrying more than 80 tons of manganese ore slowly left the Lianyungang wharf. The batch of imported manganese ore with excessive radioactivity was successfully returned to the country.

　　 During the inspection process, Lianyungang Customs inspectors conducted on-site inspections of the batch of manganese ore. When they approached the container carrying the cargo, the portable radiation monitor carried by the customs officer began to alarm, and the instrument showed that the batch of cargo had excessive radiation. Immediately, customs officers carried out on-site inspections and found that the γ-ray dose equivalent rate of this batch of goods exceeded the background 35 times, which did not meet my country's environmental standards. The on-site customs officers quickly sampled the batch of goods and sent them for inspection. isolation. After laboratory testing, the radioactive activity concentration of radium-226 and uranium-238 in this batch of goods far exceeded the limit standard set by the state, and Lianyungang Customs ordered the return shipment according to law.

          According to the application data, the imported manganese ore will be used for alloy smelting to produce ferromanganese, silico-manganese and other products, which will be used in gold, battery, alloy and other industries. Once more than 80 tons of manganese ore exceeding the standard radiation flow into the domestic market, It may cause harm to people who come into contact with it. In addition, radioactive materials are difficult to destroy and can cause long-term pollution to the environment and water quality, and threaten humans, animals and plants.
