The Japanese nuclear radiation will affect food security

 in March, 2011, outside the Japanese Fudao first nuclear power station's radioactive substance releases, causes the nuclear power station nearby vegetables, the fruit, the paddy rice, the meats, the fish and so on each kind of food to be polluted radioactive substance. Statistics indicated that Japan exports food to account for the world food export total quantity every year 5%, majority is the processed food and the seafood class. Freely, this proportion does not calculate in a big way, but if in a these food's part has been polluted, also will give world food to bring the threat safely. Then, this Japanese nuclear radiation actually how will affect food security? 
 In Fudao first nuclear power station accident, because the nuclear fuel stick has not obtained cooling to have the fuse, creates outside the massive radioactive substance leisurely to the environment, like radioactive substance cesium - 137, iodines - 131 and strontium. These radioactive substance descends on the nuclear power station land, or gathers along with the steam in the cloud layer, falls the ground through the rainfall, has polluted the soil, the pasture, the water source as well as the crops. The radioactive substance scatters with the wind, affects a scope broader region, has polluted the local water source and food.

  After the accident, the Japanese government requests 47 provinces the related departments to monitor its respective place food security, including: Vegetables, fruit, meats, water source, seafood and so on. After the examination, the Japanese government discovered around the nuclear power station the province produces in milk and spinach radioactive iodine and cesium exceeding the allowed figure. According to the normal level, iodine - 131 cannot be higher than 2000 Baker/kilograms in the vegetables content, but the cesium content cannot surpass 500 Baker/kilograms, but in is away from the Fudao nuclear power station 97 kilometer Hitachi cities, food department examines in the spinach the radioactive iodine and the cesium surpasses the normal level 27 times. Moreover, Japanese Fudao, Cicheng, Limu and Qunma County produce the milk radioactive substance also surpasses the normal level.

  Many countries worried that Japan's radioactive substance can cross the seas to cross ocean affects our country food security, or in pollution sea fish. About this point, the scientist confirmed that the Japanese Fudao nuclear power station dissipation's radioactive substance total quantity is insufficient to create the big area the marine pollution, after radioactive substance by sea water dilution, its can produce the influence was already miniscule.but

, the Fudao nuclear power station nearby land will receive a more serious pollution, its production's food will be no longer safe.
