Radioactivity (JAPAN)

The risk to the plate
Radioactivity is in Japan not only in the air. Meanwhile, appear more and more contaminated food. This means that soil and groundwater are contaminated.
The bad news do not tear off: Does it even know the situation in the risk-reactors had stabilized, the message is a few hours later, reenter it from smoke, the work must be to protect high-risk employees and firefighters will be interrupted. Now the danger zone extends beyond the 30-kilometer radius from around Fukushima. For the first time it was announced that some foods tested were well above the allowable limit of radioactivity.
Values ​​27 times above the upper limit Sadly runner is Spinach: In more than 100 kilometers away from the scene of the accident he was still under pressure. Samples at Hitachi, 100 kilometers south of Fukushima showed a kilogram of green leaf vegetables up to 54 000 Bq radioactive iodine. This value is 27 times higher than the permissible limit. The cesium content was 1931 becquerels per kilogram. Becquerel is the decay of an atom per second, is free with any radioactive decay - the total amount is then summarized in Becquerel and reflects the amount of radiation. The normal acceptable limits in Japan are located at 2000 becquerels of iodine-131 and at 500 becquerels of cesium.
Radioactively contaminated spinach, it was not. Also, milk samples from surrounding areas around Fukushima brought increased values. The International Atomic Energy Agency reported in milk from the region of Fukushima iodine-131 levels 900-1500 becquerels per liter. However, the limit is reached first at 2,000 becquerels per liter. The natural radioactivity content in milk is 40 to 60 becquerels per liter. Spring onions in the test showed peaks up to 6100 becquerels per kilogram. Therefore, an appeal was taken by officials to farmers on good governance with a request not to bring in contaminated food trade. For four prefectures of the government imposed a ban on delivery of milk and several vegetables.
Unclear consequences for fish The problem for Japanese farmers to happen rather quickly solve. For their livestock needs food - they have it but graze on the pasture, it takes so on radioactivity, which are then deposited in the milk and meat.
To what extent fish from the Pacific is concerned, is still unclear. The radiation biologist Edmund Lengfelder but warns against a load, particularly for the Japanese people, this is very much fish could be risky. Other voices assume, however, that radioactive particles that enter the sea via precipitation spread there so far that hardly could be expected alarming readings.
