It is noted that cows live in conditions of radiation. Before the disaster at the "Fukushima-1" there were agricultural lands, inhabited by more than 3,500 Pets. After the accident at units in the vicinity of the NPP have only 200 cows, which for radiobiological research. Scientists from universities in Iwate Prefecture, and Tokai, Shibasaburo take samples of blood and urine, and check the volume of the lymph nodes every three months.

According to scientists, the government of Japan believes the study is meaningless because it was not specified which dose of ionizing radiation the animals received after the disaster. However, researchers are confident that the results of their work will show whether the farmers in the future to work on the victims of radiation contamination territories.

It was found that internal organs of animals, including those that belong to the reproductive system, while not affected by chronic exposure. Nevertheless, the work is meant believe that it is impossible to make premature conclusions, as, for example, thyroid cancer and leukaemia may develop some years later.
