After the accident at the plant "Fukushima-1", occurred in 2011, it was revealed that the 18 children living in this area, thyroid cancer, TV channel NHK World.
After the incident, the state of emergency was surveyed over two hundred children, and 25 cases were found pathological changes in the thyroid gland. This was the beginning of the mass scan of the citizens of Japan, which is expected to affect more than 360 thousand people.
Scientists of the Medical University Fukushima Prefecture suggest that the increase in the incidence of thyroid cancer is not directly associated with the accident at the plant. Changes that occur in the body usually occur only after 4-5 years. However, it was decided to establish a Commission to monitor the health of citizens and detect disease at early stages.
Scientists from European countries included in the world health organization (who) confirms that the sharp increase cancer incidence under the action of radiation should not be. A person living in the area with the normal level of radiation, the chance of getting cancer of the thyroid gland - 0,76% in women of 0.21% in men, and the people who were in the area of Fukushima - 0,85% and 0.23%.
Recently THURSO, the operator of the Fukushima-1", told about the major leakage of radiation through the water. Leakage is considered to be the largest after the explosion in 2011 and 300 tons of water. The level of radiation sources increased slightly, which gave grounds to assign the situation first severity on a scale radiological and nuclear events. The Committee, however, does not exclude the possibility of raising the threat level to the third level on the INES scale.
Currently, the assessment of background radiation showed that doses of 50-100 Gy have minimal chance to provoke the development of thyroid cancer. It should also be noted that the accident at Chernobyl in 1986 and further monitoring of the level of cancer incidence did not indicate an Association between exposure to radiation and the occurrence of tumors of different localization.
The accident at the "Fukushima-1" occurred in March 2011 earthquake. The quake caused a tsunami, which covered four reactors, resulting in water dramatically increased the level of radiation. This accident was the largest in 25 years, and lost on the scale only to the explosion at the Chernobyl nuclear power plant.
