Radiation hazard at Fukushima-1 was raised to the third level on INES scale. The level means that radioactivity may spread, posing hazard to the environment. Moreover, it may affect personnel inside the nuclear power plant. Prior to that, Fukushima recorded the lowest possible level of risk.
The level of contamination of water that flows into the Pacific Ocean waters is extremely high. A person, who stays near the contaminated water for an hour, receives a dose of radiation that exceeds the acceptable level of radiation that employees of nuclear power plants get in one year.
In the Japanese prefecture of Fukushima, the number of cases of thyroid cancer has increased six times. Eighteen cases of the disease have been reported among minors. Experts intend to study each of the cases of cancer in detail to find out whether they were caused by radiation.
