Fukushima Daiichi was a nuclear power plant in Japan that was damage by a 15-meter tsunami which cause the cores of the plant to melt and release high radioactive contamination.

One of the reason the problem escalated is that the Japanese downplay the dangers by increasing the the safe radiation exposure level from 1 mSv (millisievert which is the radiation exposure of an individual for 1 year which is 1mSv) to 20 mSv per year which prevented the evacuation of many contaminated areas.

The areas far from the plant were also contaminated because of the rain, snow, and flow of water from the tsunami because of these unfortunate events, the decontamination failed.

Some of the consequences are that the radioactive waste enters the ecosystem, polluting water, soil, plants and animals. The consumption of any items contaminated accumulate in the heart, kidneys, small intestines, pancreas, spleen and liver. This accumulation is more rapid and dangerous for children.

The contamination was not only limited to land but also to the ocean. Months after the incidents, fish caught near Japan coast were found to be also contaminated,

Here is video about the current situation of the plants:
