Fukushima, which lies 130 miles north east of Tokyo, is home to The Fukushima I (Daiichi) Nuclear Power Plant which consists of six light water, boiling water reactors. The power plant is one of the 25 largest nuclear power plants in the world.
There were no deaths caused by radiation exposure, while approximately 18,500 people died due to the earthquake and tsunami. The local fishermen became suspicious of the possible leaking of radioactive water which was taking place after the incident, which was later confirmed in July 2013, over two years later.
On 20th August 2013, in a further incident, it was announced that 300 tonnes of heavily contaminated water had leaked from a storage tank. The water was radioactive enough to be hazardous to nearby staff, and the leak was assessed as Level 3 on the International Nuclear Event Scale.
Masayuki Ono, general manager of Tokyo Electric Power Company (Tepco) which runs the plant, said: “We found a radiation level strong enough to give someone a five-year dose of radiation within one hour.”
