Japan has announced plans to decommission four reactors at the earthquake-hit Fukushima Daiichi nuclear power station. Emergency crews have failed to control reactors Units 1 to 4 since they were struck in the earthquake and tsunami earlier this month. The announcement comes as seawater near the plant is showing the highest levels of radiation to date. Nuclear safety officials report seawater 300 yards outside the Fukushima facility contains more than 3,000 times the legal limit for the amount of radioactive iodine, indicating both the highest levels of radiation found so far and the fact that contaminated water is making its way into the ocean. Radiation has also seeped into the soil, produce, raw milk and even Tokyo’s tap water some 140 miles south of the facility. The president of Tokyo Electric Power Company, meanwhile, has been admitted to a Tokyo hospital for hypertension, after suffering from dizziness and high blood pressure.
