Japanese engineers are struggling to pump radioactive water from around six reactors at the Fukushima nuclear plant.
They are now using fresh water rather than sea water to try to cool them down. High radioactivity levels in the sea around the facility remain a concern, but the government is assuring the public that they will remain vigilant.
Japanese Chief Cabinet Secretary Yukio Edan said: “As of now, there’s no report of any adverse impact on the marine life, especially beyond 20km. Experts say there’s a very low possibility, but we must increase our monitoring.”
Greenpeace radiation experts are investigating the risk to locals living near the plant, checking radiation levels outside of the official evacuation zone.
One of the organisation’s nuclear campaigners, Jan Vande Putte, said: “Here at Tsushima, which is about 35km from the nuclear power reactor of Fukushima, radiation levels are really high. People living here would receive a maximum annual dose in about four days. That is really unacceptable. People should be evacuated from this area.”
Japanese authorities have measured radioactive iodine levels in the sea around the plant 1,850 times higher than normal.
