Via Kyodo News :
" Japan on Sunday faced an increasing challenge of removing highly radioactive water found inside buildings near some troubled nuclear reactors at the Fukushima Daiichi plant, with the radiation level of the surface of the pool in the basement of the No. 2 reactor's turbine building found to be more than 1,000 millisieverts per hour.
Exposure to such an environment for four hours would raise the risk of dying in 30 days. Hidehiko Nishiyama, spokesman for the government's nuclear safety agency, said the figure is ''quite high'' but authorities must find a way to pump out the water without sending workers too close to push ahead with the restoration work.
Plant operator Tokyo Electric Power Co. said early Monday the concentration of radioactive substances of the puddle was 100,000 times higher than that usually measured in water in a reactor core, correcting its earlier analysis of 10 million times higher.
Adding to the woes is the increasing level of contamination in the sea near the plant, although Nishiyama reiterated there is no need for health concerns so far because fishing would not be conducted in the evacuation-designated area within 20 kilometers of the plant and radioactive materials ''will be significantly diluted'' by the time they are consumed by marine species and then by people.
Radioactive iodine-131 at a concentration 1,850.5 times the legal limit was detected in a seawater sample taken Saturday around 330 meters south of the plant, near a drainage outlet of the four troubled reactors, compared with 1,250.8 times the limit found Friday, the agency said."
