Japan in hot water

Twenty tonnes of radioactive water last week leaked from a cracked pipe at
the Tsuruga power station, 300 kilometres northwest of Tokyo. Around 46 000
becquerels of radiation flooded from the 8 centimetre-long fissure in a coolant
pipe—11 500 times the legal limit. Although the leak was contained within
the plant, cleanup workers were allowed to spend only three hours a day in the
area.
