TOKYO- Radiation released by the damaged reactors at Fukushima No 1 nuclear power plant has been high enough to threat human health, said the Japanese government on Tuesday.
An explosion was heard early Tuesday morning at the No 2 reactor of the crippled plant and a fire has just been reported at the No 4 reactor, causing more radiation near the complex.
Prime Minister Naoto Kan warned that further leaks are possible and told people living within a radius of 30 kilometers of the troubled plant to stay indoors.
