High radiation levels threat to human health: Japanese government

Via The Globe and Mail, excerpt :

" Japan faced the growing possibility of serious radiation leaks – maybe even a catastrophic meltdown – after two more explosions rocked a nuclear power plant and workers were forced to abandon the most dangerous reactor, which suffered damage to its containment structure.

The government warned Tuesday of an alarming radiation leak from the stricken nuclear power plant and told people nearby to stay indoors to avoid becoming sick in a rapidly escalating national crisis following last week's earthquake and tsunami.

In a nationally televised statement, Prime Minister Naoto Kan said radiation has spread from the three reactors of the Fukushima Dai-ichi nuclear plant in one of the hardest-hit provinces in Friday's 9.0-magnitude earthquake and the ensuing tsunami."
