What is the Japan radiation health risk?

Radiation levels have fallen at Japan's earthquake-stricken Fukushima Daiichi nuclear plant, the government says.

The levels had spiked to harmful levels after a fire and two more explosions at the site.

Weather reports say winds are blowing radiation from the plant, on Japan's north-east coast, over the Pacific.

It is still the case that people are having to exercise great care and take shelter across a wide area.
