Japan quake: Nuclear fears cause dilemma for Tokyo residents

In Japan, water is still being pumped into the overheating reactors at the nuclear power plant at Fukushima.

An attempt to drop water in from helicopters has been abandoned, because of high radiation levels.

The International Atomic Energy Authority says radiation levels have increased slightly in the capital, Tokyo, 220km to the south, but that they are "not dangerous to human health".

This has not stopped some people choosing to leave the city, as the BBC's Max Pearson reports.
