Japan earthquake: Radiation tests in Fukushima schools

Officials in the Fukushima region of Japan have started an emergency programme to measure radiation levels in school playgrounds.

More than 1,400 schools and nurseries will be tested over two days to try and calm anxiety among parents following leaks at the Fukushima Daiichi nuclear plant.

The plant was crippled by last month's earthquake and tsunami.

Officials say there should be no risk to children if they keep outside a 30km (19mile) exclusion zone.
