Japan earthquake: The search for 'contaminated' bodies
Japan's air force is stepping up the search to find the bodies of the tsunami victims in the north east of the country.

It may take 30 years for the area around Fukushima to become fully habitable again, Professor Itaru Yasui of Tokyo University has said.
