The International Atomic Energy Agency (IAEA) also raised concerns about a lack of information from Japanese authorities, as workers battling to cool the nuclear reactors faced rising temperatures around the core of one reactor.
"We continue to see radiation coming from the site ... and the question is where exactly is that coming from?" James Lyons, a senior official of the International Atomic Energy Agency (IAEA), told a news conference in Vienna on Tuesday.
