Experts from the International Atomic Energy Agency have arrived in the Japanese city of Fukushima to observe the massive decontamination effort under way after the world's worst nuclear disaster since Chernobyl.
The 12-member IAEA group arrived this morning and plans to visit farms, schools and government offices throughout Fukushima prefecture in north-eastern Japan.
It is the second major IAEA mission to Japan since the nuclear crisis began.
Nearly 20,000 people were killed when the earthquake and tsunami hit Japan on March 11
The disaster severely damaged the Fukushima plant.
Officials say the plant is now relatively stable, but tens of thousands of people still cannot return to their homes because of the radioactive contamination.
