(Reuters) - Angry parents of children in Japan's Fukushima city marched along with hundreds of people on Sunday to demand protection for their children from radiation more than three months after a massive quake and tsunami triggered the worst nuclear disaster in 25 years.

"We want our lives back, we want to live like before the quake in happy families," said Hiroko Sato who marched in heavy rain with her nephews, age 3 and 7, next to banners saying "No Nukes" and "One Fukushima is Enough." "My baby was born two weeks before the nuclear accident and I don't feed her with my milk as I'm afraid I was exposed to too much radiation," said Sato.

Three reactors went into meltdown after the earthquake hit the Fukushima Daiichi power plant in northeastern Japan on March 11, forcing 80,000 residents to evacuate from its vicinity as engineers battled radiation leaks, hydrogen explosions and overheating fuel rods.
