<p>Japanese children can now be exposed to 20 times the radiation that was permissible before the March 11 tsunami caused a meltdown at the Fukushima nuclear plant, sparking the world's worst nuclear crisis since Chernobyl.<br /><br />Around 400 protesters, many from areas around the stricken plant, flocked to the education and science ministry to demand a rethink on the new limit, which allows exposure of up to 20 millisieverts a year.<br /><br />A group of Fukushima residents submitted a letter for the education minister demanding the ministry do all it can to lower radiation levels at schools and offer financial support.<br /><br />Protest organisers said the radiation limit for playgrounds was about six times as much as the 0.6 microsievert-per-hour legal maximum under which under-18s are allowed to work.<br /><br />Demonstrators brandished banners emblazoned with slogans such as "Protect children in Fukushima from radiation" and chanted: "Why is it 20 millisieverts? Come out minister!"<br />Ministers have defended the increase in the acceptable safety level as a necessary measure to guarantee the education of thousands of children in Fukushima prefecture.<br /><br />Science minister Yoshiaki Takaki had earlier told a parliamentary session: "We are always thinking that we should never underestimate the risk of radiation."<br /><br />"Efforts have to be made in order to avoid radiation as much as possible," he said.<br /><br />But the demonstrators were not placated.<br /><br />"This is enough. I'm really furious to see the government has no intention of protecting its people," said Ruiko Muto, 57, who had journeyed from Miharu town, about 45 kilometres (28 miles) from the crippled plant.<br /><br />"We are making the demand in order to protect children, as Fukushima's education authorities are following the guidelines and saying outside activities can be safe."<br /><br />The nuclear crisis remains unresolved and tens of thousands of people are still unable to return to homes, farms and businesses in a 20-kilometre zone around the radiation-spewing plant.<br /><br />More than 20 elementary and junior high schools within 30 kilometres have been forced to close since the accident, affecting some 5,000 pupils, the Yomiuri daily newspaper reported today. <br /><br /></p>
