TOKYO: Japanese officials are handing out radiation-blocking iodine tablets to people living in the shadow of two nuclear reactors slated to restart this year, underscoring concerns about atomic power after the Fukushima crisis. The move to distribute the pills — which help to reduce radiation buildup in the body — started on Sunday for those living within a five-kilometer (three-mile) radius of the Sendai nuclear plant. The site, roughly 1,000 kilometers from Tokyo on the southern island of Kyushu, recently cleared new safety standards and could start operations in a few months. It comes despite vocal opposition to the plan, three years after the worst atomic crisis in a generation. Japan’s Nuclear Regulation Authority said earlier this month that two atomic reactors at the Sendai plant were safe enough to switch back on, marking a big step towards restarting nuclear plants which were shuttered after Fukushima.
