In the wake of escalating radiation fears brought on by the Fukushima Dai-ichi nuclear power plant crisis, Haneda and Narita airports have created public web pages with twice-daily updates on radiation levels near their facilities.
Emphasizing the continuing safety of the areas, and with the goal of curtailing misinformed rumors, the two sites update the radiation level at 9 a.m. and 9 p.m. in both English and Japanese.
Narita airport set up its detector in Hokotashi, Ibaraki Prefecture, some 50 kilometers from the airport, while Haneda's detector transmits from nearby Kawasaki city. As of Monday at 9 p.m., the reading near Narita airport was 0.95 millisieverts per year, and 0.39 millisieverts per year near Haneda. Both are actually below the world average exposure of 2.4 millisieverts per year.
Japan's foreign ministry has emphasized that the level is far below anything considered harmful to human health.
