After Fukushima Daiichi Nuclear Power Plant accident happened on 11 March 2011, we have been providing the right information about radiation and radioactivity via a Q&A website. Immediately after the accident, volunteers of Japan Health Physics Society (JHPS) built up a website named Questions and Answers about Radiation in Daily Life. They carefully answered all of the questions posted on the website. In August, Steering Committee of the Q&A site was officially established in JHPS. Since then, the Committee has been engaged in the risk communication activities to the public. We have analyzed characteristics of questioners and question contents of about 1,500 posted on our web site so far. It has been found that mothers of small children form the major portion of the questioners all through the period.
