I am glad that you and your friend are trying to do good things for the people of Japan that have been devastated by this tragedy. You do indeed have a voice. You should, however, as Henrikoolsen and Fushigifox have previously stated ensure that the people that are getting this information know what it means. There are already too many people who are ignorant of the physics of radiation that try to use any statistic they can get their hands on to push their own agenda. I hope that your friend is able to help without being exploited.
