To whom does scientific debate belong?

That was a central question raised by many of the 200-plus people who attended a citizens' forum in Tokyo on Oct. 12, as they criticized the ways in which the Japanese government and radiation specialists working for it are assessing and monitoring the health effects of the ongoing nuclear disaster at the Fukushima No. 1 nuclear power plant.

The daylong conference, organized by the Japanese citizens' groups SAY-Peace Project and Citizens' Radioactivity Measuring Station (CRMS), featured experts who dispute much of the evidence on which the government has based its health and welfare decisions affecting residents of Fukushima Prefecture and beyond.
