In 1997 a significant meeting sponsored by the Council of Scientific Society Presidents, with many other co-sponsors, gathered noted authorities at Racine, WI (Wingspread Conference 1997). One of the significant conclusions of this conference was that "A substantial body of scientific evidence demonstrates statistically significant increases in cancer incidence for acute whole-body exposures of adults to ionizing radiation at doses of about 10 rem and greater." This implies that a substantial body of scientific evidence for cancer incidence DOESN'T exist for acute exposures below 10 rem.
