It has been asserted that the investigation on late radiation effects by the Atomic Bomb Casualty Cornmission (ABCC) and the Radiation Effects Research Foundation (RERF) is the one and only exhaustive study for more than thirty years among the one hundred thousand atomic bomb survivors. However, their studies had some principal problems which lead inevitably serious underestimations of radiation effects on human body. On the starting point of the research, ABCC made an exception of the period from December 1945 till September 1950, concealing the fact that the death rate especially among the high level radiation survivors was extremely high at the period. ABCC also excluded such survivors from the research as those who resided out of the cities of Hiroshima and Nagasaki in October, 1950 because of the time lag of the reconstructions of their houses around ground zero. Morever, ABCC cut out the most of young survivors who migrated out of the cities before 1950. Their late cancer deaths should surely have raised its rate among the survivors, if ABCC investigated them. The cancer risk of radiation exposure was estimated among these biased atomic bomb survivors by ABCC, and was substantially underestimated. Its risk factor should be thoroughly reevaluated from the point of reestimation not only of the atomic bomb radiation doses, but of the fundamental date obtained by ABCC and RERF.
