| Research Abstract |
Even at low and very low dose categories, the Hiroshima A-bomb survivors were significantly high for all cancers, solid cancers, and liver cancers in male subjects, and for uterus and liver cancers in female subjects, respectively. RERF researchers have not used true non-exposed control. Conducting a risk analysis without a genuine non-exposed group does not do justice to RERF's valuable data. We recommend that RERF should look at new research results, and change their fundamental research model by establishing a non-exposed control group. We calculated the SMRs for the A-bomb survivors versus all Japan children as a true non-exposed group. A notable result was that SMRs in boys exposed to low doses were significantly higher for soid cancer.
