Using data from the Tri-State and a mathematical model, the hypothesis that low levels of diagnostic radiation can produce both leukemia and heart disease has been tested. The range of radiation considered is within a factor of 10 of 5 rads (0.5-50 rads). Even at the lowest levels, an estimated 5% of the persons exposed suffer damage to the DNA which is subsequently expressed as heart disease or leukemia. The risk of heart disease in an affected group is roughly tripled and there is a 10-fold increase in the risk of leukemia according to preliminary estimates.
利用三州地区的数据和一个数学模型，对低剂量诊断性辐射会导致白血病和心脏病这一假设进行了检验。所考虑的辐射范围在5拉德的10倍以内（0.5 - 50拉德）。即使在最低剂量水平下，估计有5%的受辐射者会出现DNA损伤，随后表现为心脏病或白血病。根据初步估计，受影响群体患心脏病的风险大约增加两倍，患白血病的风险增加10倍。
