Using BEIR V risk estimates and age-specific population dose estimates, we estimate that approximately 12% of leukemias may be attributable to diagnostic x-rays. Earlier estimates were markedly lower (< or = 1%) because of their use of earlier risk coefficients, different dose rate effectiveness factors, and, in one case, a methodological error.
利用BEIR V风险估计值和特定年龄的人群剂量估计值,我们估计约12%的白血病可能归因于诊断性X光检查。早期的估计值明显更低(≤1%),这是因为使用了早期的风险系数、不同的剂量率有效性因子,并且在一个案例中还存在方法学错误。
