A case-control study of 112 households residing in the vicinity of a thorium waste disposal site found a higher prevalence of birth defects (RR 2.1) and liver diseases (RR 2.3) among exposed than the unexposed group. The numbers were quite small and the confidence intervals wide, however, so that no definite conclusions can be drawn from these data.
一项针对居住在钍废物处置场附近的112户家庭的病例对照研究发现,与未暴露组相比,暴露组的出生缺陷患病率(相对危险度为2.1)和肝脏疾病患病率(相对危险度为2.3)更高。然而,研究对象数量相当少,置信区间也很宽,因此无法从这些数据中得出明确结论。
