CANCER RISK IN X-RAY TECHNOLOGISTS

明尼苏达大学已经与国家癌症协会签订了合同 评估近145,000名工人的健康状况 自1982年以来一直是美国放射技术专家注册机构。一个 综合基线调查完成9万多人 1984年至之间的技术人员。第二项调查正在进行中，以获得 自第一次调查以来诊断出的癌症的详细信息。这个 这份合同的目标是完成和扩大癌症的调查 美国X射线技术人员的发病率，并量化 与职业辐射暴露有关的特定癌症。 生物剂量学技术的广泛应用将被用于 确定辐射暴露的特征。此外，可能扮演的角色是 遗传易感性可能在辐射诱发的癌症中发挥作用 在35岁以下患乳腺癌的女性中进行评估。

The University of Minnesota has been under contract to the National Cancer Institute in evaluating the health of nearly 145,000 workers certified by the American Registry of Radiologic Technologists since 1982. A comprehensive baseline survey was completed by more than 90,000 technologists between 1984-1989. A second survey is ongoing to obtain detailed information on cancers diagnosed since the first survey. The objectives of this contract are to complete and extend the survey of cancer incidence among U.S. x-ray technologists and to quantify the risk of specific cancers associated with occupational radiation exposures. Extensive application of biological dosimetry techniques will be used to characterize radiation exposures. In addition, the possible role that genetic susceptibility may play in radiation-induced cancers will be evaluated among women who developed breast cancer under the age of 35.
