前言 虽然医疗照射量小,但确对患者健康有害,因而有关的调查研究已成为医疗实践的重要部分。在英国每年估计有100—250例癌症患者的死亡与医疗照射直接相关。2000年3月,英国国务大臣签发了新的规定,强调了医疗照射重要性和危险性。 我们的调查内容主要是医生对病人在常用的放射学检查时接受的医疗照射剂量的了解程度。 Preface Although the medical exposure is small, it is indeed harmful to the health of patients, so the relevant research has become an important part of medical practice. An estimated 100-250 deaths from cancer in the UK are directly related to medical exposure. In March 2000, the British Secretary of State issued new regulations emphasizing the importance and dangers of medical exposure. Our survey mainly focuses on how well a doctor knows about the amount of medical exposure received by a patient during routine radiological examinations.
