X 射线对人体造成损害是长期累积性的,早期往往缺乏任何明显症状,易被人忽视,但工作人员如能严格掌握防护措施,X线应用是绝对安全的,不会产生机体的损害。平时 X 线诊断检查对病员的累积剂量极小,对健康毫无影响,据统计医用 X 线对人体(系指性腺与骨髓)的平均累积量30年为8伦(70年为15伦),这个剂量仅相当于同等时间内人体所接受的“自然本底辐射量”(本底辐射量包括宇宙线,大气中放射物质,以及自然界的体内照射 C~(14),K~(40),其总剂量
X-rays cause long-term accumulation of damage to the human body. In the early stages, they often lack any obvious symptoms and are easily overlooked. However, if the staff can strictly grasp the protective measures, X-ray applications are absolutely safe and will not cause damage to the body. The normal X-ray diagnostic examination of the patient’s cumulative dose is minimal, no effect on health, according to statistics, the medical X-ray on the human body (referring to the gonads and bone marrow) the average cumulative amount of 30 years for 8 years (70 years for 15), This dose corresponds to the “natural background radiation” accepted by the human body within the same period of time (background radiation includes cosmic rays, radioactive substances in the atmosphere, and natural body radiation C~(14), K~(40), The total dose
