放射线被普遍用于医疗诊断中,在应用的过程中,应该防止其对人体带来的危害。本文为了总结放射线对人体的影响和防护对策,首先分析了放射线对人体的影响、产生害处的生理基础和限制剂量,认为采用屏蔽保护、距离保护、时间防护、污染控制、定期检查设备、定期体检和饮食防护,可以在一定程度上减轻放射线对人体的损害。 Radiation is widely used in medical diagnosis, in the application process, should be to prevent its harm to the human body. In order to summarize the influence of radiation on the human body and the protective measures, the paper first analyzes the influence of radiation on the human body, produces the physiological basis of harm and restricts the dose. It considers shielding, distance protection, time protection, pollution control, periodic inspection equipment, regular physical examination And diet protection, to a certain extent, reduce radiation damage to the human body.
