医用X射线机发射的X射线对人体的作用是来自体外照射。辐射防护方案的设计目标是保证医疗质量和医疗安全，以确保放射诊疗工作人员、患者和公众的健康权益。辐射防护与辐射安全设计依据国家的法律、法规和国家标准，为减少X射线对人体照射影H向9在进行屏蔽防护计算时，应考虑X射线装置的管电压、管电流、投照时间、参考点离源距离、剂量限值等因素，一般可采取增大与放射源的距离、缩短受照时间、采取用防护材料加以屏蔽等办法，即遵循放射实践正当化、辐射防护最优化以及个人限值的辐射防护基本原则。同时，医用诊断X射线机机房的设置必须充分考虑临室及周围场所的防护与安全，一般可设在建筑物底层的一端，且机房应有足够的使用面积。

The effect of X-ray on human body primarily caused by external irradiation from medical X-ray machine. The main aim of the radiation protection design is provide ensaring medical quality and safety of medicl care, pvotecting the Health Rights and Interests of radation workers,patients and public. The design according to national regulations and standards should obey the basic principle of radiation protection. That demands optimizing many factors including the tube-voltage and tube-current of the machine, the time and doses of exposure and the distance from the measuring point to the radiation source. In addition, the design of the machine room must pay attention to the effect to the environment. Forexample, the location of the machine room usually set on one end at the first floor with enough utilization area.
