| 当X射线照射到生物机体时，生物细胞受到抑制、破坏甚至坏死，致使机体发生不同程度的生理、病理和生化等方面的改变，称为X射线的生物效应。不同的生物细胞，对X射线有不同的敏感度。枫X射线可以治疗人体的某些疾病，如肿瘤等。另一方面，它对正常机体也有伤害，因此要做好对人体的防护。X射线的生物效应归根结底是由X射线的电离作用造成的。 由于X射线具有如上种种效应!因而在工业、农业、科学研究等领域，获得了广泛 的应用，如工业探伤，晶体分析等。在医学上，X射线技术已成为对疾病进行诊断和治疗的专门学科，在医疗卫生事业中占有重要地位。 When X-ray irradiates biological organisms, biological cells are inhibited, destroyed or even necrotized, resulting in physiological, pathological and biochemical changes in varying degrees, known as the biological effects of X-ray. Different biological cells have different sensitivity to X-ray. Maple X-ray can beijing.89ix.com zhixiang.07858.netdianxiangan.37ix.cn zhoucheng.37ix.cn chongdianzhuang.07858.net langyashan.37ix.com.cntreat some diseases of human body, such as tumors. On the other hand, it also harms the normal body, so we should do a good job of human protection. The biological effects of X-rays are ultimately caused by the ionization of X-rays. X-ray has been widely used in industry, agriculture, scientific research and other fields, such as industrial flaw detection, crystal analysis and so on. In medicine, X-ray technology has become a special subject for the diagnosis and treatment of diseases, and occupies an important position in the medical and health undertakings. |
