射线原与宇宙同存。直到上世纪末国际上物理学界对阴极线的研究中,伦琴发现了“X线”——不知何名的光线。自此掀起研究放射线的热潮。当其中一些人受到照射后出现机体组织损伤现象,临床医学家也涉进这领域。随后发展成为一个专门科学,称放射肿瘤学。 The ray and the universe exist together. Until the end of last century, international studies on the cathode line in the field of physics, Roentgen discovered the “X-ray” - unknown light. Since then, the upsurge of studying radiation has been set off. When some of them have been exposed to radiation, body tissue damage has occurred and clinical scientists have also been involved in this area. Then it developed into a specialized science called radiation oncology.
