价值3百万英镑,具有最强穿透性能并能精确地发出中子辐射射束的6亿电子伏回旋加速器最近在英格兰西北部利物浦附近的Clatterbridge医院安装完毕。并在84年年底开始作治疗病人试验。这种装置是利用原子核中的粒子,即中子治疗肿瘤的。当回旋加速器产生高能射束时,中子穿透人体组织,能成功地攻击那些X射线,α射线无能为力的肿瘤细胞。利用中子治疗肿瘤开始于伦敦的Hammersmith医院,虽然该院的回旋加速器只有7千万电子伏,但产生的好成绩给人以深刻的印象:治疗面部和颈部的晚期肿瘤成功率可达76％,而通常用的X射线治疗率只达40％;对于接近体表,无明
The 600 million electron cyclotron, worth £ 3 million and the most penetrating and capable of accurately emitting a neutron radiation beam, was recently installed at Clatterbridge Hospital near Liverpool in northwestern England. At the end of 84, treatment trials began. This device is the use of nuclei in the particles, that neutrons treatment of tumors. When the cyclotron produces a high-energy beam, neutrons penetrate human tissues and successfully attack those X-rays and alpha rays that are powerless. The treatment of neoplasms with neutrons began at Hammersmith Hospital in London, and although the hospital's cyclotron had only 70 million electron volts, the good results were impressive: the success rate of advanced tumors in treating the face and neck was 76 %, While the commonly used X-ray treatment rate of only 40%; for close to the body surface, ignorance
