大家都知道,天然放射性輻射体早就应用到医学上了;很多年以来,鐳被广泛地用来治疗人体上的惡性腫瘤;在原子核分裂方面的最新科学成就,和各种化学元素的人工放射性的發現,使得把放射性物質更广泛地应用在临床实踐中成为可能。目前,在治疗和診断工作中都在应用着人工放射性同位素。放射性同位素的特性,是它們的放射β粒子和γ量子的能力。放射性同位素在医疗上的应用,是根据这一点:射棧穿透活的细胞,抑制它們的活动,并以一定綫量来破坏它們。用放射性鈷来治疗癌腫和許多其他疾病,是靠γ射綫对細胞的破坏作用。在苏联和平利用原子能科学技术展覽会上,广泛展出了在医疗上应用放
As we all know, natural radioactive radiators have long been used in medicine; for many years, radium has been widely used to treat malignant tumors on the human body; the latest scientific achievements in nuclear division, and the artificial radioactivity of various chemical elements. The discovery made it possible to use radioactive materials more widely in clinical practice. Currently, artificial radioisotopes are used in both treatment and diagnostic work. The characteristics of radioactive isotopes are their ability to emit beta particles and gamma quanta. The medical application of radioactive isotopes is based on this point: Shooting shots penetrate living cells, inhibit their activity, and destroy them with a certain amount of line. The use of radioactive cobalt to treat cancer and many other diseases is the destructive effect of gamma rays on cells. At the Soviet Union’s Peaceful Use of Atomic Energy Science and Technology Exhibition, a wide range of medical applications
