Description/Abstract:
THE PURPOSE OF THIS ARTICLE IS TO DISCUSS APPLICATIONS OF ADVANCES IN NUCLEAR PHYSICS IN THE RESEARCH OF CANCER. THE MOST IMPORTANT TECHNICAL DEVELOPMENT IS THE CHAIN-REACTING "PILE." THIS PROVIDES A METHOD OF PREPARATION OF VERY LARGE AMOUNTS OF RADIO-ACTIVE ISOTOPES. THE CYCLOTRON STILL REMAINS AN ESSENTIAL INSTRUMENT BOTH FOR THE PRODUCTION OF SMALL AMOUNTS OF CERTAIN ISOTOPES AND AS A SOURCE OF FAST NEUTRONS FOR THERAPEUTIC TRIAL IN CANCER AND RELATED DISEASES. FROM THESE PRODUCTIONS, THE MOST PROMISING SUBSTITUTE FOR RADIUM IS CONSIDERED TO BE RADIO-COBALT, 60-CO, WITH A HALF-LIFE 5.3 YEARS. THE SECOND CHOICE IS PROBABLY 182-TA, WITH A HALF-LIFE 97 DAYS. THE GAMMA RADIATION FROM RADIO-COBALT APPEARS TO BE EMINENTLY SUITABLE FOR RADIO-THERAPEUTIC APPLICATION.
