Description/Abstract:
THIS ARTICLE EXAMINES THE USAGE OF RADIOGOLD SEEDS FOR CANCER THERAPY. RADIOGOLD SEEDS ARE CONVENIENT REPLACEMENTS FOR RADON SEEDS. THEY MAY ALSO BE USED ADVANTAGEOUSLY IN THE NEWER METHODS OF APPLICATION SUCH AS THE NYLON-TUBE IMPLANTATIONS. RADIOGOLD SEEDS ARE PREPARED BY ACTIVATING A FINE GOLD WIRE IN A NUCLEAR REACTOR AND THEN ENCASING IT IN AN INERT OUTER GOLD TUBE IN ORDER TO FILTER OUT THE BETA PARTICLES. THE 198AU SEEDS ARE CUT WITH A SPECIAL CUTTER TO ANY DESIRED STRENGTHS REGISTERED ON A RADIATION METER AS THE ENCASED RADIOACTIVE GOLD WIRE IS EXTRUDED FROM A LEAD STORAGE SHIELD. THE METER IS CALIBRATED TO GIVE THE NUMBER OF GAMMA ROENTGENS-TOTAL-AT-ONE-CENTIMETER (RTCM), WHICH THE SEED TO BE CUT WILL EMIT DURING COMPLETE DECAY. THE REACTIONS OBSERVED CLINICALLY IN 51 APPLICATIONS IN THE FIRST 46 PATIENTS IN WHICH THE 198AU SEEDS WERE USED APPEARED TO BE SIMILAR ESSENTIALLY TO THOSE OBTAINED WITH IMPLANTATIONS OF RADON, RADIUM, OR 60CO.
