现代放射疗法的新技术是应用合成放射性同位素铱~(192)和采用无放射性的沟导向器。铱为一种半衰期74天的同位素,放置期间可产生相当恒定的放射剂量。分二种类型,一种为直径0.5毫米的单排或双排铱针,另一种为直径0.3毫米的铱丝。铱针疗法适用于很多皮肤病。具有疗效快的特点。为了给予6000拉得(rad)的剂量,接触放疗需要二周,电子加速器疗法约需6周,而铱针治疗仅需3或4天。
The new technology of modern radiation therapy is the application of synthetic radioisotope 铱 ~ (192) and the use of non-radioactive channel guide. Radon is an isotope with a half-life of 74 days, and a fairly constant radiation dose can be generated during placement. There are two types, one is a single row or double row of needles with a diameter of 0.5 mm, and the other is a 0.3 mm diameter wire. Acupuncture therapy is suitable for many skin conditions. Has a fast effect. In order to give a dose of 6,000 rads, radiation therapy takes two weeks, electron accelerator therapy takes about six weeks, and acetabular needle therapy only takes three or four days.
