High dose rate, remote-afterloading intracavitary irradiation (RALS) and low dose rate, interstitial irradiation were discussed. In Japan, RALS is now a standard treatment for uterine cervix carcinoma. In interstitial radiotherapy, radium sources, because of their poor conditions of protection and excessively long half-life, are being replaced by several new radioactive elements, such as 60Co, 125I, 125Cs and 192Ir. These have suitable characteristics for afterloading and safety protection. Among them 192Ir has become common source, not only for intraoral cancer, but also various other tumors including rectal, breast, and bile duct cancers.
讨论了高剂量率后装腔内照射（RALS）和低剂量率组织间照射。在日本，RALS目前是子宫颈癌的标准治疗方法。在组织间放射治疗中，镭源由于其防护条件差和半衰期过长，正被几种新的放射性元素所取代，如60Co、125I、125Cs和192Ir。这些元素具有适合后装和安全防护的特性。其中192Ir已成为常用源，不仅用于口腔癌，还用于包括直肠癌、乳腺癌和胆管癌在内的各种其他肿瘤。
