- W204574883 abstract "In less than ten years teletherapy has progressed from the idea stage to successful commercial exploitation . About 350 sources from the United States and Canadian producers alone are now being used to treat patients, and this is only cobalt-60. This same rapid Cesium- 137 sources now are in the developmental stage. Preliminary work has shown that its long half life gives economic advantages; its half-million electron volt radiation does not cause great differences in clinical use but reduces the problem of radiation protection considerable. A third source material, strontium-90, is in the early stage of development. Many other radioisotopes have been used but have some practical disadous problem still remains: finding a practical and economical radioisotope in the quarter-million electronb volt range. The clinical program and with teletherapy has been outstanding. ng, decreased bone absorption, and increased depth dose." @default.
