The biologic effects of radiation on normal tissues and tumors represent a complex area for investigation. These effects are of far-reaching consequence to the diagnostic radiologist and the radiation oncologist having a significant impact not only in concepts relative to radiation protection but also in concepts relative to tumor biology and its response to radiation injury. The volume edited by SCHERER, STREFFER, and TROTT represents an extension of basic radiation biology data into the effects of radiation in producing pathology in organs and tissues. The data presented by the multiple...

The aim of radiation protection standards is to make the radiation workplace as safe as is humanly possible. The gradual evolution over the last 20 years has been towards a more precise definition of the limits for occupational exposure. These have been created not only in terms of short-term effects but also more importantly in terms of long-term risks involving such problems as the potential for carcinogenesis and genetic change. In the United States the National Committee for Radiation Protection has recom mended that 5 rems (50 mSv) should remain as the maximum permissible dose equiva...

Non-malignant, or "benign," diseases can be successfully treated using ionizing rad- tion technologies. It was first proposed in 1898 by Sokoloff, who reported the analgesic effects of radiotherapy for painful rheumatoid arthritis. Since then, the use of these techniques for painful muscle-skeletal diseases has gained acceptance particularly in Europe but is still carried out actively in the United States. Non-malignant diseases that are amenable to radiotherapy can be classified as inflammatory, degenerative, hype- roliferative, functional, or other disorders. However, the topographic and...
