The data on the biological effectiveness of radiation in small doses are of major importance in substantiating the maximum permissible doses. It is generally believed that the mechanism of transmission of hereditary traits is most sensitive to ionizing radiation. Any other biological system in which the restoration processes are insufficiently pronounced may, however, be sensitive to the same extent. Developing organs and systems are especially sensitive. The intermediate action of radiation on the organism through the central nervous system may be considered as an important physiological factor which accounts for the high sensitivity of animals to irradiation. Special methods were employed to demonstrate the high sensitivity of the nervous system to the action of ionizing radiation. Considerations are advanced suggesting absence or limited range of adaptation mechanisms in relation to ionizing radiation. Data are presented on the summation phenomena revealed in the process of maligant neoplasms induced by prolonged exposure to incorporated longlived fission products in small doses. The material presented calls for a revision of the views held on the biological effectiveness of ionizing radiation in small doses. (auth)
