2 Biological Effects of Radiation Current knowledge about the biological effects of radiation is based on many sources, including extensive research with animals. Much of the most pertinent data for radiation protection, however, has been obtained from epidemiological studies of human populations exposed inadvertently. Early workers with X-rays and radium, both for medical and commercial applications, were exposed to radiation doses much larger than are permitted today. Patients were also treated with radiation for a variety of illnesses before the possible delayed effects were fully appreciated.
Therefore, the gaseous effluents released by the stack and the plant’s dozen secondary outlets are monitored continuously. 3 Kyshtym On September 29, 1957, a chemical explosion took place at Kyshtym in a storage tank containing 250 m3 of high-level radioactive waste, generated as a result of plutonium production operations . The explosion has been attributed to the ignition of an acetate-nitrate concentrate following the failure of a crude cooling system. 4 × 1017 Bq of activity to the atmosphere.
5% in living plants and 5% to 10% in the mineralized portion of the soil . Radiation Dosimetry: Background and Principles 43 As a result of the release, all pine trees within 20 km2 in which the dose to needles exceeded 30–40 Gy perished by late 1959. The loss of farm animals exhibiting acute radiation sickness symptoms was reported to have begun within 9–12 days in sites nearest the accident. With regard to the aquatic environment, half periods for the elimination of radionuclides from lake water varied from 1 to 24 days for 144Ce, and from 780 to 1,100 days for 90Sr.
