R RADIATION ECOLOGY Radiation Ecology or Radioecology is a term that came into common usage in 1956 to denote that area of the broad field of ecology concerned with the assessment of radioactivity in the environment. More specifically, radiation ecology has come to be recognized as that area of ecology concerned with radioactive substances, radiation and the environment. The development and subsequent expansion of nuclear energy for military and peaceful purposes has been accompanied by environmental problems, some of which are typical of other facets of industrialization and some unique to atomic energy. The unique problems primarily concern the fate and ecological. | R RADIATION ECOLOGY Radiation Ecology or Radioecology is a term that came into common usage in 1956 to denote that area of the broad field of ecology concerned with the assessment of radioactivity in the environment. More specifically radiation ecology has come to be recognized as that area of ecology concerned with radioactive substances radiation and the environment. The development and subsequent expansion of nuclear energy for military and peaceful purposes has been accompanied by environmental problems some of which are typical of other facets of industrialization and some unique to atomic energy. The unique problems primarily concern the fate and ecological effects of radionuclides released into the environment. The major environmental problems introduced by the Atomic Age may be grouped into several areas of scientific and public concern. Underlying each of these is the worry about the effects of ionizing radiation on man his domesticated plants and animals and on the environment and its living components Fallout from weapons testing reactor radioactive waste effluents radioactive waste disposal nuclear war and use of nuclear explosives for major engineering and related technological projects of large scale comprise the activities which have concerned society and which because of potential impact on the environment and man have stimulated the development of radiation ecology. Understanding the manner in which our ecological systems ecosystems distribute assimilate and affect the environmental behavior of radioactive substances and the effects of radiations emitted from those substances are the concern of the radioecologist. RADIONUCLIDES OF ECOLOGICAL IMPORTANCE Radionuclides which are of interest to the ecologist are listed in Table 1. These radioactive elements represent the major naturally-occurring and man-made sources of radiation in the environment. Principal sources of exposure from background natural radiation are represented by the uranium thorium .
