Ecological Systems and Devices Annotation << Back On the development of criteria for radiation hazard Zaytsev V.V. Buchnev A.A. Ivliev M.V. Paramonovа T.I. On the map of modern Moscow can be identified both linear and circular tectonic structures. Of special highlight extending from the northwest to the southeast lineament zone. Changes along linear tectonic structure and composition of the upper clastic sediments - sand, loam, clay, etc., that together with technological soils affects the radiation component. In the paper, a method of ranking in Moscow on radiation hazards on the basis of the estimated coefficients of relative total radionuclide activity of soils and sediments. Keywords: linear tectonic structures; radionuclides; the activity of radionuclides; the ranking territories radiation hazards. Contacts: E-mail: mosconfere@rambler.ru Pp. 14-17.
