The radionuclide content in coal from different deposits and ash-slag wastes from coal-burning thermal power plants (TPP) as well as in atmospheric emissions together with fly ash from TPP is analyzed. The problems of using coal with high content of naturally occurring radionuclides and methods for solving them at the Urtuiskii lignite deposit in Transbaikalia are illuminated. Data on the content of naturally occurring radionuclides in Transbaikalian coal and the weighted mean content of uranium and thorium in Siberian region coal are presented. Information on the radiation conditions near coal-burning TPP, the effect on the environment and public health is presented.
1 Elemental, mineral and radionuclide composition of the Slovianska thermal power plant ash-slag has been determined. The ash-slag fractions refer to the first class of radiation safety. The quantitative oxide composition is the following: SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO and MgO. The granulometric fractions of wastes can be recommended as the components of light concretes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
