[en] Exposure pathways of natural source radiation on man are shown. Radiation earth sources give on an average more, than 5/6 of the year effective equivalent dose absorbed by population mainly due to the internal radiation. Radon and its decay products which are contained in many building materials and in water and natural gas as well, require particular attention. Necessity to carry out radiation control of building materias, as well as, other measures dealing with reduction of radon concentration in houses is underlined

[en] Certain data being in the IAEA confidential report on plutonium preservation control at NPPs are presented. It is outlined that any nuclear program can be used in two ways: either as energy-generation or millitary one when solving engineering problems

[en] Medical effects of the Chernobyl accident for various groups of people engaged in liquidation of the accident aftereffects and residents of the regions affected are assessed. Specific medical and social recommendations for each of the five groups of patients are made. Special attention is paid to the health of children who were exposed to external radiation in combination with intake of iodine isotopes. Extremely unfavourable influence of the mass media on the health of people involved in the Chernobyl accident is painted out. The necessity of adequate rehabilitation measures for various categories of patients involved in a large-scale accident is emphasized

[en] The state of nuclear power, tendencies in its development, basic (trends of IAEA activities are outlined. In 1983 all over the world 317 NPP units have been in operation and 209 units under construction. In 1985, 15% of the whole world power have been generated at NPPs. In the 1990-2000 period in industrially developed countries nuclear capacities grow 1.5 times. An important work is carried out by IAEA in the field of safeguarding non proliferation of nuclear weapon. The technical aim of safeguards consists in timely detection of nuclear materials diversion to nuclear explosives production. For collection and dissemination of information among 67 IAEA member-states the International nuclear information system (INIS) is created. The IAEA activities are directed towards both general planning and development of auxiliary structures of nuclear power and its fuel cycle. IAEA has formulated basic norms on nuclear safety and environmental control. Great assistance is rendered by IAEA to developing countriesries

[en] The technical state of the Ukrytie object, which was installed more that twelve years ago over the Chernobyl NPP accident unit, is analyzed in detail. By the estimates of specialists about 130 t of nuclear fuel is positioned under the Ukrytie object roof. The greatest danger consists in the possibility of fuel dust emission beyond the sarcophagus boundaries. It may occur due to the Ukrytie structure demolition. By the estimates of the Ukrainian engineers the probability of such a fall equals 0.1 a year. Special attention is paid to the possibility of originating self-sustaining chain reaction in the fuel-containing mass

[en] Evaluation of radiation situation around the PO MAYAK: data on radiation dosimetry and volumes of radioactive contamination in the environmental medium is given. The data on radionuclide migration in the Techa river and other water basins as well as on the flora and fauna contamination are presented

[en] The problems on developing the fuel-power complex (FPC) in Russia which provides for vital activities of other branches of the national economy of the country are discussed. The taxation policy of the State plays an important role in stabilization of the financial situation at the FPC enterprises. Special attention is paid to the improvement of the system for the FPC products price formation. The forecast of the FPC development in Russia for the period of 2005 to 2010 years is presented. The diagrams for the coal, natural gas and oil mining and electrical power production by two scenarios of the FPC development for 2000 up to 2010 years are also presented

[en] The possibilities of the solar energy application for the heat and electrical power supply of the house located in the center of Europe are considered. The optimal form of the house which provides for the minimum energy losses and maximum solar energy application is determined through the mathematical modeling. Special attention is paid to the transparent thermal insulation (TTI) considering the thin-wall capillaries (30 μm). The house wall fragment with TTI which is located on the south facade, is described in detail. The photoelectrical battery with the peak capacity of 4.2 kw is mounted on its roof for supplying the house with electrical power. The square of all compartments in the house is equal to 332 m². All the electrical equipment in the house refers to the energy-saving class

[en] Energy problems in the XXI century are discussed. Bearing in mind the current tendencies in energy consumption, the assumption is made that global energy consumption in the century will increase 4-6-fold and it will reach 35-40 bln. t.o.e. It is assumed that energy consumption will grow largely in the countries of Asia, Africa and Latin America. Natural gas, oil and coal will be the main kinds of fuel in the world energy in the first half of the XXI century. Generation of thermonuclear energy will presumably grow to commercial level by beginning of the XXI century. Special attention is paid to evaluation of energy resources in Russia and development of Russian nuclear power. Outlooks for construction of an energy bridge between Russia and the North-East Asia countries (China) are considered

[en] Uranium 235 'burns' in NPP pile. Its content in natural uranium equals only 0.71%. To garantee NPP promising character it is necessary to produce nuclear fuel, using 'noncombustible' raw material - uranium 238 and thorium 232. Their reserves are practically inexhaustible. Electronuclear breeding represents the method which doesn't require task development and doesn't use high-toxic tritium. Possibility of electronuclear breeding with the use of proton linear accelerators is shown. Possible design of units for electronuclear breeding is given. Calculations showed that beam of protons, accelerated up to 1 GeV, with 300 mA current in uranium target with 0.3% enrichment would produce 1.85 t of plutonium per year. According to economical estimations for Canadian 1 TeV linear accelerator with 300 mA proton average current the cost of one gram of plutonium-239 equals 80 dollars(up to 100 dollars - after chemical treatment)
