ENVIRONMENTAL ASSESSMENT ELEMENTS OF URBAN INFRASTRUCTURE OF RADIO AND FACTOR OF ELECTROMAGNETIC RADIATION ^{[№ 10 ' 2015]}
In article questions of increase in sources of electromagnetic radiation of the technogenic nature, and also their dangerous influences on health of the person and a condition of natural ecosystems are considered, the main sources of electromagnetic radiations in habitat of the modern person are characterized. The choice of object of research as source of technogenic electromagnetic radiation — object of radio television infrastructure — the Orenburg regional radio television transmitting center locates, the description of the device by means of which measurements were performed is made, the measurement technique is given in compliance by methodical indications of determination of level of the electromagnetic field created by the radiating technical means of television and broadcasting the choice of the measured size — intensity of electric field according to sanitary hygienic requirements to placement and operation of the transferring radio engineering objects is reasoned, data of limit admissible level of electromagnetic radiation of the normalized size for radio television object are provided. The processed results of intensity of electric field during research in the territory of the housing estate adjacent to object of research, on border of its sanitary protection zone and far from a source of technogenic electromagnetic radiation are shown. The sequence of map development in ArcGIS 10.3 geographic information system is described. Final maps by results of all measurements with ranging of ranges of intensity of electric field are shown, the maximum and minimum values of the studied size are explained, the zone of the maximum stable excess of maximum-permissible level throughout all measurements is revealed. Conclusions are drawn on dependence of intensity of electric field on removal on object of research. Influence of a source of technogenic electromagnetic radiation and object of city radio television infrastructure — the Orenburg regional radio television transmitting center — on the adjacent inhabited territory is estimated.

ENVIRONMENTAL ASSESSMENT TRANSPORT INFRASTRUCTURE IN FACTOR NOISE POLLUTION ON THE EXAMPLE OF ORENBURG ^{[№ 10 ' 2015]}
In article features of noise as physical factor of environmental pollution, namely, atmospheric air are considered. Its influence on mental and physical health and efficiency of the person is described. In article it is allocated as the main source of noise for research — a transport stream as makes more than a half of all noise pollution and is available to carrying out measurements. For measurements of noise level the choice of the territory of the central region of the city of Orenburg — the most crowded part of the city with a set of places for a recreation and a dense transport network is reasonable. The purpose of work is drawing up the noise card and identification of zones with excess and observance of standards of maximum permissible noise level. For drawing up the noise card the audio-noise meter of the second class of accuracy by which 280 measurements on 23 city streets were carried out was used: along transport roads, adjacent buildings, recreation areas, the inhabited yards. The measurement technique is given in compliance by methodical indications of determination of the noise level created by a transport stream the choice of the measured size is reasoned. Data of maximum-permissible noise level of the normalized size for the studied objects are provided. The noise card is created with use of geoiformatsionny ArcGIS 10.3 system and made without a housing estate. All measured indicators are given in the card in average value during measurement of March, 2015. On a total conclusions are drawn on the general noise pollution of the central region, the reasons for the developed adverse situation in respect of noise pollution on streets with the maximum excess of admissible noise level are described. In work the lowered noise level on the weekend is also reasonable and shielding of noise along highways is considered by green plantings.
