An aim hired consisted in the scientific ground of hygienical requirements to placing and ex-ploitation of cable busses (ÊË) of electricity transmission in the conditions of modern municipal building.
Methods of researches: calculation, instrumental, mathematical, toxicological, physiological, biochemical, haematological.
Sanitary-hygenic description of terms of placing and exploitation of high-voltage ÊË of elec-tricity transmission is first given by tension 110-330 ê and to their electric substations 330/35/10 êÂ; the set pri ority factors of influence on an environment are the electric and magnetic field (MT), acoustic contamination, and at emergency situations extrass of chemicals of ýëåãàçîâîãî equipment (hexafluoride of sulphur); conformities to law of spatial distribution are set in the environment of the enumerated factors; worked out criteria of their hygienical estimation; the set conformities to law of violations of exchange processes and ïîâåäåí÷åñêèõ reactions are in the organism of experimental animals at loading MT at the level of 30 and 90 ìêÒë; the hygienical norms of MT are worked out 50 Hertzs for territories of the different functional setting (housing apartments, municipal building, out of housing building, difficult of access locality); the safe level of act (ÎÁÐÄ) is set approximately hex-afluoride of sulphur for air of the inhabited places within the limits of concentrations 37±7; hygienical requirements are scientifically reasonable to placing and exploitation of high-voltage ÊË of electricity transmission, and also to their equipment in the conditions of making more compact municipal building.
