Zabolotny Institute of Microbiology and Virology of the National Academy of Sciences of Ukraine Microorganisms as a model system for studying the biological effects of electromagnetic non-ionizing radiation • Elena N. Gromozova • Voychuk S.I., Zelena L.B., Gretckey I.A.
IMV NASU is the biggest scientific research center in the area of systematic, physiology, biochemistry, ecology and genetics of microorganisms, biotechnology and general virology in Ukraine and one of the biggest research centers in the former USSR. Organized on the 31st of May 1928 by the Dmitriy K. Zabolotny. Directions of work Study of fundamentals of biologic activity of microorganisms and viruses aimed at its regulation Study in ecology and systematic of microorganisms and viruses, strain selection and development for the biotechnological needs The Ukrainian Collection of Microorganisms • the big collection of nonpathogeneous strains of microorganisms a lot of which are used in molecular-biological investigations and biotechnology
Objects of research Saccharomycescerevisiae Schizosaccharomycespombe Candida spp. Chromosomal aberrations in cells of onion (Allium-test)
Two directions of our researches Natural radiation Anthropogenic EMF
Metachromazy reaction Volutin grains “Dancing bodies” Volutin grains morphology (PO4)n
Anthropogenic EMF VHF (very high frequency) EMF generators UHF (ultra high frequency) EMF generators 40.68 MHz, 15W, 30W, DCS-1800MHz 10-1000 mkW/cm2 EF = 90-92 V/m, MF = 1.25-2.2 А/m Used in globalsystemformobilecommunications Used in medicine for UHF-therapy EHF (extremely high frequency) EMF generator Video display terminals (VDT) 30-40GHz, 25mkT Used in medicine for EHF-therapy Emit complex radiation of varied frequencies
