Our atmosphere is full of electromagnetic fields emitted from wireless communication transmitters. At the same time the bio-systems (including humans, animals & birds and vegetation as well) are complex electrical systems. Naturally therefore, they are likely to have interaction and to be affected in some way or the other. Research into this field started with the knowledge about pleasing presence of negative charges and unpleasant presence of positive charges around us, concentrating effects of static or pulsating fields. Also came the explanation (and experimental verification) of Hindu mythological effects of geomagnetic fields coupled with solar activity. The effects of power line radiation and radiation from video game TV sets, microwave oven and other domestic instruments like electric blankets also figured in the research. At last the fastest emerging mobile telephony overpowered all others. Though the results of researches into possible harmful effects of mobile phone radiation and those of radiation from base station towers remain inconclusive partly because of influencing pressure from manufacturing and service providing companies, some of the researchers conclusively assert the harmfulness of the radiation at some level of field intensity present near the tower or the handset relating it to the specific absorption ratio (SAR) value. Recent increased observation of infertility among young couples is also attributed by some researchers to the effect of radiation from mobile kept in pantaloons pockets which becomes near their genitals affecting sperm or ovum. This review explains all these researches into bio-effects of electromagnetic fields and concludes that there is certainly some possible harmfulness of radiation above some level of intensity of fields.
