Abstract : An international and wide dispute is currently undergoing about the radiation emitted from the electric current of high voltage, domestic connections or appliances; and about their effects on human beings either directly or indirectly. People are divided about their risks between an exaggerating group and a group that paid no attention to them. Researchers also show a discrepancy, according to their results As a result, legislation committees and organizations varied in defining the exposure limits of electric and magnetic fields of 50/ 60 Hz. This research puts forward an introduction to the extent of this dispute compared to other types of radiation of electromagnetic spectrum. It also clarified the variation of other research works, exposure limits and causes. This study comes out with the followings: First: Exposure to electric and magnetic fields within the permissible limits issued by international committees, such as (ICNIRP) and others. There has been no definite evidence that exposure to these fields is linked to diseases such as cancer in children or adults. In one hand, the scientific and statistic researches that presented this link were short of controlling factors that interfere in the occurrence of these diseases, or they were not supported by researches confirming this link. On the other hand, there are many researches that disapprove such link between those fields and cancer. The main verification that can be used by those who approve such link is the classification of the very low frequency electromagnetic radiation as a carcinogen issued by IARC. Second: specialized organizations open the door for researches in this field because the idea of a link between exposure to electric field and cancer still exists. Third: Technical faults, which increase radiation pollution, should be avoided by putting rules for the methods w «d « t?K «b bL ?¥ of electrical connections. Forth: Exposure rates below limits of the electromagnetic emissions, due to high power and other electric network, should be further reduced if possible economically since there is no confirmed link between such rate limits and health. However, technical faults are not accepted, i.e., they should be fixed even exposure rates are very low.
