Abstract/Summary:
The man-made artificial background of electromagnetic fields and radiations (EMFARs) has become a common constituent of civilized society. People living near the sources of EMFARs are exposed to radiation level higher than other people. These different living conditions may produce adverse results. Some epidemiological studies have suggested that a link may exist between exposure to non-ionizing electromagnetic radiation (NEMR) and certain types of cancer. Other studies conducted by the researchers in the contra side have found no such link.; The experimental studies of this work were done using a microwave cavity spectrometer, Escherichia coli (E-coli) bacteria, and other peripheral equipment. The experiment consists of two steps. First, a general survey of frequencies from 8 GHz to 12 GHz was made. Second, a detailed experiment for specific frequencies selected from the first survey were further studied. Interesting frequency dependent results, such as unusually higher growing or killing rates of E-coli at some frequencies, were found. It is also concluded that some results are genetic, that is, the 2nd, and 3rd subcultures showed the same growing status as the 1st cultures.; Several factors may affect the biomechanisms of E-coli. Some of these are pH and salinity of the environment, the presence of other bacteria in competition with it, temperature, predatory process, the presence of sunlight, and possibly irradiated electromagnetic radiation and field. However, throughout this experimental study only the frequencies of the electromagnetic radiation were changed and all other factors were kept constant. This work was concentrated on the biological effects of NEMR.
