“…No firmly constructed or widely accepted theory of the mechanism of non‐thermal effects exists, nor is it understood whether any of the effects reported are harmful or helpful, or simply fall within the range of the normal variation of biological parameters. Epidemiological studies have not produced definite evidence of harmful effects 3,4. In 1986 an advisory committee to the National Academy of Sciences National Research Council of the United States reported on the results of the large body of work in this field.…”

“…Epidemiological studies have not produced definite evidence of harmful effects. 3,4 In 1986 an advisory committee to the National Academy of Sciences National Research Council of the United States reported on the results of the large body of work in this field. The committee concluded that the available evidence was still inconclusive and that judgment must be reserved on the question of health hazards arising from the non-thermal effects of long duration microwave exposure.…”

A microwave tissue coagulator originally developed to control hemorrhage during hepatic resection has recently found widespread use in the field of minimally invasive surgery. This surgical tool is based on the principle that by radiating a 2450-MHz (12-cm wavelength) microwave from a monopolar antenna within tissue, the heat generated will be limited to within the electromagnetic field generated around the antenna, leading to coagulation of protein in that field. It is therefore possible to use this monopolar antenna as a surgical electrode. The coagulation field is determined by the relationship between the wavelength frequency, tissue-specific permittivity, antenna length, waveform and output, and duration of the irradiation. Since this technique has been applied to devise a new method of hepatectomy, it has also found use in various other surgical fields, such as gastrointestinal tract endoscopic surgery, laparoscopic surgery, and percutaneous surgery. It has also enhanced therapeutic results, notably in cancer therapy.

“…These authors (67) have attributed their findings to subthermal or nonthermal interactions between the energy and the biological system. Much of the work has been criticized by those who feel that the systems were subjected to a thermal stress, and these experiments have not yet been independently replicated (68). It is quite possible that the chosen parameters of the ,applied field caused biologically significant field-induced force effects (7).…”

During the last 25 years, there has been a remarkable development and increase in the number of processes and devices that utilize or emit microwaves. Such devices are used in all sectors of our society for military, industrial, telecommunications, and consumer applications. Although there is information on biologic effects and potential hazard to man from exposure to microwaves, considerable confusion and misinformation has permeated not only the public press but also some scientific and technical publications. The purpose of this review is to place the available information on biologic effects of microwaves in proper perspective and to suggest approaches to future studies.

Turkey sperm were exposed to 2.45 GHz microwave radiation in a temperature controlled waveguide apparatus. Temperature was maintained at 40.0 +/- 0.5 degrees C. The sperm were exposed for 30 min to a specific absorption rate (SAR) of 1, 10, or 50 mW/g. Before and following microwave exposure the following parameters were examined: percentage viability, percentage abnormal sperm, and release of the enzymes lactate hydrogenase (LDH) and glutamic oxalic transaminase (GOT). These parameters were not altered significantly by microwave exposure under the conditions tested.
