The present study consists of two experiments. The first experiment investigates the influence of chronic exposure of 428MHz radio frequency (RF) with an incident power density of 4mW/cm² on the development of chick embryos. Prolonged incubation was found in exposured eggs as compared to the non-exposured (22 vs 21 days). The average thymus weight in both sexes was smaller than that of the control. RF exposure also led to a significant decrease in the thymic cell density of female chicks. The second experiment was conducted in order to reveal the effects of chronic exposure of the immune system of mice exposed to 428MHz-RF with an incident power density of 1mW/cm² during pregnancy. It was found that RF exposure alters the immune system of mice. RF suppressed the cell-mediated immune-competence by local delayed hypersensitivity. These results suggest that chronic exposure of 428MHz-RF radiation induce biological effects on chick embryo and mice.

Good Agreement

A relationship between the power density incident on a material and the resulting cut speed is developed in terms of the thermal properties of the material. The expression obtained is general and is shown to be in good agreement with experimental results. It is shown that the efficiency of energy utilization is influenced by the incident power density and the jet diameter. The theory indicates that to maximize cut speed and energy utilization the jet diameter should be as small as possible consistent with an attainable power density.
