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.
