Effect of low-dose electromagnetic radiation on peripheral blood cells in mouse

Male Babl/c mouses were exposed to 0.625 mW/cm2 and 1.25 mW/cm2 2856 MHz microwaves for 30 min×2 times. Venous blood samples were collected at 1 h,1 d,3 d，7 d,15 d and 30 d after exposure and differential counting of blood cells were performed． Immediate increases in white blood cell count and percentage, neutrophilic granulocyte count and percentage were observed after exposure to 0.625 mW/cm2 and 1.25 mW/cm2 microwave irradiations. On days 3，7 and 15，they elevated more significantly than contro1 group （p≤0.01）．Lymphocyte count and percentage decreased after exposure to both irradiations. On days 3，7 and 15， they reduced more significantly than contro1 grop （p≤0.01）. Both 0.625 mW/cm2 and 1.25 mW/cm2 dose exposures have little effect on， platelets and erythrocytes. Low dos
