The impact of static electric fields (SEF) on mice blood parameters is studied under normal temperature and pressure conditions and in the same location. The experiments were carried out using two static electrical field strengths of 67 kV/m and 133 kV/m, respectively. Experimental 35 mice have been subdivided into seven groups: a control group (T1), and three groups (T2, T3, and T3) that were exposed to 67 kV/m for three periods of 0.5 h , 1 h, and 1.5 h daily for 21 days, respectively. The other three groups (T4, T5, and T6) were exposed to 133 kV/m for the same periods of 0.5 h, 1 h, and 1.5 h daily for 21 days, respectively. The results indicate that there is a highly significant mean difference in blood parameters that are; white blood cells (WBC), red blood cells (RBC), and platelets (PLT) using an intensity of 133 kV/m rather than using an intensity of 67 kV/m. moreover, mice that exposed to 133 kV/m suffer aggressive behaviors and baldness. Indead, the results indicate that there is a significant difference (p < 0.05) when using animals exposed to 133 kV/m for 1.5 h, this means that increasing SEF strength and exposure time might affect not only on blood parameters but also on the animal behaviors.
