Behavioral characteristics of SD rats exposed to power frequency magnetic field

How to determine the effects of electromagnetic phenomena in the environment on human health is one of the main concerns of scholars. The biological effects of electromagnetic fields are related to the characteristics of electromagnetic fields and the electromagnetic properties of biological tissues. The main purposes of this paper are as follows: on the one hand, to explore the statistical laws of animal behavior of Sprague Dawley (SD) rats in magnetic field exposure devices, and strive to pass them. Statistical data confirm the consistency of animal behavior in SD rats with and without magnetic field exposure. On the other hand, the rationality of the current mainstream magnetic field limit is demonstrated from the side. Based on the self-developed magnetic field exposure device, the animal behavior of SD rats was studied by open-field experiment, elevated cross maze experiment and water maze experiment. The control group (0 μT exposure) and exposure group (30μT exposure, 100μT exposure,500 μ T exposure) in the very low frequency electromagnetic field exposure device were analyzed by SPSS statistical analysis software. While ensuring the integrity of the experimental steps, the statistical rules of animal behavior of SD rats under magnetic field exposure of 30μT, 100μT and 500μT were consistent with those at 0μT. The results showed that 30μT, 100μT and 500μT magnetic field exposure did not affect rats. In order to produce the conclusion of direct interference and direct influence, the rationality of the current mainstream magnetic field limit is proved.
