Abstract

Background and aims: The increasing use of productive machines with electromagnetic waves of different frequency and severity has led to perform many studies about the possible impact of the waves on the health of living creatures. The aim of this study was to investigate memory function and reminding in mice, exposed to microwave radiation with a frequency of 950 MHz (GSM signal). Methods: In this experimental study, 120 male mices were divided into 10 groups of 12 animals in each group. The exposed 9 groups were under microwave radiation at the power densities of 0.02, 1.3 and 8.6 mW/ cm2 and the time intervals of 2, 4 and 6 hours and one group was considered as control. The analysis of mice’s memory was done with the passive avoidance trial test and by measuring the frequency of animals entering the dark compartment of shuttle box and their entrance latency time in 6, 12, 24, 48 h, 1 and 2 weeks after the last learning stage. Results: The results showed no significant changes among the latency time of animals in entrance to the dark side of compartment, but the frequency of entrance showed significant difference among the exposure groups with the potent of 0, 0.02, 1.3 and 8.6 mW/cm2. Conclusion: Memory function and analysis of animals exposed to mobile radiation show a decrease depending on exposure time and power. The increasing frequency of animal in entrance to the dark field with the memory of electrical shock should be a sign of animal memory impairment with the exposure to the microwave mobile radiation.
