Does all-day and long-term exposure to radiofrequency radiation emitted from Wi-Fi affect hearing?
Biotechnology & Biotechnological Equipment, 2017 We investigated the long-term effects of radiofrequency radiation (RFR) emitted from Wi-Fi systems on hearing. Sixteen Wistar albino rats were divided equally into two groups: sham control and exposure groups.
