| Summary: | To The Editor: Exposure to electromagnetic radiation (EMR) from mobile phones can cause detrimental effects on cell function, chromosomal aberrations, and tissue injuries [1-6]. The rapid expansion of mobile phones has lead to widespread concern for their safety. We examined the histopathological effects of direct exposure to this EMR from mobile phones in adult male Swiss albino mice. The animals were obtained from the biotechnology center, Tripoli, Libya, weighing from 25-30 grams, aged 10-12 weeks. The experiments were approved by state authorities and fol¬lowed guidelines of Egyptian law for animal protection. Mice were fed standard diets and water ad libitum. Plastic cages (diameter 45 cm by 11 cm height) were designed for this work. The roof of the cage was designed to receive the mobile phone from a distance of about 10 cm from the cage floor [7]. EMR was emitted from the Nokia 1112 device with a dimension of 104×44×17 in connection with Libyan network (Misurata, Libya). The distance between phone and mice was about 10 cm. The GSM mobile phones operate with microwave carrier frequencies in the GHz range (850–1900 MHz) [8-10].
