چکیده

introduction : the  rapid development  of wireless telecommunication technologies  over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore, the last decade witnessed  a rapidly growing concern about the possible health effects of exposure to electromagnetic fields emitted by these sources. materials and methods : in this study that was aimed at investigating the effects of exposure to radiofrequency (rf) radiation emitted by a gsm mobile phone on the pattern of contraction in frog’s isolated gastrocnemius muscle after stimulation with single square pulses of 1v (1 hz), pulse height of contractions, the time interval between two subsequent contractions and the latency period were measured. results : our findings showed that the pulse height of contractions muscle could be affected by the exposure to electromagnetic fields. especially, the latency period was effectively altered in rf-exposed samples. however, none of the experiments could show an alteration in the time interval between two subsequent contractions after exposure to electromagnetic fields. conclusion : these findings support early reports which indicated a wide variety of non-thermal effects of electromagnetic radiation on amphibians including the effects on the pattern of muscle extractions.

Induction of apoptosis by 900 MHz radiofrequency radiation emitted from a GSM mobile phone simulator in bystander Jurkat cells

Background: Radiation-induced bystander effect is a response which results in damage in non-irradiated cells in response to signals from the irradiated cells. The aim of the present study was to investigate microwave-induced bystander effect from a GSM mobile phone simulator on induction of apoptosis in Jurkat cell line. Materials and Methods: Jurkat cells were divided into three groups of non-...
