摘要:
The increasing usage of wireless comunication systems and electric-electronical systems in daily life has caused a concern over possible adverse effects of radio frequency radiation (RFR) and Extremely Low Frequency Magnetic Fields (ELF-MF) on biological systems. The aim of the study was to investigate the long-term effect of 900 MHz RFR and ELF-MF exposure on nasal mucosa and nose skin of rats. In this study two different exposure systems were used to get information about the effects of RFR emitted from mobile phones and ELF-MF on nose. In the first part of the study Twenty one Wistar Albino adult male rats (sham: 7, exposure: 14) were used to determine the effects of 900 MHz RFR on nose. For the exposure group, rat heads were exposed to the 900 MHz RFR 2 h per day (7 days in a week) for 10 months. For the sham group, same process was applied to the rats, except that the generator was turned off In the second part of the study 30 male Sprague-Dawley rats (Mona: 10, first exposure: 10, second exposure: 10) were used to determine the effects of 100 mu T and 500 mu T extremely low frequency magnetic field (ELF-MF) which complies to the safety standards for public and occupational exposure. The rats in the exposure groups of this part of the study were exposed to 100 mu T and 500 mu T ELF-MF for 2 hours per day (7 days in a week) during 10 months in a Plexiglas cage. For the sham group, the same experimental process was applied to the rats but ELF-MF generator was turned off The results of the present study showed that 10 months of exposures of mobile phones and ELF-MF do not affect the mucous membrane and skin of nose. In conclusion, radiofrequency and ELF-MF used in this study do not affect nasal skin and mucosa of rats exposed to 900 MHz RFR, 100 mu T and 500 mu T ELF-MF.
