Introduction: Mobile phone usage and consequently the number of mobile phone towers have mushroomed over the last few decades. These developments have raised concerns about the potential risks of long-term exposure to radiofrequency radiation (RFR) on human and environmental health. The present research aimed at investigating the cytogenetic effects of exposing two living systems to RFR at a frequency of 1800 MHz and a specific absorption rate of 0.27 W/ kg.

Materials and Methods: Onion (Allium cepa L.) root tips and Balb/C male mice were exposed to RFR at a frequency of 1800 MHz for 0, 0.5, 1, 2, and 4 h daily for 7 consecutive days. The percentage of micronuclei (% MN), micronucleated polychromatic erythrocytes (%MNPCE), and aberrant meristematic cells (% Abc) were estimated.

Results: It was shown that short and intermediate exposure resulted in progressive time-dependent enhancement of root growth. In contrast, the 4h-exposure conditions caused significant root growth inhibition. Exposure did not cause alterations in mitotic indices of meristematic cells. Only 4 h RFR exposure of roots induced significant increases in % Abc. Statistically significant higher values of % MN and % %MNPCE were observed in the peripheral blood of mice exposed to EMF for 4 h.

Conclusion: Data suggest that prolonged exposure to living organisms may result in negative effects including growth inhibition and induction of genetic changes.
