Aim and Objectives: Mobile towers are known to emit a radiofrequency (RF) radiation continuously, which increases the health concern of living beings. However, still the biological effect of exposure to RF remains controversial. The present study was performed to evaluate the presence of micronuclei (MN) in the exfoliated buccal cells due to the genotoxic effect of cell phone tower radiation. Materials and Methods: This is an observational study that was conducted with randomly selected n = 108 subjects between 5 and 50 years of age from three school-based localities in Chennai, which were located within the radius of 10–25 m around the mobile towers; exfoliated buccal cells were collected. A smear was made using the collected exfoliated buccal cells and analyzed for the presence of MN. The smear was stained using giemsa stain to evaluate the same. The collected data were statistically analyzed using Pearson’s chi-square test and Student’s T-test. Results: The study results showed that 55.05% of the study population had the presence of MN in at least one field (a total of 10 fields examined), and 45.95% did not have MN in their exfoliated cells examined. The presence of MN was more seen in the 0–10 age groups, with preponderance of the female population (P > 0.05) being statistically insignificant. Conclusion: The presence of MN can be considered as a prerequisite for environmental genotoxicity and adverse health risks due to constant exposure to RF radiation.
