Single-Strand DNA Breaks in Human Hair Root Cells Exposed to Mobile Phone Radiation

In a 2012 study by Semra Tepe Çam and Nesrin Seyhan, eight healthy human subjects (six women and two men, aged 30-47) were exposed to 900-MHz GSM mobile phone radiation for 15 and 30 minutes to assess DNA damage in hair root cells. Using the comet assay, the researchers found a significant increase in single-strand DNA breaks after both exposure durations, with more damage observed after 30 minutes. The study concluded that short-term mobile phone radiation can cause significant DNA damage in human hair root cells, which may have implications for health issues like cancer, aging, and hair changes. The document also reviewed mixed findings from other studies on RFR-induced DNA damage and suggested further research on the long-term effects and biological mechanisms of DNA repair.
