To analyze the short-term effects of radiofrequency radiation (RFR) exposure on genomic deoxyribonucleic acid (DNA) of human hair root cells.
Hair samples were collected from eight healthy human subjects immediately before and after using a 900-MHz GSM (Global System for Mobile Communications) mobile phone for 15 and 30 min. Single-strand DNA breaks of hair root cells from the samples were determined using the 'comet assay'.
The data showed that talking on a mobile phone for 15 or 30 min significantly increased (p < 0.05) single-strand DNA breaks in cells of hair roots close to the phone. Comparing the 15-min and 30-min data using the paired t-test also showed that significantly more damages resulted after 30 min than after 15 min of phone use.
A short-term exposure (15 and 30 min) to RFR (900-MHz) from a mobile phone caused a significant increase in DNA single-strand breaks in human hair root cells located around the ear which is used for the phone calls.
分析射频辐射（RFR）暴露对人发根细胞基因组脱氧核糖核酸（DNA）的短期影响。
从 8 名健康人体受试者在使用 900MHz GSM（全球移动通信系统）移动电话 15 和 30 分钟前后立即采集头发样本。使用“彗星试验”测定头发根细胞中单链 DNA 断裂。
数据显示，使用移动电话通话 15 或 30 分钟会显著增加（p <0.05）靠近电话的发根细胞中单链 DNA 断裂。使用配对 t 检验比较 15 分钟和 30 分钟的数据也表明，使用手机 30 分钟后造成的损害明显多于 15 分钟。
来自移动电话的短期（15 和 30 分钟）RFR（900MHz）暴露会导致耳部附近用于电话的人发根细胞中 DNA 单链断裂显著增加。
