The mobile phone is a ubiquitous piece in this modern world. An estimated 85% of Americans, 80% of the British, and perhaps 75% of Indians use it, as of today. Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations. Radio frequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body. 1000 participants from outpatient department of a tertiary care center over a period of one and a half years, were included in the study and were divided equally into case (> 1 year use) and control (< 1 year use) groups. Out of 500 cases, maximum 233(46.6%) subjects were using mobile since last 4-6 year and 134(26.8%) were using mobile since last 7-9 year and maximum 344(68.8%) subjects were using mobile 1-3 h/day and 145(29.0%) were using mobile 4-6 h/day.
在当今这个现代世界，手机是无处不在的物品。截至目前，估计85%的美国人、80%的英国人以及或许75%的印度人都在使用手机。手机通过由被称为基站的固定天线网络发射无线电波来进行通信。射频波是电磁场，与X射线或伽马射线等电离辐射不同，它既不能破坏化学键，也不会在人体中引起电离。来自一家三级护理中心门诊部的1000名参与者在一年半的时间里被纳入该研究，并被平均分为病例组（使用时间>1年）和对照组（使用时间<1年）。在500例病例中，最多有233名（46.6%）受试者在过去4至6年一直在使用手机，134名（26.8%）受试者在过去7至9年一直在使用手机，最多有344名（68.8%）受试者每天使用手机1至3小时，145名（29.0%）受试者每天使用手机4至6小时。
