Tring Tring… Tring Tring… Its ringing everywhere… yes it is the mobile phone, a wonderful device invented by Martin Cooper , which is now available with all the latest facilities like wi-fi, internet application, motion detection, organic keypad, touch screen, hi-fi camera and extended memory and in cutting edge designs. It has made our life so simple and fast. It has reduced the distance between the hearts. The mobile phone, also known as cellular phone, has become one of the most successful inventions. The convenience brought by this technology indeed changed the life of many people and society.

Many things such as banking, gathering information such as reports or latest news, control the share market via GPRS etc are what the technology helped to improve and ease the life of people. Japan is the country which the mobile phone technology develops the fastest in the world. But have we ever thought about the harmful radiation waves emitted by these amazing devices when we use them for long hours. Many scientific studies have investigated possible health effects of mobile phone radiations.

The mobile phones have many health issues associated with it. These mobile phones emit harmful radio waves and some part of these radio waves is absorbed by human head. The radio waves emitted by a GSM handset can have a peak power of 2 watts, and a US analogue phone had a maximum transmit power of 3.6 watts. The maximum power output from a mobile phone is regulated by the mobile phone standard it follows and by the regulatory agency in each country. Another major problem caused by the mobile phones is the thermal effect. The continuous usage of cell phones for longs hours can cause heating of head and cornea of eyes and can produce cataracts.

Another area of concern is the radiation emitted by the fixed infrastructure used in mobile telephony, such as base stations and their antennas, which provide the link to and from mobile phones. In order to protect the population living around base stations and users of mobile handsets, governments and regulatory bodies adopt safety standards, which translate to limits on exposure levels below a certain value. There are many proposed national and international standards, but that of the International Commission for Non-Ionizing Radiation Protection is the most respected one, and has been adopted so far by more than 80 countries. Some national radiation advisory authorities have recommended measures to minimize exposure to their citizens. According to these bodies the exposure can be minimized by using hands- free to decrease the radiation to the head and by keeping the mobile phones away from body.
