Introduction

Cellphones have become the heart of life these days. Some people use it to fulfil their communication requirements, some use it for fun and some just need the latest gadget in their hands. There is another aspect that is not discussed that much but bears its importance i.e. cellphones and radiations.

Facts

Research has been going on since many years and cellphones are suspected of many diseases. I start from the ground realities. Cellphones work on microwaves, extreme people call its working similar to a microwave oven. Well its somewhat similar. These microwaves produce heat and may cause disorders to living area around their defined circle. Brain tumors, disorder in human foetus, infertility etc are the main diseases that may be caused by excessive usage of cellphones. The question arises, should we stop using cellphones !!. I must say no or I will say that now its not possible. The above diseases are just an extreme situations, there are lot of preventive measures taken by authorities and people. Lets discuss them.

Preventive Measures

A term SAR ratio got coined i.e. specific absorption rate. SAR is a way to measure the amount of radio frequency energy that is absorbed by the body. A cellphone must pass the FCC requirement of SAR ratio before finding its way to the consumer market. The ratio should be less than 1.6 Watt/Kg. FCC and cellphone vendors provide the value of SAR with every cellphone device. Hence, if you are more concerned with that issue, minimum SAR should be at your top priorities while buying a cellphone.
You can use radiation protectors as an accessroy for your cellphones. People who are during a call for hours can use handsfree for this purpose. But keep another fact in mind that moving the cellphone away from your brain but close to your hips wont remove the disadvantages. A bluetooth wireless handsfree can be preferred as bluetooth is based on radio waves which are not harmful.
