Use Cell Well!

Speaking on a cellphone for 500 seconds (nine minutes) is equal to putting your head in a microwave for one second!! A good quality cellphone emits 1 watt of radiation in one second and a microwave emits  500 watt in one second. cellphones and microwave ovens emit the same radiation.

Using a cellphone for 20 minutes increases the temperature of the earlobe by 1 degree.

some precautions:

@Buy one with less than 1.6 watt/kg SAR value.

@Use a land line phone when possible.

@Keep conversations short. Recommended use is six minutes a day! (college guys and girls note this point carefully)

@Call only when signals are proper.

@Use handsfree devices.

@Prefer messaging over calling.

@Switch off your phone when not in use.

@Avoid its use if you are pregnant.

What is SAR value?
Specific Absorption Rate is the amount of electromagnetic radiation absorbed by our body tissue during mobile phone use. In the US the cellular Telecommunications and Internet Association (CTIA) requires all cellphone to comply with the Federal Communications commossion(FCC) SAR limit of 1.6 watt/kg of tissue.
