Electro magnetic signal transmit from cell phone antenna Note: The increased use of cell phones has brought about serious concerns regarding the probable health hazards. This is because mobile phones use electromagnetic radiation in the microwave range.

Thermal Effects  Heat generated on the face by 15 minutes of cell phone use due to their electromagnetic radiation
 
Radiation Penetration in the head of an adult, ten-year and five-year old When radiation hits the head, it penetrates the skull. The pictures above are the result of an experiment show how radiation penetrates the skull of an adult (25%), 10 year old (50%) and a 5 year old (75%). The younger the child the deeper the penetration due to the fact their skulls are thinner and their brains contain more fluid than adults’. Radio frequencies travel through children’s brains much more easily and therefore increase the risk of cancer.
 
 
It is not only the choice of phone, but how you use it that is important when you want to control the amount of radiation you are exposed to. Here you will find a few simple tips that can considerably reduce radiation and therefore also health risks .  Consider the following when using your mobile phone
Use a handsfree set The further away from your body the phone is, the less radiation you are exposed to. Using a hands-free set is the easiest way to radically reduce the amount of radiation you are exposed to if you use a mobile phone.
Hold it at the bottom By covering large areas of the phone with your hand, you reduce its ability to send and receive signals. The phone then increases its power and transmits stronger radiation to compensate this. So hold the phone as far down as possible, so it can operate at low power.
Get in the best position You can see the signal reception strength in the display. When reception is good, the phone reduces power and radiation. If reception is poor, the phone uses maximum power and radiation.
Don’t talk too long and Use regular phone if possible The radiation you are exposed to is directly related to the time you spend talking on your phone. For linger calls it is safer “and cheaper” to call from a regular phone.
