• Mobile phones have changed our way of life but are they safe? Mobile phones were introduced in the 1990’s. They are now more than a million in use.

• In this project we will be looking at the health hazards and are they true.

• Mobile phones work by sending and receiving tiny microwave signals.

• They send them to the nearest phone masts which send them to their destination.

• They also send other messages to other phones.

• When your phone is switched on, it sends a signal to the phone mast to say, “I am here.” Then the phone mast locks on to its position.

• Scientists say that the mobile phone cooks your brain.

• Microwaves that the phone gives off goes in any direction.

• The microwaves are often absorbed by the thick bone of your skull or they pass through your skull and into your brain.

• These signals are so tiny you cannot feel them. Your brain becomes heated by the tiny microwaves but you cannot feel them.

• This does not mean that your brain becomes heated straight away. It does this over many years.

• Disadvantages of having a mobile phone.

• Mobile phones may cost a lot of money.

• They can cause the brain to heat slightly.

• For:• Mobile phones can help you

when you need help.• Mobile phones will improve

your lifestyle.• You can do many things on a

mobile phone.• Mobile phones are a tiny

miracle.

• Against:• Mobile phones have

been thought to cook your brain.

• They have also been thought to cause problems with the human body.

• They are also expensive to buy and can cost a lot to replace.

• Mobile phones have improved our way of life.

• But they can cause problems.

• They do emit microwaves but this should not affect us.

• So it is your choice whether you buy one or not.
