1. Cell phones
By D-Shaham

2. What are they?
Cell phones are used every day by humankind in order to communicate with one another:
In the car, at home and on the street.

3. The tower
The tower is what transports the signal from 1 phone to the next via RADIATION.

4. HAZARD!
When one makes a call the phone works hard to reach the tower in the start and so there is radiation near that person’s head=goes into the body.

5. Gamma & micro radiation
A couple days ago in science class I did a gamma and found out that the radiation gets weaker with distances. Then Dr. B told us that it’s the same thing with cell phones.

6. conclusion
Always keep your phone away from your head when you call someone so as to minimize the threat of radiation. Another thing you can do is keep it on speaker the whole time.
