PROJECT TITLE:Cell Phone Radiation

 Purpose: The purpose of this project is to quantify the amount of radiation emitted from different sides of various types of cell phones when it’s on standing and calling mode from various distances.

Procedure: First build the jig. Build the jig so that you can easily measure microwave radiation emissions. The jig is a way to securely and accurately hold the phone a set distance from the microwave leakage detector. Making a jig will allow you to make measurements at the same distance for every trial. Afterwards test the radiation of each phone from the front, back, bottom, and top from 2 cm, 5cm, and 15 cm, for standby mode (record the radiation leakage after waiting for 30 seconds).Then test the radiation of each phone again from the front, back, bottom, and top from 2 cm, 5 cm, and 15 cm, but for call mode (wait for 30 seconds before recording). Make a call on the cell phone to your volunteer. When the call is answered, take the microwave leakage measurement. Record the leakage value in your lab notebook. Do at least 3 trials for each. Repeat each part for each phone.

Conclusion: In conclusion all of the hypotheses were correct. We can conclude that old phones have less radiation than smart phones. This is because that older phones have fewer functionalities than smartphones. The reason different phones emitted more radiation from different sides is because of their manufacturing build. Although the peak amount of cell phone radiation is lower than the maximum acceptable levels (5 mW/cm²), it is not clear from current data whether exposure to low levels from cell phone use over a long period of time is dangerous to human health.
