Cell Phone Rf Radiation

Cell Phone RF Radiation

Question:

Do cell phone cases effect the amount of RF radiation being emitted by a cell phone

Hypothesis:

Cell phone cases will all lower the levels being given off of the cell phone

Main Subject Of Interest:

Radiation has always interested me. Cell phone radiation has shown up in the media quite frequently, and I felt it would be fascinating to measure radiation emitting from cell phones. This project seemed very interesting to me, so I chose to do it.

Bibliography:

Before beginning my project I referenced the following website to give me a basis on the research I wanted to conduct.

Control:

For the control, we placed the cell phone by the receiver which was connected to an amplifier and a spectrum analyzer. We recorded the average dbm levels and used that as our basis.

Variable:

The variable that was changed throughout the experiment were the styles of phone cases. We swapped out the phone case between tests to see how the case would affect the radiation levels.

Conclusion:

I hypothesized that cell phone cases would all bring down the RF radiation levels. However, some had little effect, some lowered the levels, and some amplified the RF radiation levels. Therefore, my hypothesis was incorrect.

        RF radiation is a form of radiation that is given off by cell phones. RF radiation is what is called a non-ionizing form of radiation, so it has no link to increase risk of cancer. It can have a sort of microwave effect on you tissue from the radiation which causes heating of the tissue. I was wondering if the RF levels would be affected by whatever cell phone case is being used on the phone.
