The Problem: The TCO 99 standard from the FCC limits EMF (electromagnetic frequency) exposure to 2 mGauss, the term used to measure electromagnetic frequency, at a distance of 30 centimeters away from the front of a computer monitor. If I apply the regulation to 20 cell phones, how far do I have to be from a working cell phone to get an EMF reading of 2 mGauss, and will they comply with the TCO regulation?
It is hypothesized that a majority of the 20 cell phones that will be tested will conform to the regulation. To reiterate, at least 11 out of 20 of the cell phones will register 2 mGauss at a distance nearer than 30 centimeters.
So basically, I am using a guassmeter to measure and record if a cell phone's distance to 2mGauss is less or more than 30 centimeters. I just realized I don't have a control. :( :( :( :(
If you need more information, ask! I have it all on a word doc. Ready to copy and paste over.

Don't be afraid to give me more work.. I've got time. Think up a control experiment for me to do. I can *not* think of one to do.

The control would be a CRT computer monitor. You demonstrate that the meter in question measures the 2MGauss at the specified distance for the CRT or at least get a reading at a standard distance for the CRT. Its possible that the CRT you use producess less Gauss than expected.
Then using the same meter you measure the cell phones. You can now compare the cell phones readings against what a CRT wil produce.
