ou can also check with your local (or country’s) citizen action group as some have meters they will rent to you for a fraction of the purchase price. Here’s a list of citizen radiation protection groups to get you started – if they don’t have meters for rent, be sure and suggest this to them!

Detailed Techie Questions?
Please note that I am not an engineer, nor an expert in this technology. I am just trying to figure things out for my own family and then sharing what I learn as I go along. So if you have any specific questions about RF Meters or anything technical, please speak to one of the sellers of this equipment (who I link to above), like Emil:

We received some new questions about this recently:
QUESTION: My 10 year old son and I have been reading your website because he is doing research for a science fair project. I need to purchase him a meter that gives him quantitative data for how much cell phone radiation occurs with a variety of phones. He will compare his data and present for the science fair. By no means, does this have to be 100% accurate, but he must give a good estimate and be knowledgable about the subject. I have seen the Cornet ED-75 as the one to get. I’m personally confused on the different meters out there after reading multiple sources. Could you help by letting us know from your experience which one would be the best, but not the most expensive?
ANSWER: #6 in the blog post above would measure the full range of cellphones, and he can point it at the cell phone antenna to get the reading. I suggest he also measure cordless phones as many are very surprised that they can emit more than a cell phone (especially the 5.8 GHz ones). The ED-75 only goes up to 6 GHz, so it cannot measure some of the cellphones on the market.
QUESTION: If I bought a uni-directional radiation meter (Cornet ED78S), how would I calculate how much radiation a certain spot is being exposed to by the surrounding area? You mentioned starting north and turning the meter 15 degrees until it’s gone full circle. But then what do I do with the data to get an estimate of the amount of radiation in that spot? Do I add all the readings together or take the highest one?
ANSWER: You just take the highest reading – because whatever side of your body is being exposed to that high level, doesn’t really matter – you are still being exposed to it and that’s the highest radiation that’s coming to that spot in the room.
