phones, cordless phone, WiFi, surveillance bugs, microwave ovens, etc.) from 1 MHz – 8 GHz. More details…
7. 8 GHZ RF Meter (Tri-Field $499 – Ships from USA) – For me, this meter is the best use of my money for what I want to measure. Because I blog about this issue, I write letters to government officials and school admin people, I need to be as accurate as possible and I need to back up my assertions with specific data. This meter is 3-axis (no need to rotate), it measures from .0001 microwatts/cm2 up to 3,000 microwatts/cm2 and it covers from 10 MHz – 8 GHz – so it will measure every wireless device around (including surveillance bugs!), plus leaving room for future technology developments. This meter also measures electrical fields. For the informed layperson (like myself) this is probably the best combination of needed features and ease of use. More details here… I plan to do more blog posts and also some videos showing you how to measure your home, school, office, etc. so be sure and SUBSCRIBE to my blog so you’ll be notified.
8. 8 GHZ RF Meter (Tri-Field, $345 – free shipping) – This meter has all the features of the meter above in #7, but this meter ships from Israel, while the one above is in the USA. So your shipping time is going to be a bit longer on this one, about 2 weeks, but, the great thing is, the shipping is free. I have ordered from this company myself to test and everything went smoothly and the meter arrived in 2 weeks. As I said above, if you want to be able to test EVERYTHING, with ease – because this measures the radiation coming from all directions (tri-field), so you don’t have to keep turning and re-measuring, until you’ve measured a full circle – you can just stand in one spot, facing any direction and it will measure ALL the radiation coming from every direction to that spot – then this is the meter to get. More details here…
For people who need to get more specific, there are more complicated meters for this, but of course, they are also much more expensive (thousands of dollars).
You 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
