This was the power flux density in the US embassy in 1953-1975, when the USSR radiated the embassy for espionage reasons (Link). A great many employees got seriously ill even though levels were 100,000 times below the US safety limit. The source is, among other authors, Prof. Dr. Gerard Hyland from the Physics Institute of the University Warwick, who was terribly harassed for his bold commitment to spread the truth: His articles were published in scientific journals such as the Lancet and the Microbiological Letters, and he also worked for STOA, a scientific institution of the European Union.

Indoor Equipment Evaluation

This section will grow as I add many measurements I have made... This page is a work in progress.

This last month I attempted to duplicate my quiet computer, but found it incredibly more complicated than I first thought. I need to create an entire table of what components I swapped out and what readings I got... Work in Progress...

Processor speed

The following 2 pictures are both the same ASUS A7V880 motherboard, AOpen 250W ATX power supply, graphics card and memory, running the same MemTest86 v4.1 program,
but if I change the processor, or even just the Front Side Bus speed on the same processor, I can get Wildly opposite emissions of EMR (aka Electro-Smog).

It just got worse and worse...the more I tried to find a quiet PSU...
So the solution is to take the Seasonic SSR-650RM Gold certified PSU away from the backup Sabertooth case, and plug it into the primary computer, ah, much better.
160 alone
_?_ with ASUS A7V880 Athlon2000
Regarding the 2nd Sunpower: Expecting the same model# to perform equally quiet? Nope! Not when it is used.

The Raidmax generated so much line noise, back-feeding into the AC mains, that it interferred with communications scanners and radios. This kind of "dirty electricity" can be measured with the GS meter, or on an oscilloscope, and so is not restricted to complaints of "sick-building syndrome" and ES induced headaches. Actual RF interference can affect other "normal" equipment as well. It's too bad nobody advertises which of their products are low-emissions of the type I'm concerned with.

"Alone" actually means it is plugged into a power supply tester with dummy load, thereby removing the motherboard and components from affecting the test.

If you want to see measurements of microwave ovens, cell-phones, routers, electric cars, masts (cell-towers), and other intentionally noisy or seriously noisy equipment, please search youtube or other pages online. I can't and won't go near them intentionally. My focus is on reducing or eliminating EMF, specifically what those with EHS need to keep their recovery zone clear.

Here are some related youtube links that I liked:
Measuring various cell-phones, wifi, towers, shielding fabric and films with the audio detector, MW1 Electrosmog Detector
Measuring a microwave oven with the COM EM Monitor, a predecessor to the Acoustimeter
Measuring Wi-Fi from a laptop with the COM EM Meter
Measuring Wi-Fi router with the COM EM Meter
Measuring the Wii with the COM EM Meter and the Cornet
Measuring Bluetooth and Motorola celphone with Cornet
Please see more youtube links on the Health Links page.

Units conversion table - dBW - W/m² - V/m
White = Dangerous levels. Some normal people may experience minor effects: stress, headaches, insomnia, mental disfunction (deadly when connected to distracted driving)

Red = Very strong, ElectroSensitive individuals do experience adverse health effects.

Yellow = Warning range. The most sensitive have effects



Green = safe, no effect




Today, electrosensitives are the canary.    They are being ignored.
