EMF Protection Magic Carpet Ride

October 8, 2020

A home experiment to reduce exposure to microwave radiation while using a Wi-Fi printer to manually scan documents. An aluminum screen was draped over the printer which greatly reduced radiation levels experienced, even at close range.

Like many Wi-Fi devices, there was no evident way to turn off the Wi-Fi radiation on the printer even when not in use, even while using the printer via a wired USB connection, pictured here.

Thankfully, the sheet of aluminum screen greatly reduced exposure even working adjacent to the printer at very close range.

As the video demonstrates, radiation levels were very strong and constant near the printer, overpowering the radiation meter (the HFE35C High-Frequency Analyzer from GigaHertz Solutions, using an omnidirectional antenna, once considered best-in-class). The meter’s built-in limit is 2,000 microwatts per square meter, when the signal is higher an error is given as shown in the video. (To read the higher level either an attenuator could be added, or a different meter with a higher limit could be used instead.)

Draping the screen over the printer brought the radiation levels down considerably, as well as shielding from additional Wi-Fi coming through the floor from a lower unit. The screen was also comfortable to sit on, although slippery, and could be easily folded back off the printer while scanning documents in order to lift the lid and change documents while still minimizing direct bodily exposure.

This successful trial has implications for anyone seeking to protect themselves from wireless radiation. A sheet of lightweight, flexible aluminum (not steel) screen is a portable and easily applied shield. It can be used as a carpet to sit on or to drape over devices, or to protect from radiation coming through a floor, window or wall. Screen is various widths, here the screen was 48″ wide (4 foot/1.22 meter). This Agent had bulk-purchased a 100-foot roll to shield windows, walls and floors creating the opportunity to experiment with draping a magic carpet techniques.

As with any shielding, testing is required to observe the effects of the shield, as unexpected and unwanted results may occur. Obviously, it would be better to eliminate the source (in this case, to use a non-Wi-Fi scanner) but we don’t always have easy choices about what resources are available.

Is Wi-Fi Dangerous? What Can I Do?

Low-cost meters and many additional ways of mitigating exposure, and reasons for doing so, are described in another recent Meggs Report:

Note: Your Agent Meggsy is available for individual free consult to anyone committed to taking reasonable action to limit exposure.

UPDATE: You might enjoy this whimsical realization that a microwave oven can be used as a safe box for errant wireless appliances that won’t stop irradiating your household:

Meggs holds a Master’s in Public Health (Environmental Health Sciences Division) from the University of California at Berkeley in combination with a Master’s in Urban Planning focused on Sustainable Transportation & Land Use in the International Field, as well as a Bachelor’s degree in Computer Science & Electrical Engineering, with a Minor in Entomology
(the study of insects – as well as pesticides).

Meggs also holds an engineering degree in Computer Science and Electrical Engineering,
also from UC Berkeley.
