Typical Level and Safety Standards of DC Electrical Fields

'DC ELECTRIC FIELDS (Electrostatics)

Sources: Earth, "synthetic carpeting, drapes and textiles, vinyl wallpaper, varnishes, laminates, stuffed toy animals, TV or computer screens... Measurement of electrostatic surface potential (V) as well as discharge time (s)"

Typical DC Electric field levels inside older homes built on a crawl space

There needs to be two typical readings in homes: Older homes built on a crawl space and newer homes built on a concrete slab. Homes built on a crawl space would have readings higher than earth's electric field.

I did not find a source. Please post if you do.

Typical DC Electric Fields inside Newer Homes Built on Concrete Slabs

Homes built on a concrete slab would have lower DC electric field than the earth's DC electric field. Concrete slabs can block earthing.

"Can I receive grounding energy through ceramic tiles? It depends on what the tiles sit on. If they are on a concrete slab or on the ground, the energy could come through. If the tiles are atop plywood or some other kind of wood, plastic, or vinyl understructure, they will not likely be conductive. The type of tile also factors into the mix: ceramic tile with a glazed finish on the surface will, like glass, probably prevent the Earth’s energy from coming through.

Q: I have a concrete floor in my garage, but I remember seeing insulation and maybe a plastic vapor barrier put down in the foundation before the concrete was poured...would that concrete floor still provide earthing benefits? What if even part of the concrete went all the way into the Earth?

If there is insulation, and perhaps a plastic barrier before the concrete was poured, the concrete will very likely not be conductive. If however, some of the concrete slab does come in contact with the Earth, then the whole slab will very likely be conductive."

How to ascertain whether concrete slab is on top of insulation and a plastic barrier? Consult county building codes.

Typical DC electric field outdoors on ocean sand, lawn or dirt

Earth's electric field across temperate latitudes fluxuates 40 - 50 uT. Equivalent to 400 mG - 500 mG.

Typical DC Electric Field Outdoors on Asphalt

Asphalt blocks earthing.
