Earth yourself

No, potential is local property of the field. 
Potential difference is probably what you meant?

Yes.

so if this is scam can any one make an explanation about why is a scam?

because he sell $1 product at $1000 price.

heheh thats another history then,
thing does the work was designed for, 
the main topic is know if the fact of ground yourself is healthy or the lectures the multimeter are showing, are something else than dropping static energy

you should already know from previous discussion. the thing works as described (grounding mate) is being used everywhere. i was answering OP's/yours another question.
next product for this guy is EMF safety magical strap/bracelet (which the 1st picture will cost the same as the 2nd picture below)

When you ground yourself you become a quarter-wave dipole tuned to about 44MHz.  As with any antenna there will be RF current flowing through it. 

And at 88MHz you're a dipole, when you're not grounded. I do remember reading that low VHF is the most dangerous band of non-ionising radiation, presumably for that very reason. As far as every day life is concerned of course it's of very little consequence, unless you're working around a high powered VHF transmitter.

I can see clearly now.  2080.  Long term DNA damage from permanent exposure to HF and VHF RF has been finally and conclusively proven. Some 1980's scaremonger has been ascended to prophet status because he "predicted" it without understanding what he was talking about.  G73 governments pledge 10 quintillion "old" dollars to reduce their RF footprint.  New dollar has been denominated by a factor of 1000.

Too bad we won't be around to bet on it.

Don't you think it's weird that it only took 20 years or research to conclusively prove tobacco, asbestos and harmful ionising radiation all cause cancer, yet low energy non-ionising radiation has been subject to a similar level of study but no clear link has been shown?

Because cancer is very easy to detect and research - cancer cells are different from normal ones.  Personally I don't believe RF will be found to cause cancer.  DNA mutation in ordinary cells is completely different process.  It is pretty natural process if you believe Darwin was right.  RF exposure might be gently pushing towards malign mutations path.  Or it might be not.  This will take a good few generations to prove.  I know jack about this.

Cat Dander,Duck poo,Beer & tea may also be mutating us,but seeing we are fairly complex beings,it may be several millions of years
before it makes much difference.

That's why scientists perform experiments on smaller mammals with shorter life cycles than us.

Then there's the cost/benefit analysis. Suppose it's proven that mobile phones increase the cancer rate by one in a billion over a ten year period, does that mean they should be banned? Of course not, they probably save more lives than that.

Really? Please explain the difference. Why is UV radiation linked to skin cancer, or ionizing radiation linked to various forms of cancer? My understanding is that it's DNA damage causing a change in cell cycle (eg. something wrong with the checkpoints) through activation of some oncogen (extremely simplified version).

DNA mutation outside gametes is insignificant unless it causes change in behavior. The only mechanism that springs to mind for a small number of cells to cause damage is cancer. Of course if the change effects a significant fraction of the cells, you might be in trouble. But it would be more like accurate radiation sickness at that point, not a small cumulative effect.

It is pretty natural process if you believe Darwin was right. 

Which is why there are various mechanisms to repair DNA damage. It only tends to become a problem when these mechanisms get overwhelmed. This is why some exposure to UV (eg. sunlight) is usually harmless, but too much is associated with skin cancer.

RF exposure might be gently pushing towards malign mutations path.  Or it might be not.  This will take a good few generations to prove.  I know jack about this.

Sure, mutations in gametes may cause birth defects. Do you have a proposed mechanism for low energy electromagnetic radiation to cause eg. point mutations? A claim like 'this may cause troubles in 70 years' is hard to verify. The only thing we can say is that we haven't found a strong correlation yet. Plus the logical issue of proving the absence of harmful effects. Is there any substance or technology that has been proven to be harmless? Even oxygen may cause harm if the concentration in the blood is too high (decompression sickness).

Non-ionising radiation is basically harmless unless you're exposed to a high power source. The only effects on the body are due to heating of the tissues which has been proven over and over. Even harmless visible red light can kill you if you're exposed to a high enough energy source i.e. a high powered laser. The only reason why micowave frequencies are any more dangerous than visible radiation is because you can't see them and they penetrate the skin deeply, heating more sensitive parts of the body. Even lower frequencies are less harmful because the human body is too small relative to the wavelength to absorb a significant amount of radiation.
