Can Human Bodies Tolerate High Frequency Electrocution at 100 KHz?

[Frenemy90210]

Is it correct to say that human body can tolerate mains (household) current 120/230 V if it is at high frequency (such as 100-200 KHz instead of 50/60 Hz) ?

Also, since induction cookers operate at high voltage around 100 KV and high frequnecy of around 100 KHz . do they not generate very powerful radio noise ?

It seems so. "Other issues affecting lethality are frequency, which is an issue in causing cardiac arrest or muscular spasms. Very high frequency electric current causes tissue burning, but does not penetrate the body far enough to cause cardiac arrest (see electrosurgery)."

Tolerate isn't exactly the word I'd use.

According to "The Skin Effect and Another Reason Why Tesla Coils Don't Shock" once frequency is above 5 kHz, nerves no longer register a sensation of shock, but that doesn't mean there is no effect. The Health Physics Society has a piece on RF radiation, and look up short wave diathermy.
