effects of high frequency currents on human body

2007-02-08 Thread emc-p...@ieee.org
Dear all, I'm looking for a guidance on the effects of currents on the human body for frequencies above 100 kHz and up to tens of MHz. I've read IEC 60479-2 and ICNIRP guidelines, but none of them seems to give satisfactory information to set a reasonably safe current/voltage/power limit for an

Paulo, Check out the Bibliography at the end of IEC 60601-1:2005. References [48] to [54] seem to cover this subject, though I think the emphasis is on 50/60Hz currents. Regards, Jon Griver http://www.601help.com The Medical Device Designer's Guide to IEC 60601-1 On 08/02/07, Paolo Peruzzi

Yes, thank you, I know them and I've already searched in between. Unfortunately they don't say nothing about limits (neither IEC 60601-2-3, which could be the only suitable standard). Actually I wonder if there is any scientific and experimental paper or guidance to shed light on this issue. P
