A couple of things.

First, the paranormal EMF meters won't measure the short wavelengths that the body can absorb so don't waste your money.

Second, the body is susceptible to magnetic fields. Long wavelength fields that eminate from 60 Hz power lines are not easily absorbed by the body. However, impulse noise is rich in very high frequency fields, and these signals have a very short wavelength that the body can absorb.

So, when in doubt, play it safe and limit any exposure that you think may be harmful...
