    Eleanor White's comments on this posting:

    This book focusses on NON-ionizing radiation, and contains
    detailed texts about NON-THERMAL effects.  In other words,
    "right up our alley".

    The main use of this book is to show that it is easy for
    electromagnetic signals to cause radio frequency hearing and other
    effects at LOW power levels.  This in turn can be used to explain why
    DETECTION is so very difficult.

    I don't understand the biological jargon, however, a few of the more
    plain-language paragraphs STUNNINGLY verify that with careful choice
    of signal frequency and modulation, not only can the body's cells
    detect the modulation envelope of an incoming radio signal (i.e.
    function as a "cellular crystal set") but even AMPLIFY these
    carefully formed signals.  (Amplification of other effects, such as
    proneness to disease, is also covered in the book.)

    "Detection", in terms of radio signal reception, means that some
    portion of the reciever "rectifies", that is, turns the AC of the
    incoming signal into varying DC.  If this conversion is not done,
    voice to skull wouldn't work.

    The book touches also on ways in which cells communicate, and
    shows that electromagnetic fields of relatively weak power levels
    can affect intercellular communication, which is, as I understand
    the subject, what the brain is "all about".

    Bio-amplification is apparently why radio signals of very low average
    power ("MICROwatts" per NASA) can still produce audio effects,
    and no doubt plays a part in difficulties in detection.
