Some will probably be skeptical, but I've actually felt the effects
of RF when operating on the HF bands. I forgot what band it was, but
it was one of the lower ones, "80 or 40", and I was working CW from
my mobile. "parked"
It took a QSO or two before I realized the RF was effecting me.

I believe you. I have felt the effects of using a cell phone for an
extended time. A warmth sensation. And not the batteries.

There is no question that at some level, tissue heating is noticeable, and I
can attest that RF burns tissue at higher levels. When working in the near
field of antenna farms this helps you to determine where you should linger
and where you shouldn't. Some people linger in the sun too long. Some
people are more sensitive to tissue heating than others. Still, after
working in the near field of 900 paging antennas with ERPs of 1 to 10 kw,
along with numerous other antennas it is hard for me to imagine that a 300
mw cell phone could even be sensed, let alone cause damage. I have seen
people who actually complain of RF symptoms with the power off, even in
anguish as if in pain or being tortured, conviced that they were being
exposed, while thinking nothing of it when they actually were. It would
seem to me that a great many people are highly suggestable as evidenced by
the changes in our society to conform to media demoralization. There is
even commercials for HULU that makes great light of this. Yuri Bezmenov,
who defected from the KGB in the 70s warned us about their constant and
unrelenting demoralizion techniques to render whole societies unable to come
to rational decisions even when confronted with the obvious. He joked that
they could tell you the sky was Black so often, that even when they showed
you it was really Blue, you wouldn't believe it.

Someone mentioned hearing loss. This is an issue I have noticed, but not
from RF but from high frequency noise. Many people didn't like CDs because
they didn't sound right, and Solid State amplifiers when transitioning from
Tube types. Now with some DSP implementations. I noticed this right away
with a certain radio that didn't sound bad but was completely irritating and
fatiguing to listen to for more than a few minutes until I started using an
external speaker with a tailored response. Subsequent to that episode I
experienced an overnight hearing loss in one ear of all frequencies over
about 1500 Hz in that ear along with a peak at that frequency that is quite
tender. It is a known fact that CW ops who use headphones are more prone to
hearing loss, so I would really like to see more research and solutions
there.

I`ve always thought the only effect if RF on humans to be heat and
burns from my personal experience of extreme exposure throughout my long
life. I`ve spent years with a megawatt all around me. Recently i`ve read
the defense department has a nonlethal highpower pulsed micrlwave weapon
which incapacitates anyone in its beam. It is also said the military has
little interest in nonlethal weapons.

At Texas A&M in the 50's, we had a radar in the
EE building with the antenna on the roof. Once,
someone was working on the antenna when someone
else turned the radar on. They rushed the guy
on the roof to the hospital in an ambulance. I
don't recall the rest of the story.

This would all depend on the type of Radar, and it's specific
Transmitting Characteristics. Some military radars of that era
were in the Megawatt Peak Pulse Power range, and these "could" have
Biological Issues in the near field. Very few radars of that era,
were CW, Frequency Agile, or Spread Spectrum Radars, with High Power
CW outputs.

Much more likely, would be the Antenna, smacked the guy, physically,
and, or knocked him off the ladder, he may have been standing on,
when it started turning, unexpectedly.... This type of injury is
still very common, even on commercial Marine and Aircraft Search Radars,
that don't have the Peak Pulse Power Levels, even at the Antenna Radiator
Surface, to cause Biological Heating Issues.

cancer?

The correlation is 1.

There are radio waves and there is cancer.

Correlation does not imply causality.

The ONLY effect that radio frequencies can do to humans is thermal.
You have to increase the frequencies to the upper visible region
(blue since we are talking frequency rather than wavelength) before
there is any ionizing radiation. Note, however, that thermal effects
can be damaging.

I have two books on industrial applications of microwaves that
describe where the early Litton devices were first used in
restaurants (but the books are in Tennessee and I am in SC so I
cannot provide references). It was found that at many restaurants,
the doors were taken off the units and the ovens were operated
continuously. Litton soon provided interlocks on the doors!
People would place food into the cavity without turning off the
microwaves. Other than a few thermal burns, no one was seriously
hurt by the ovens — with one exception. In fact, I would be quite
willing to place a hand into an operating home microwave oven for
several seconds at a time. With reasonable blood flow, the thermal
energy is quickly spread out to the rest of the body. But the
exception is quite serious. The cornea and lens of the eye have
essentially no blood flow, so any heat generated there builds up.
This can produce cataracts. The effect was seen among many early
experimenters with microwaves and many members of the military.
working with high power radars. So while the new weapon Richard
talks about is non-lethal, it can easily cause blindness. This may
be why the military is not so interested.

I have seen demonstrations of one of these devices on one or another
cable channel. I believe they mentioned a frequency in the 60GHz range.
They also mentioned the penetration depth on skin was something like a
mm. The effect is supposed to feel like instant extremely severe
sunburn. You WILL leave the area immediately. They tested it on one of
the hosts of the show. He moved out of the area of the effect very quickly.

Given the desire of the subjects to get the hell out of Dodge when the
system was pointed at them, I doubt cataracts would be an issue.

Don't take any numbers I stated here as correct, it was a while ago.

Tom,

I have seen the video too. But 1 millimeter penetration depth is still
enough to do serious damage to the eye. I doubt if this weapon ever
makes it into production. Is anyone familiar with the Hague Conventions
in relation to this?

Well, not exactly. Pulsed RF can be "heard". The original 1962
article:

Military applications:

There's also some research into resonant vibrational effects of the
modulation frequency (i.e. GSM 217Hz buzz) on various cellular
structures. I don't recall the results (and am too lazy to find
them). Light reading:

Suggestions for furthur research:
1. Why does expsosure to RF seem to cause a compulsion for beginning
hams to upgrade their licenses?
2. Does the presence of RF cause cell phone users to yell into the
handset, while non-RF POTS phone users show now such tendencies?

I installed a 10-foot TVRO at home in 1985 and read an inordinate amount of
material on the subject in the 1980's. I read a "don't let this happen to
you" story about an experimenter who supposedly used a microwave oven
magnetron as a local oscillator for his own TVRO. He didn't shield it
properly and received fatal heating injuries to his internal organs.

Possibly BS, possibly accurate. I tried finding some reference to it on the
Internet but was unsuccessful. Anybody remember the story?

The LO for a C-band TVRO is 5150 MHz, nowhere near a Microwave oven freq
(2450) but its second harmonic, 4900, is a candidate for block
downconversion of some of the channels.

Article 23(e) of the 1907 Hague Convention prohibits the use of "arms,
projectiles or materials calculated to cause unnecessary suffering."

Great ... now define "unnecessary."
