Experts Revive Debate Over Cellphones and Cancer

I wonder about all the other radiation, such as from wireless computer connections.

Very few cellphone calls MUST be made. Most of the call time is mindless chatter.

Most cellphones can be jacked to a set of earphones or buds with a short mike, if extended talking is needed.

A headset option that avoids the problem with the wire serving as an antenna right to your head, is a heaset with a tube insead of a wire. Here are a couple options:

I have one and the sound is as good as using the cell phone itself. (I have a Motorola RAZR V3m.)

YMMV.

You could usually tell when you got in the beam - your variometer would totally fritz for about half a second. No other (visible) effect though....

I actually suspect that the real power was aimed to the east, and the feeder beam was what we always intercepted as we flew on the west side. Maybe.

Yup - sounds reasonable to me.

Let’s hear it for comm towers! (without which half our sites would not exist)

Bluetooth does work at lower powers, but it is much closer to the brain. Power density falls off with the square of the distance, so low power closer can be just as dangerous as higher power that is farther away. Bluetooth can use up to 100 mW peak power, and uses the higher 2.4 GHz frequencies (same band as microwave ovens.)

From Wiki:

Evolution of Safety Standards

The following is a brief summary of the wireless safety standards, which have become stricter over time.

1966: The ANSI C95.1 standard adopted the standard of 10mW/cm2 (10,000 microwatts/cm2) based on thermal effects.

1982: The IEEE recommended further lowering this limit to 1mW/cm2 (1,000 microwatts/cm2) for certain frequencies in 1982, which became a standard ten years later in 1992 (see below).

1986: The NCRP recommended the exposure limit of 580 microWatts/cm2.

1992: The ANSI/IEEE C95.1-1992 standard based on thermal effects used the 1mW/cm2 (1,000 microwatts/cm2) safety limit. The EPA called this revised standard "seriously flawed", partly for failing to consider non-thermal effects, and called for the FCC to adopt the 1986 NCRP standard which was five times stricter.

1996: The FCC updated to the standard of 580 microWatts/cm2 over any 30-minute period for the 869MHz, while still using 1mW/cm2 (1,000 microwatts/cm2) for PCS frequencies (1850-1990 MHz).

1998: The ICNIRP standard uses the limit of 450 microwatts/cm2.

I don't believe that either cell phones or Bluetooth headsets are dangerous or cause cancer, but I'm just saying if these doctors are so worried about the effects of a 1 watt cell phone at 800 MHz, they should be just as worried about 100 mW at 2.4 GHz.)

And yes, a corded headset is just as "dangerous," because the outside shield of the cable will conduct the cell phone transmissons and re-radiate them right at the ear, centemeters from the brain tissue. (It's known as the skin effect of RF radiation.)

Dr. Vini Khurana got it right when he said he only uses the hands free mode on his phone. Your best defense against electromagnetic radiation is distance.

Or just don't worry about it.

100 mW is a Class 1 Bluetooth device. Most headsets are Class 2, at 2.5 mW. And it’s just as close as a mobile handset held to the ear.

Bluetooth does work at lower powers, but it is much closer to the brain.

I don't use Bluetooth, so perhaps this is a dumb question. But how can one get much closer to my brain than a cell phone held up to my ear, without doing brain surgery or some such?

Or aggressive nutrition, appropriate for improving ones resistance to all manner of cancers.

Many flip phones have the antenna located in the lower half of the phone, which places the antenna near the lower jaw.

With a Bluetooth headset, the antenna is often in the body of the boom, right over (and sometimes inside of) the ear, and just below the temple.

As I said, it's all semantics anyway, and I'll go with your nutrition answer.

Many flip phones have the antenna ... near the lower jaw.

Ah ok - oral cancer beats brain cancer <grin>.

Thanks.

Off Topic,

Quix,

here’s where I read about the hydrogen peroxide. Looks like a site with a few other topics of interest.
