Good Morning Bob
If I was an X-Ray Tech I would stand behind the lead wall due to the
repeated exposure. Even the patient exposure is limited not only by the
X-Ray intensity but by the TOTAL EXPOSURE. (Intensity X Time) When you
consider the amount of time that an X-Ray tech spends around the X-Ray
source and multiply that by the extremely low exposure then you will see why
there is a lead wall. Yeah the patient is exposed to a higher level but for
a much much shorter period of time. The X-ray tech is there day after day.
One thing to understand is that RF Radiation is DIFFERENT than
X-RAY's. RF Radiation unless controlled by a directive antenna will emanate
from the antenna in a nearly spherical pattern. As a consequence the energy
found at a point distant from the antenna is lower than the energy right
next to the antenna. It is governed by good old mother nature and the energy
decreases as a function of 1/R(Squared). Every time you double the distance
the energy decreases by a factor of four. If you doubt this, there is a good
book that in the very first chapter covers this base material. The book is
titled "The Radar Handbook " by Skoloff. Anyone with a passing grade in
9th grade algebra can read the very first chapter. If you live near a good
size burg then it may be in the library. If it isn't then the library can
borrow it
from another that has it.
You are incorrect in assuming that I do not use a door on the microwave
oven. The oven operates in the 750-1000 watt range and being right next to
it without appropriate shielding is not smart. (Remember the field intensity
drops as a function of distance based on the inverse square law . Plot
1/r(squared) on a sheet of graph paper for better visualization) I can stand
right next to the oven. I usually can't get next to a cell tower antenna.
Ever wonder why there are interlocks on the microwave door so it will not
operate with the door cracked open ever so slightly.
Your cell phone on the other hand operates at a power level of 300
mW(milliwatts): that is 0.3 watts. (Your flashlight bulb burns more power or
do flashlights represent a threat to you?) The antenna is not very efficient
so the radiated energy is down from the 300 mW. The tissue heating if you
place the antenna right next to your head is NOT SIGNIFICANT because of the
area, tissue mass, and power distribution.
Also when you place the cell phone antenna right next to your head the
antenna detunes and the transmitter output drops below the 300 mW. Again any
risk from the RF Radiation is going to be level of exposure times the time
duration of the exposure.
I have used cell phones for years, worked in broadcast and radar facilities
were the transmitter outputs ranged from 50,000 watts to 1,000,000 watts ERP
(Effective Radiated Power).
You cannot pay me enough to walk in front of active ground based
radar antenna within a 1000 feet, but beyond that I would not worry. The
Radar uses a narrow beamwidth antenna which concentrates the RF Energy into
a narrow field that rotates. I have no qualms about working under the
antenna at a 50,000 watt broadcast station or the 1,000,000 watt ERP TV
station while on the ground or nearby because the antennae are far enough
away that my exposure is way below the safe limits.
Oddly enough I am 52 and have outlived in absolute years two of Dad's
siblings who died from cancer. One died at 45 and the other at 49. They did
not work around RF, X-Ray, ionizing or non-ionizing sources. I have had
kidney stones several times and one could surmise that RF caused the stones
but then Dad had stones, he had two other brothers who had stones and his
mother had stones. Sounds more like a genetic/dietary thing to me especially
since we grew up in the Carolina Stone Belt.
By the way, if you are so convinced of your position why do you hide behind
a bogus e-mail address? Surely you know how to set up a temporary e-mail
address on yahoo or msn?
