PLEASE FORWARD TO GEGOGE NOOREY, COAST TO COAST AM
NAYBE HE CAN TELL THE TRUTH ABOUT SOMETHING!!!!

the best part of this "report" comes, when Mr. Alan Bean
says: "That´s bullshit." and there is no better word to
describe what the editors of this stuff made: BULLSHIT
That said... I still can't understand how he wouldn't know
about the Van Allen belts.
Fox TV and the Apollo Moon Hoax
(February 13, 2001)
On Thursday, February 15th 2001 (and replayed on March 19),
the Fox TV network aired a program called ``Conspiracy
Theory: Did We Land on the Moon?'', hosted by X-Files actor
Mitch Pileggi. The program was an hour long, and featured
interviews with a series of people who believe that NASA
faked the Apollo Moon landings in the 1960s and 1970s. The
biggest voice in this is Bill Kaysing, who claims to have
all sorts of hoax evidence, including pictures taken by the
astronauts, engineering details, discussions of physics and
even some testimony by astronauts themselves. The program's
conclusion was that the whole thing was faked in the Nevada
desert (in Area 51, of course!). According to them, NASA did
not have the technical capability of going to the Moon, but
pressure due to the Cold War with the Soviet Union forced
them to fake it.
Sound ridiculous? Of course it does! It is. So let me get
this straight right from the start: this program is an hour
long piece of junk.
From the very first moment to the very last, the program is
loaded with bad thinking, ridiculous suppositions and
utterly wrong science. I was able to get a copy of the show
in advance, and although I was expecting it to be bad, I was
still surprised and how awful it was. I took four pages of
notes. I won't subject you to all of that here; it would
take hours to write. I'll only go over some of the major
points of the show, and explain briefly why they are wrong.
In the near future, hopefully by the end of the summer, I
will have a much more detailed series of pages taking on
each of the points made by the Hoax Believers (whom I will
call HBs).
So let's take a look at the ``evidence'' brought out by the
show. To make this easier, below is a table with links to
the specific arguments.

The Question
(Submitted February 28, 1997)
I wonder if you could tell me exactly what the VAN ALLEN
BELT is and how much radiation does it contain, ie how many
rems of radiation are there out there? Plus, what protection
would organic life need to be protected from this radiation?
The Answer
David Stern, a researcher in another lab here at Goddard,
has graciously supplied an answer to your question, given
below:
"The radiation belts are regions of high-energy particles,
mainly protons and electrons, held captive by the magnetic
influence of the Earth. They have two main sources. A small
but very intense "inner belt" (some call it "The Van Allen
Belt" because it was discovered in 1958 by James Van Allen
of the University of Iowa) is trapped within 4000 miles or
or so of the Earth's surface. It consists mainly a
high-energy protons (10-50 MeV) and is a by-product of the
cosmic radiation, a thin drizzle of very fast protons and
nuclei which apparently fill all our galaxy.
" In addition there exist electrons and protons (and also
oxygen particles from the upper atmosphere) given moderate
energies (say 1-100 keV; 1 MeV = 1000 keV) by processes
inside the domain of the Earth's magnetic field. Some of
these electrons produce the polar aurora ("northern lights")
when they hit the upper atmosphere, but many get trapped,
and among those, protons and positive particles have most of
the energy .
"I looked up a typical satellite passing the radiation belts
(elliptic orbit, 200 miles to 20000 miles) and the radiation
dosage per year is about 2500 rem, assuming one is shielded
by 1 gr/cm-square of aluminum (about 1/8" thick plate)
almost all of it while passing the inner belt. But there is
no danger. The way the particles move in the magnetic field
prevents them from hitting the atmosphere, and even if they
are scattered so their orbit does intersect the ground, the
atmosphere absorbs them long before they get very far. Even
the space station would be safe, because the orbits usually
stop above it--any particles dipping deeper down are lost
much faster than they can be replenished.
"If all this sounds too technical but you still want to find
out-- what ions and magnetic fields and cosmic rays are,
etc.--you will find a long detailed exposition (both without
math) on the World Wide Web at:

Good luck!
David Stern
Note:
Another point of particular interest to us in high-energy
astrophysics is the South Atlantic Anomaly. This is a region
of very high particle flux about 250 km above the Atlantic
Ocean off the coast of Brazil and is a result of the fact
that the Earth's rotational and magnetic axes are not
aligned (see
http://www.oulu.fi/~spaceweb/textbook/radbelts.html).
The particle flux is so high in this region that often the
detectors on our satellites must be shut off (or at least
placed in a "safe" mode) to protect them from the radiation.
