RE: Comments about your NO NUKES IN SPACE web site (ver. 2003.02.16.002) (follow-up)

August 29th, 2007

Dear Readers,

THANK YOU very kindly for your many comments, suggestions and prayers
for my health. I am honored and grateful beyond words.

Rather than answer each of the dozens of letters individually, which
I will try to do later, when I got up this morning I had a follow-up
from William Emrich regarding NASA's nuclear follies, so I answered
that. His letter and my response are shown below.

Warmest regards,

Ace

Dr. Emrich,

Thanks very much for the response (shown below).

1) You wrote: "Plutonium is no more poisonous than lead" (when ingested).

Here's just one quote (coincidentally seen yesterday in the book
PLUTONIUM: A History of the World's Most Dangerous Element, by Jeremy
Bernstein (Joseph Henry Press, Wash, DC): "[Plutonium] is fiendishly
toxic, even in small amounts." -- Glenn Seaborg. Furthermore, there
is NO logic in your comparison to a gallon of water being used to
"drown hundreds of people." Plutonium is a carcinogen down to the
last atom -- both as an extraordinarily reactive heavy metal, AND as
a radioactive substance.

2) I presented the facts, and you didn't dispute them! You just
didn't like them! As to the "percentage of total atmospheric
contamination" which plutonium represents, the late Dr. John Gofman wrote:

"I am prepared to defend, before any scientific body, and under oath
in full public view, my estimate that ONE MILLION people (perhaps
only 500,000 or as many as two million) in the Northern Hemisphere
have been irreversibly condemned to die of lung cancer from those 5
tons of plutonium. Indeed, were it not for the fact that by far MOST
of the plutonium fell either upon the oceans or uninhabitable land,
the figure of one million would be enormously larger." ("Irrevy" by
J.W. Gofman, 1979, page 39.)

(Below (bottom) is my own recent obituary of Dr. Gofman, who died
earlier this month. Are your credentials half as good?)

3) You don't deny Plutonium-238 WOULD be especially dangerous if it
were released to the atmosphere. What you do deny is that your
little GPHSs, RTGs, RHUs, etc. ever fail. Evidently you failed to
read the DRAFT Environmental Impact Statement for Cassini, which
estimated that ONE THIRD OF THE PLUTONIUM PAYLOAD WOULD BE VAPORIZED
in a flyby reentry accident. This was revised downward in the FINAL
EIS by ASSUMING -- utterly without proof -- that the falling bird
would tumble "just so" so that none of the RTGs would get smashed by
other parts of the spacecraft during reentry. (However, the
supplemental documentation admitted, very subtly, that NONE -- NONE
-- of the RHUs -- each with 2.7 grams of plutonium on board -- would
survive reentry.) That revision of the EIS was repulsively
dishonest. And YOU surely know the truth about the so-called
testing, which, again according to the EIS and other documentation
for Cassini from NASA itself, clearly did NOT reach the temperatures
or pressures that could be reasonably expected. Yes, some GPHSs
would probably survive a reentry. Maybe even most of them. But
others would not. I'd call this one an outright lie on your
part. The RTG containment system you are so proud of would ONLY work
if all three RTGs (in the case of Cassini) were released from the
spacecraft during reentry and none of them banged into any other
parts on the way in. And the RHUs would still have vaporized in any case.

4) "No practical way to generate sign power in the outer regions of
the atmosphere." I assume you meant outer reaches of the SOLAR
SYSTEM and I'm not sure what you mean by "sign" power, but like so
many other NASA scientists, you were obviously careless in that
sentence. In any case, your claim (as I understand what you meant)
is a specious one, since fuel cells could generate the power when
needed at ANY distance from the sun, and even Cassini, which went as
far out as Saturn, could have been solar powered with the technology
available at the time -- you would just have had to carry less
experiments. So the plutonium was UTTERLY UNNECESSARY.

Lastly, my article about tritium is of particular use to people who
live near nuclear power plants and suffer from groundwater
contamination by tritium, where the EPA limit is sometimes reached
and even exceeded. Your comment proves you believe that dilution
solves everything. That is the most absurd view any scientist can
take in this day and age. We know the planet is small, crowded, and
finite, and we ALSO know (with nearly absolute certainty such that
even the BIER VII report could not deny it) that even one atomic
decay can lead to cancer. There is no "threshold."

Your claim that my essay on tritium and K-40 which I sent you
previously "seems biased" is UTTERLY without scientific
credibility. You've basically already admitted it's simply outside
your area of expertise. This after libeling me as if you knew what
you were talking about, and using official NASA email to do so.

Of course, I don't expect you to keep up this conversation, because,
of course, you've said you don't have time. There's never enough
time, but yesterday I learned I have tumors in my bladder and Friday
I go in for surgery. If I can find the time to write this, why can't
YOU find the time for HONEST debate instead of more NASA-sanctioned libel?

Sincerely,

Ace
