That means that she is getting to our young people and poisoning their minds
with her scientific sounding gibberish. I would really welcome a detailed
rebuttal to this video being posted at DIGG and at Youtube or wherever the
Snowshoe Films video has been posted. They also have Doug Rokke anti-DU

The "59.5 neutrons/g/hr" rate (I neither confirm nor dispute its
validity) translates into about half a neutron/year/micro-gram; a
micro-gram being a much more likely unit for inhalation (It you've
inhaled a full gram of metallic uranium, you should live so long as to
have spontaneous fission be your biggest health concern.)

Elaine Hunter and Cathy Garger's latest speculation - now, they are
concerned that spontaneous fission is the cause of the birth defects - I
appreciated being advised by a sharp eyed RASAFer that the British
Medical Journal published one of the so-called DU victims with an
unknown skin disease and received a number of electronic replies telling
that it was not unkown and naming it.

Look for the spontaneous fission products of U-238 to find an important
cause of increased rates of birth defects in Iraq [and other places] and
the cause of, for example the virulent, aggressive and deadly cancers of
deceased veteran Dustin Brim and others.
Whoever claims that there are no fission products associated with the
use of concentrated "depleted" uranium has just plain not done their
homework.
I've read such claims. They are WRONG.
The case for fission products when DU munitions are used, especially
aerosolized, is exactly the same as the case for neuton emissions [and
really I'd hoped someone else would notice and write an email about it].
We must get beyond alpha and consider the whole radioactive/toxic
alphabet soup when DU munitions are used if we are to fully profile this
insidious, surreptitious serial killer.
Here it is again:
THE CASE FOR FISSION PRODUCTS FROM CONCENTRATED "DEPLETED" URANIUM
[you don't have to be a nuclear physicist, just have some reading
comprehension]
1. Rate of Spontaneous Fission Neutrons From Uranium is 59.5
neutrons/g/hr [According to one reference [
iop.org/EJ/abstract/0370-1298/65/3/307 from Proc.
Phys. Soc., D.J. Littler, 1952: "A Determination of the Rate of Emission
of Spontaneous Fission Neutrons in Natural Uranium"] the rate of
emission of spontaneous fission neutrons from natural uranium is
computed to be 59.5 neutrons/g/hr of uranium.]
2. Uranium-238 Undergoes Spontaneous Fission at a Rate 35X That of
Uranium-235 [According to another reference:
[www.mcgoodwin.net/pages/otherbooks/rr_darksun.html
], Uranium-238 undergoes
spontaneous fission at a rate 35 times that of Uranium-235.]
><>
Though U-238 is not fissile, which means it does not sustain chain
reactions, it is indeed fissionable, spontaneously fissionable.
Now, if natural uranium [U238 + U235, +U234] undergoes spontaneous
fission at a certain rate, and U238 undergoes spontaneous fission at a
higher rate than U235 here's what happens:
Concentrated "depleted" uranium has had most of the U235 and U234
removed from the mix; gaseous diffusion sends the lighter isotopes and
heavier ones to two different streams in the process. [The Revenooers
don't mind this kind of still, they get their piece of the pie and if
they ain't no moonshine still within a couple of miles of home... but I
digress]. Anyway, the result is that the spontaneous fission rate of
what we call DU will not be less than natural uranium. A tiny bit more,
in fact, but I'll spare you the math on that.
Also, I'll spare you the math on how many tons of the stuff was
used--still under debate-- and go with the imprecise "a whoppin' lot."
So there's MUST be fission products. On Wikipedia one can find listing
of fission products for U-235. Those from U-238 are probably similar.
Some have long half-lives, some short. ALL are radioactive. Don't fool
yourselves, given the opportunity the ones with short half-lives will do
the most damage to health because of rapid rates of radiative decay.
Here's an unknown consideration at least for me. When a vehicle is
incinerated there is an intense thermodynamic event. I do wonder if the
extremely high temperatures increase the rates of fission product
emissions.
In addition, the neutrons released will transmute some of the
materials involved into radioactive isotopes.
Really the scenario is extremely complex. Mind boggling.

Hi, George.
I completely agree that SF is going on in DU: I even agree that the rate
is higher (by a very, very small amount) than in an equal amount of
Unat. What I was trying to say was that I hadn't checked on the rate
given, and that I was accepting it for the purpose of doing the
calculation. SF is an interesting and, in some situations, an important
consideration. I remain unconvinced that DU exposure is one of those
situations.

Sorry, in my haste, I left the tittle intact, with no intention to equate
spontaneous fission with any sort of effect whatsoever. We treat the few
neutrons present as being only a scientific curiosity and a nucleonic
metrology measurement challenge.
Personally I remain neutral concerning *low dose* radiation as being either
helpful or harmful, as there seems to be no overwhelmingly clear correlation
either way.
Maybe I'm lucky, but I grew up playing in lead mine tailing piles as if they
were sand piles, lived around and
worked chemical plants all my life, and no doubt received more than my fair
share of neurton irradiation, and certainly gamma radiation over a
long period of time with no ill effects.
ALARA makes sense, and most professionals follow it with caution but not
paranoia.

A short calculation:
The effective SF decay rate of 238U is lambda=2.678e-24 s-1.
1 mol = 238 g of 238U contains A=6e23 atoms with an activity of
lambda*A=1.6 SF decays per second
I did not find a nu value for spontaneous fission of 238U; for fast
fission it is 2.819 (http://www-nds.iaea.org/sgnucdat/a6.htm ), which is
a conservative estimate for SF (I think). Thus we find 1.6*2.819=4.51
n/s per mol due to SF, or 0.019 n/s = 68 n/h per g 238U. For 1 ug this
is about 1 neutron every 609 days. Wow.
68 agrees well with the quoted number 59.5.

Lab disinfectant harms mouse fertility
Two chemicals widely used in cleaning agents for homes, offices and hospitals cause birth defects and fertility problems in mice whose cages have been in contact with them, according to Patricia Hunt at Washington State University in Pullman. The quaternary ammonium compounds ADBAC (n-alkyl dimethyl benzyl ammonium chloride) and DDAC (didecyl dimethyl ammonium chloride) were identified after an exhaustive search for what was causing a massive drop-off in mouse fertility after Hunt moved her research animals to Pullman from Case Western Reserve Medical School in Cleveland, Ohio, in 2005. The chemicals were in the disinfectant Virex used in the facility. It is Hunt's second accidental foray into toxicology. In 2003 she linked a rash of mysterious egg defects in her research animals to bisphenol A, a chemical that began leaching from plastic water bottles after a high-pH floor detergent was mistakenly used to clean them. Hunt, who studies mammalian egg development, announced her latest results at the Society for the Study of Reproduction meeting in Kona, Hawaii, last month.

That means that she is getting to our young people and poisoning their minds
with her scientific sounding gibberish. I would really welcome a detailed
rebuttal to this video being posted at DIGG and at Youtube or wherever the
Snowshoe Films video has been posted. They also have Doug Rokke anti-DU
videos as well. No idea why they have decided to make their mark on the
world by being anti-DU crusaders.

I agree, and just want to emphasize, ALARA makes sense (or at least is a
fair compromise for public policy purposes, since we can't really expect most of
our politicians to really understand risk assessment) only so long as we
don't forget the importance of the "R." REASONABLY achievable does not equal
technologically achievable (at any cost).

BP uses ALARP in their corporate HSSE documentation (overall for all aspects of HSSE guidance not just RAD) as in the last A becomes P for PRACTICAL and the speak of a concept of balance to include costs and benefits.

Hmmmm:
Given their safety record here in their Houston/Deer Park refinery, I would
not hold BP up as much of an example....
But the correct application of ALARA (according to ICRP recommendations
1990) is "(doses)should be kept as low as reasonably achievable, economic
and social factors being taken into account....."
The use of "Practical" seems to be just a change for the sake of "being
different"

Doug
