Abstract

We show that cavitation of a solution of thorium-228 in water induces
its transformation at a rate 10^4 times faster than the natural
radioactive decay would do. This result agrees with the alteration of
the secular equilibrium of thorium-234 obtained by a Russian team via
explosion of titanium foils in water and solutions. These evidences
further support some preliminary clues for the possibility of
piezonuclear reactions (namely nuclear reactions induced by pressure
waves) obtained in the last ten years.

Wow!
And it has always be my suspicion that also simple *friction* between
some materials causes nuclear reactions.

... they considered their result "not positive".

Activation energies as low as they propose, would have left the Earth
with NO thorium, since it has undergone many cataclysms since
formation. Yet we have thorium.

That one is where the train leaves the tracks,
as far as I'm concerned. Maybe I could believe
accelerated decay, but decay without gamma
emission is a bit too much.

Well, if it is mechanically initiated (hah!!!), then maybe the gamma
was directed at the experimenters brain cells, rather than at the
detectors?

I think you left out a word or three there, but If you're referring
to the claim that transmutation happens without gamma emissions, ISTM
there's three possibilities. Either there's a previously unknown decay
channel that doesn't generate gammas, the gammas are indeed emitted
but are absorbed by the liquid environment, or the authors are full of
crap.

With regard to the known decay paths of all radionuclides,
about what % of these of nuclear transmutation reactions
do not emit gamma rays?

Any possibility of Th fission, given the pressures involved in cavitation?

"Occasionally it decays by the unusual route of cluster decay,
emitting a
nucleus of oxygen-20."

Cluster decay of Th-228 sounds very similar to fission. However, one
can Google for:

ANOMALIES OF NUCLEAR CRITICALITY, REVISION 6
E. D. Clayton
Edited by
A. W. Prichard, B. M. Durst, D. G. Erickson and R. J. Puigh
February 2010
Pacific Northwest National Laboratory

They says that Th-228 is incapable of either slow or fast neutron
chain reaction. However, it is known that fission can be induced by
high energy processes in practically everything. E.g. in 1934 Leo
Slizard reported neutron emmision from beryllium induced by hard xrays.

Dunno.

Of the so called pure alpha or beta emitters how pure are they really?

Say Po210 (alpha) or Sr90/Y90 (both nominally pure beta though Y90 has a
weak gamma) - you would think that after a quantum tunnelling escape the
nucleus would always have to rearrange itself to reach a new minimum
energy state with the emission of some electromagnetic energy.

However Po210 the alpha production rate according to radioisotope tables
is something like 99.999% with only 1:10^5 causing a gamma emission.

Is this strictly true or does emission of a photon occur at an energy
that is not easily detected?

Turning it round is there something special about nuclear species that
are pure beta or pure alpha emitters.

Martin Brown

It would be a lot easier to believe that cavitation can produce pits in
CR39 detector sheets that could be mistaken for alpha particle tracks.

Abstract
We show that cavitation of a solution of thorium-228 in water induces
its transformation at a rate 10^4 times faster than the natural
radioactive decay would do. [snippage]

Thorium-228 has a half-life of 1.9116 years = 60325508 seconds.

If the authors claim about this short lived isotope is true, ultrasonication
would reduce its half life to 6033 seconds.

The fact that a short lived isotope of thorium was claimed, may have been
missed by responders.

Given the short half life, activation energy for nuclear processes would be
smaller than expected.

Whoops, there's more, see:

"Occasionally it decays by the unusual route of cluster decay, emitting a

It is plausible that ultrasonication of Th-228 excites low activation
cluster decay.

This may be a way to accelerate the decay of short lived isotopes. But any
serious work would need to be done by robots. The risks of volcanic
eruptions of highly radioactive solutions are obvious.

Depends what is happening in the cavitation bubble.
The temps there are high enough to emit soft x-rays

It isn't true. The signal equals the noise.

Then bombarding it with x-rays should elicit decay. Since that
doesn't happen, it is just "cold fission".
