Thanks to Curbina for mentioning in a different thread this paper, published on ResearchGate in November 2019, which I had not seen before.
Title: “The astonishing 63Ni radioactivity reduction in radioactive wastes by means of ultrasounds application”
Authors: Alberto Rosada, F. Cardone, Pasquale Avino.
Nowadays, the radioactive wastes production is certainly one of the main issues along with their storage. The most interesting way to treat them would certainly be the radioactivity reduction. In this paper we show that the ⁶³Ni radioactivity reduction by ultrasounds is not a violation of the exponential decay law but can be explained by the Deformed Space–Time theory. The cavitation procedure under the DST conditions achieves a radioactivity decrease around 14% in 200 s. Comparing these results with the theoretical ones obtained by the decay law, we earn more than 20 years in the ⁶³Ni radioactivity decrease. For confirming the data, ICP-MS measurements were performed on cavitated and no-cavitated samples: once again, the 14%-difference (with CV 5%) was obtained from the analyses of both samples. Even if the data are not definitive, the new idea is that a radioactive substance can be “normalized” by its transformation into a normal stable one without radiation emission overcoming the traditional approaches (dilution, inertization, radioactive transmutation with fast neutron irradiation) and avoiding the use of large deposits or big reactors. Our results may be considered as starting point to pave the way to new methods to treat useless harmful radioactive substances from nuclear or medicine industry.
Here is Curbina’s comment on the paper:
“As the reality of radioactive waste remediation by means of cavitation or HHO treatment is taking long to be accepted, I think increasing awareness of this technological solution to the biggest issue with conventional fission is something we should all embrace as a primary task. Mainstream Acceptance of this should also pave the way to widespread acceptance of LENR as a reality.”
