Reduction of the radiation in radioactive substances

The radioactivity reduction of a system containing Ni-63 radioactive nuclei after an appropriate ultrasound treatment in an apparatus designed on purpose is reported. The application of ultrasounds for 200 s resulted in the partial disappearance of about 13% of the radioactive Ni-63 nuclei and the appearance of nonradioactive elements. The formation of new elements, not belonging to the decay chain of Nickel-63, is a strong issue where strong nuclear reactions transform Nickel into different elements rather than the usual weak interaction, responsible for the decay, which is accelerated. This way, the time necessary to halve the intensity is shortened by about 20 years, without altering the Ni-63 decay constant, which is 146.002 +/-.16 years. Two cases producing similar effects in other radioactive systems after ultrasound treatment are described in the literature and support this finding, which is not forecast by the commonly accepted theories. A theory able to explain these and other results is also reported.
