Fluctuations in Nuclear Decay Rates and Solar Activity

For many years Professor Simon Shnoll and other scientists at the Russian Biophysics Laboratory at Pushchino has reported that some nuclear decay rates are not constant. They found there are variations in histograms of nuclear decay rates sampled at regular short intervals. The histogram shapes tend to become similar again after certain intervals, notably a day, a year and a month. These intervals show that cosmic factors are important in affecting nuclear decay.

In the mid 1990s I received samples of time series data for Plutonium decay from these scientists and found that cycles of 3 and 6 minutes were also present. These cycles are both of unstable phase, with incoherence beyond about 20 cycles. Dr Natalia Udaltsova confirmed that these two periods were present throughout decades of stored data. I had previously predicted such periods as being associated with inner solar system activity related to both Planetary spacings and solar activity.

More recently, several reports have shown that other nuclear decay rates fluctuate on an annual basis and the distance of the Sun has been suggested as a cause along with fluctuations in Solar flare activity.

Unexplained periodic fluctuations in the decay rates of Si-32 and Ra-226 have been reported by groups at Brookhaven National Laboratory (Si-32), and at the Physikalisch-Technische-Bundesandstalt in Germany (Ra-226). We show from an analysis of the raw data in these experiments that the observed fluctuations are strongly correlated in time, not only with each other, but also with the distance between the Earth and the Sun. Some implications of these results are also discussed, including the suggestion that discrepancies in published half-life determinations for these and other nuclides may be attributable in part to differences in solar activity during the course of the various experiments, or to seasonal variations in fundamental constants.

Recently, Jenkins, et al. have reported the detection of correlations between fluctuations in nuclear decay rates and Earth-Sun distance, which suggest that nuclear decay rates can be affected by solar activity. In this paper, we report the detection of a significant decrease in the decay of 54Mn during the solar flare of 13 December 2006, whose x-rays were first recorded at 02:37 UT (21:37 EST on 12 December). Our detector was a 1 uCi sample of 54Mn, whose decay rate exhibited a dip coincident in time with spikes in both the x-ray and proton fluxes recorded by the GOES-10 and 11 satellites. A secondary peak in the x-ray and proton fluxes on 17 December at 12:40 EST was also accompanied by a coincident dip in the 54Mn decay rate. These observations support the claim by Jenkins, et al. that nuclear decay rates vary with Earth-Sun distance.

In my view these various findings are most easily understood when the wave structure of all phenomena is always kept in mind. If particles are understood as spherical standing wave structures and atoms as conglomerates of these, then it is easy to understand that the stability of marginally stable atoms is likely to be affected by other waves, particularly very energetic ones. In this regard the WSM (Wave Structure of Matter) is a useful basis for making future progress.

About Ray Tomes

Ray's career was in computer software development including system software design, economic modeling, investments. He spent 15 years full time on cycles research and has spoken on cycles and related topics at conferences and seminars around the world. He retired at age 42 to study cycles full time and work out “The Formula for the Universe” and as a result developed the Harmonics Theory as an explanation for observed patterns of cycles and structure of the Universe. His current project is the development of CATS (Cycles Analysis & Time Series) software, and collecting and organizing large quantities of time series data and analyzing this data to test and confirm Dewey's findings in an organized way. Interested in all aspects of cycles especially climate change and causes.
