A Method of Short-Term Forecasting of Ultradian and Infradian Rhythms Based on the Recording of Fluctuations in the Rates of Radioactive Decay of Potassium-40

Abstract

Simultaneous observations of radioactivity fluctuations from the natural isotope ⁴⁰K were carried out in Moscow and Ulyanovsk. It was found that the changes in the counting rate from sources in these geographical points were not simultaneous, but were synchronized according to local solar time. Based on this observation and considering that radioactivity fluctuations correlated with body temperature rhythms, a method for short-term prediction of ultradian rhythms of animal activity has been developed and confirmed. An analysis of the consistency of the dynamics of the intensity of decay fluctuations and daily growth rates of an L-929 cell culture was also carried out. It was found that the highest correlation coefficient was recorded when the indicator of proliferative activity of the culture was compared with the intensity of decay fluctuations taken over the previous day. Thus, based on data on fluctuations in the radioactive decay of ⁴⁰K, which are an indicator of the biotropic factor of the environment, it is possible to make short-term forecasts of ultradian and infradian biological rhythms.
