Method for short-term prediction of ultradian and infradian rhythms based on the registration of fluctuations in the rates of radioactive decay of potassium-40

Abstract

Observations of fluctuations in the rates of radioactive decay of potassium-40, a naturally occuring radioactive isotope of potassium, were made simultaneously in Moscow and Ulyanovsk. It was shown that variations of the count rates from sources in these geographic areas did not happen at the same time but were synchronized with local solar time. Based on this observation and taking into account that fluctuations in the rates of radioactive decay correlate with body temperature rhythms, a method for short-term prediction of ultradian rhythms of animal activity was developed and validated. The correlation analysis was conducted to see the relationship between the dynamics of the intensity of radioactive decay rates variability and the daily growth rates of the cell culture L-929. It was found that the maximum correlation coefficient can be observed after comparison of the indicator of the proliferative activity of the culture with the value of the intensity of radioactive decay rates variability as it was the day before the comparison. Thus, based on the data on fluctuations in the rates of radioactive decay of potassium-40, which is an indicator of the biotropic factor of the environment, it is possible to make short-term forecasts of ultradian and infradian biological rhythms.
