Explaining the Possible Reasons of Rhythmic and Spоradic Changes in the Rate of Beta Decays

In a number of experiments, when detecting particles emitted in beta decays, periodic oscillations of
count rate with an amplitude up to tenths of a percent and short bursts vastly exceeding the usual
count rate are found. At the same time, several experiments did not detect any differences from the
“normal” course of beta decays greater than 0.01%. The article shows that the inconsistency of the
experimental results is due to different measurement technique. The assumption is made of the
possible participation in the beta decay processes of cosmic slow neutrinos, which makes it possible
to explain in a comprehensive manner not only periodic and sporadic changes in the beta decay rate,
but also a number of other incomprehensible phenomena associated with beta radioactivity. On the
basis of the experiments carried out, an estimate is made of the flux density of slow cosmic neutrinos.
