Researches of alpha and beta radioactivity at long-term observations

TL;DR

This study reports long-term observations of alpha and beta radioactivity, revealing annual and monthly rhythmic variations in beta decay count rates, with no detectable alpha decay rhythm, and compares these findings with other research.

Contribution

It provides a 13-year continuous dataset of radioactivity measurements, identifying periodic variations in beta decay rates and analyzing their potential significance.

Findings

Rhythmic changes in beta decay count rates with annual and monthly periods.

No rhythmic variations detected in alpha decay count rates.

Comparison and analysis of results with other researchers' findings.

Abstract

The part of results obtained on multichannel installation created for researches of various processes, including alpha and beta decays, in a combination to recording of environment parameters, is represented. The installation works more than 13 years practically continuously. At the count rate measurements of the Co-60 and Sr-90 Y-90 beta sources the rhythmic changes with amplitude 0.3 % from average magnitude and period 1 year, and up to 0.02 % with period about one month are detected. Count rate rhythmic changes of alpha sources Pu-239 are not detected. The results obtained by us are compared to similar results of other researchers. The argumentation of critics is analyzed.
