Abstract

This study explores the impact of solar flare events on radioactive materials, focusing in particular on the thorium decay chain. Previous research has indicated that gamma emitters are affected by solar flares, resulting in count-rate dips. In this study, we present, for the first time, concurrent gamma and beta count-rate measurements from a thorium radioactive source, revealing multiple dips in the count rate. Based on a consideration of the temporal relationship between beta and gamma emissions, we propose that the response to solar events originates primarily from beta emissions. To investigate this phenomenon further, we employ plastic scintillator beta detectors, enabling the examination of various radioactive sources and the study of neutrino interactions and their impact on decay rates. This experimental approach offers an opportunity to expand our knowledge of particle interactions and provides insights into the interplay between solar flares, neutrino flux, and the behavior of radioactive materials.

Key words: radioactive decay, thorium, gamma emission, beta emission, count-rate measurement, plastic scintillator, neutrino interaction
