N2 - Solar neutrino detection is known to be a very challenging task, due to
the minuscule absorption cross-section and mass of the neutrino. One
research showed that relative large solar-flares affected the
decay-rates of Mn-54 in December 2006. Since most the radiation emitted
during a solar flare are blocked before reaching the earth surface, it
should be assumed that such decay-rate changes could be due to neutrino
flux increase from the sun, in which only neutrinos can penetrate the
radionuclide. This study employs the Rn-222 radioactive source for the
task of solar flare detection, based on the prediction that it will
provide a stable gamma ray counting rate. In order to ascertain counting
stability, three counting systems were constructed to track the
count-rate changes. The signal processing approach was applied in the
raw data analysis. The Rn-222 count-rate measurements showed several
radiation counting dips, indicating that the radioactive nuclide can be
affected by order of magnitude neutrino flux change from the sun. We
conclude that using the cooled Radon source obtained the clearest
responses, and therefore this is the preferable system for detecting
neutrino emissions from a controlled source.
