摘要：

太阳中微子探测是一项非常具有挑战性的任务，因为中微子的吸收截面和质量都很小。一项研究表明，2006年12月相对较大的太阳耀斑影响了Mn-54的衰变率。由于在太阳耀斑期间发射的大部分辐射在到达地球表面之前被阻挡，因此应该假设这种衰变率的变化可能是由于来自太阳的中微子通量增加，其中只有中微子可以穿透放射性核素。本研究使用Rn-222放射源进行太阳耀斑探测，其依据是它将提供稳定的伽马射线计数率。为了确定计数稳定性，构建了三个计数系统来跟踪计数率的变化。Rn-222的计数率测量显示了几个辐射计数下降，表明放射性核素可以受到来自太阳的中微子通量变化的影响。我们的结论是，使用冷却的氡源获得了最清晰的响应，因此，这是一个较好的系统，用于检测中微子发射的受控源。

英文摘要：

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 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.
