In this paper, we show that low energy gamma rays down to few keV can be detected with CsI(Tl) crystal detector. A clear peak at 6 keV from a radioactive source is observed. In addition, we also show that alpha particles and gamma rays can be separated greater than 3 σ level down to 50 keV region using the different time characteristics of the crystal for both signals. With further background study, we should be able to determine CsI(Tl) be a good candidate detector in search for weakly interacting massive particles (WIMPs).
