Searches for weakly interacting massive particles (WIMP) can be based on the detection of nuclear recoil energy in CsI(Tl) crystals. We demonstrate that low-energy gamma rays down to a few keV are detected with CsI(Tl) crystal detector. A clear peak at 6 keV is observed using an X-ray source. Good energy resolution and linearity have been achieved down to the X-ray region. In addition, we also show that alpha particles and gamma rays can be clearly separated using the different time characteristics of the crystal.
