Low temperature detectors have been attractive tools in many aspects of science. Since their energy resolution was achieved beyond the theoretical limits of semiconductor detectors, these detectors have been successfully adapted in the radiation detection and measurement used for nuclear and astroparticle physics. In the presentation, basic principle of the cryogenic particle detection is introduced and compared with conventional detector technologies. Recent progress on crystal detector development to monitor neutrinoless double beta decay signals is presented. In addition, for the detection and identification alpha emitting radionuclides, a cryogenic 4p detection method is discussed with their remarkable performances in energy resolution and detection efficiency.
