Energy resolution, non-proportionality in the scintillation response, α/β ratio, pulse shape for γ rays and α particles were studied with CdWO4 crystal scintillators. Some indication for a difference in the emission spectra for γ rays and α particles was observed. No dependence of CdWO4 pulse shape on emission spectrum wavelengths under laser, α particles and γ ray excitation was observed. Dependence of scintillation pulse shape for γ quanta and α particles and pulse-shape discrimination ability on temperature was measured in the range of 0–24 °C.
