We report the observation of multi-exponential scintillation light emission from a CaMoO4 crystal with slow and fast components after both α-particles or γ-quanta irradiation. The slow components with decay times of ∼5 and ∼15μs produce the main contribution to the light yield. Whereas the fast components with ∼10–50ns decay times observed for the first time with such a crystal at room temperature contribute <1% to the crystal total light yield.
