Abstract
The light yield in CaMoO4 scintillating crystals irradiated with α particles and γ rays from 241Am and 137Cs radioactive isotopes, respectively, have been measured. It is shown that the light yield in this crystal for γ rays, measured in the wavelength range of 400–700 nm at room temperature (22°C), is ∼3000 photons/MeV, and the ratio α/β is ∼0.25.
