We present a detailed study of the radiation damage centres produced in Cs₂NaYF₆ upon X-irradiation at 10 and 300 K. The defects were investigated using magnetooptical and magnetic resonance spectroscopy. As hole trap centres at low temperatures V_K centres and H_A-type centres were identified by EPR and their optical transitions by optical absorption and the magnetic circular dichroism of the absorption. As electron trap centres F centres were investigated in detail by ENDOR.
