The Ci2O4 impurity has been found to be very effective in stabiUzing a phosphorus oxyradical produced by y-irradiation at room temperature in KH2PO4 and NH4H2PO4 crystals. A similar radical species can be observed in pure Ba(H2P04)2 crystals y-irradiated at room temperature. The observed principal values of the g-factor and the hyperfine splitting indicate that this radical species could be the [PO5]2 or [OjPOO]2-.
