Abstract Using the EPR technique, a series of irradiated silicate, phosphate and alumophosphate cadmium-containing glasses with an admixture of copper and halogens have been investigated. We have observed the EPR spectrum due to Cd +, determined the hfs constant for Cd + as a function of glass composition, detected a change in the structural position of Cd + with varying Al 2O 3 concentration. It has been found that the glass composition affects the degree of distortion of the PO 4 tetrahedron which manifests itself in a change in the hfs constant for the PO 2− 3 radical. A new phosphorus radical with the parameters A 1 = 312 G and g 1 = 2.0034 has been observed.
