Gamma dose effects on the electron paramagnetic resonance (EPR) structure of free radical species in polymethylmethacrylate (PMMA) were investigated. Cubic samples of 30 mm/sup 3/ volume were irradiated with Co/sup 60/ at 1.17 r/hr. The EPR spectra were measured using an apparatus having 100-kc modulation and a 9300-Mc microwave system. Derivative curves of the spectra were obtained using a phase detector. Spectral-change data are presented in graphical form. (L.N.N.)
