Samples of H2O and D2O and solutions of H2O2, HClO4, HF, etc., in light and heavy water, were tritiated with T2O to activities of from 0.1 to 1 c/ml.The paramagnetic resonance spectra recorded at liquid nitrogen temperature and interpreted as representing H (D) atoms and OH (OD), HO2 (DO2) free radicals were compared with those induced under analogous conditions by Co60 γ-rays.The lower radical yields observed in the present work have been ascribed to the difference in linear energy transfer between Tβ-particles and more penetrating radiations.
