EPR Measurements of Radiation Immunization in Poly (methyl Methacrylate) by Organic Additives


Electron paramagnetic resonance techniques were used to compare the relative radiation immunity against free-radical formation given to poly(methyl methacrylate) by the addition of various protective agents at low concentration (5%). Under irradiation by X rays and pile gamma rays, it was found that the degree of protection afforded varied rapidly with the total radiation dose.
