The behavior of poly(vinylpyridine) with a gamma ray source has been studied. In the present work, samples were irra- diated in air with a 60Co or 137Cs gamma cell source (absorbed dose 10 Gy to 14400 kGy). All tested samples show well defined ESR signals whose amplitude increases with time. The behavior at room temperature and dose−effect relationships were investi- gated.
