【Abstract】 Electron spin resonance (ESR) spectra of several organic materials, includingcotton, polyester fibres and hair irradiated by gamma-rays, have been measured.The stability of free radicals resulting from gamma rays irradiation in these mate-rials, dose responses and zero dose readings have been studied. Besides, the feasi-bility of applying ESR technique to evaluation of nuclear accident radiation dosehas been discussed.更多还原
