ESR spectroscopy에 의한 방사선 조사 건조향신료의 조사여부의 정확한 판별에 필요한 기초자료를 얻고자 방사선 조사 유래의 cellulose radical에 대한 parameter를 분석하였다. 건조향신료 분말 4종(고추, 마늘, 양파, 후추)에 대하여 0, 1, 5, 10 kGy의 감마선을 조사한 후 ESR signal을 분석하였다. 방사선 조사된 4종의 건조향신료는 모두 방사선 조사 유래의 triplet signal인 cellulo

Gamma-ray treatment was used to exterminate nematodes, which were harmful to agriculture. When gamma-ray at the dose range of 5～75 kGy was irrdaidated, nematodes were reduced by 40～50%. When irradiated over 30 kGy, almost nematodes were non-mobile and fluorochromatic reactions showed that 60～80% of nematodes with non-mobility died after irradiation. The results of electron spin resonance spectroscopy suggested that radicals generated by radiolysis could damage to nematodes.
