Abstract

Radioactivity in foodstuffs was surveyed for reference in amending regulation on the maximum permitted levels of radioactive contamination of foodstuffs. Most domestic and imported (?) foodstuffs were sampled, some domestic items collected around nuclear power plants to compare site-specific contamination. The collected samples were dried and ashed. Radioactivity in foodstuffs was measured using HPGe gamma spectrometer, Cs-137 activity ranged from 0.025-0.053, 0.045-0.500, 0.062-0.105, 0.025-1.151, 0.021-0.145 and 0.046-0.155 Bq/kg-fresh in cereals, pulses, mot vegetables (potato), ginsengs, meat, and marine products, respectively, with imported dried ginseng showing the highest radioactivity, Results reveal radioactivity in foodstuffs collected in 2002 is far below the maximum permitted levels of 370 Bq/kg. No significant differences were observed in radioactivity among sampling sites and between domestic and imported foodstuffs.

본 연구는 국내에서 생산된 식품과 수입식품에 대한 방사능 오염실태를 조사하고 그 결과를 바탕으로 식품에 대한 방사능 오염의 기준 및 규격 설정을 위한 기초자료 생산을 목표로 수행되었다. 조사 대상시료는 국민식생활에 근거하여 곡류, 두류, 근채류, 인삼류, 어패류, 육류 등으로 선정하였다. 국내 생산된 식품 중에서 쌀, 대두, 감자, 쇠고기의 경우는 지역별 오염실태 차이를 파악하기 위해 국내 원자력발전소 주변지역에서 시료를 구입하였다. 모든 시료는 건조하여 회화시킨 후 사용하였으며, 방사능 농도는 감마핵종분석기를 이용하여 측정하였다. 인공방사능인 Cs-137의 방사능농도는 곡류의 경우는 0.025-0.053 Bq/kg-fresh, 두류는 0.045-0.500Bq/kg-fresh, 근채류(감자)는 0.062-0.105 Bq/kg-fresh, 인삼류는 0.025-1.151 Bq/kg-fresh, 육류(쇠고기)는 0.021-0.145 Bq/kg-fresh, 어패류는 0.046-0.155 Bq/kg-fresh의 범위를 나타냈으며, 다. 본 조사 결과 2002년도에 채취된 국내에서 생산된 식품 중 Cs-137의 농도는 지역별로 큰 차이를 나타내지 않았으며, 식품 중의 방사능 잠정허용기준치인 370Bq/kg에 훨씬 못 미치는 무시할 정도의 값으로 나타났다. 또한, 수입식품 중 2002년도에 채취된 시료인 쌀(태국산), 밀(미국산), 대두(러시아산), 홍합(뉴질랜드산), 수삼(중국산), 쇠고기(호주산, 미국산)의 경우도 국내산과 큰 차이를 나타내지 않았다. 그러나 조사항목 중 중국에서 수입된 인삼(건삼) 중의 방사능 농도가 다른 식품시료에 비해 상대적으로 높다는 것은 특이할 만한 사항이다.
