장과류의 방사능 안전성 확보를 위해 2016년부터 2018년까지 경기도 내 유통 중인 장과류 및 가공식품 15품목 258건을 수거하여 방사능 오염을 분석하였다. 방사능 분석은 게르마늄 감마핵종 분석기를 이용하였으며, 인공 방사성 물질인 요오드(131I)와 세슘(134Cs, 137Cs)을 분석하였다. 모든 제품에서 131I와 134Cs은 MDA (Minimum Detectable Activity)값 이상으로 검출되지 않았고, 39건에서 0.69-808.90 Bq/kg 범위로 137Cs이 검출되었다. 국내산 제품 6건은 0.70- 3.29 Bq/kg 범위에서 검출되었지만, 원재료는 모두 수입산 이었다. 수입산 제품 33건은 0.69-808.90 Bq/kg 방사능 농도를 나타내었으며, 폴란드산 블루베리 분말 제품 1건(808.90 Bq/kg) 및 링곤베리 분말 제품 2건(103.93, 188.46 Bq/kg)은 국내 방사성 세슘의 허용 기준을 초과하였다. 이러한 결과는 식품 안전 확보를 위해 수입산 장과류와 장과류 가공식품에 대한 방사능 검사 강화와 함께 수입 과정에서 더 철저한 관리가 필요한 것으로 판단된다.

To ensure food safety of berries from radioactive contamination, radioactivity monitoring was conducted with a total 258 samples of the berries and processed berry products distributed in Gyeonggi-do, South Korea, from 2016 to 2018. The concentration of artificial radionuclides, 131I, 134Cs and 137Cs, was analyzed using gamma-ray spectrometry. 131I and 134Cs were not detected above the MDA (Minimum Detectable Activity) value from any of the samples. However, the range of radioactivity concentration of 137Cs was 0.69-808.90 Bq/kg in 39 cases of berries. 137Cs was detected at 0.70-3.29 Bq/kg from 6 cases of domestic berries, which were manufactured from imported raw materials. Among 33 cases of imported berries, 137Cs was detected at 0.69-808.90 Bq/kg. The concentrations of 137Cs in 1 case of blueberry powder product (808.90 Bq/kg) and 2 cases of lingonberry powder products (103.93, 188.46 Bq/kg) exceed domestic maximum radioactivity limits, and these were detected in the berries from Poland. These results suggest that monitoring system for imported berries and processed berry products should be continuously intensified to secure food safety.
