Surveys of radioactive contamination were performed for imported foodstuffs in 2003. The following samples among imported foodstuffs were selected from markets and Korea Food and Drug Administration(KFDA); the imported samples from country associated with the Chernobyl nuclear accident, the samples produced around the nuclear power plants or nuclear tests, the foodstuffs reported as radioacitive contamination materials in foreign country. After pretreatments such as drying and homogenization, samples were analyzed. The $^{137}Cs$ radionuclide was only measured among the regulation radionuclides($^{137}Cs,\;^{134}Cs,\;^{131}I$) of food code. All foodstuffs except Inonotus Obliquus(Chaga mushooms) are less than 17.0 Bq/kg or below the minimum detectable activity(MDA). The activity concentrations of Chaga mushrooms from Russia ranged up to 131.25 Bq/ltg which is almost 35 % of the maximum permitted level of food code. The fraction of imported foodstuffs having meaningful radioactivity is small, however, the radioactive contamination survey of imported foodstuffs is still needed.

최근 원자력발전소주변 환경방사선에 대한 국민적 관심이 고조되고 있으나 환경중 방사능 축적에 대한 허용기준치가 정립되어 있지 않아 효과적인 대 국민 홍보에 한계가 있다. 따라서 원전 주변 주민의 생활습관을 파악하여 섭취량을 품종별로 분류하여, 조사, 분석함으로서 환경시료중 방사능 허용농도를 설정함으로서 원자력발전소 주변 환경방사능 농도를 설정된 허용농도와 비교하여 원전의 안전성에 대한 대 국민 이해 및 신뢰 회복에 이바지 하고자 한다. 또한 최대허용농도를 기준으로 삼던 기존의 방식이 퇴색하고 ALI［l］를 이용한 국내 실정에 맞는 식품 중 허용농도 설정의 필요성이 대두되고 있는 현 실정을 감안하여 ALI를 이용하여 식품 중 최대허용농도를 설정하고자 한다.

The purpose of this study was to examine the impact of the Fukushima nuclear power plant accident of Japan in 2011 on kindergarten parents' perception about irradiated foods and radioactive-contaminated foods. This study analysed the 178 questionnaire forms out of 205 parents of 'K' and 'M' kindergarten in the region of 'J' city. The findings of the study indicated that the Japanese nuclear power plant accident exerted an influence on anxious of kindergarten parents about irradiated foods and radioactive-contaminated foods. In conclusion, The full-fledged publicity and parent education are required to improve the perception and understanding of kindergarten parents about irradiated foods and the differences between it and radioactive-contaminated foods.

After the Fukushima nuclear accident, interest in radioactive intake through food has increased significantly. Radioactivity is colorless, tasteless, and odorless, making it very difficult to determine whether it is contaminated, and it is important to check the radioactive safety of food as it can lead to long-term exposure during intake and absorption. In particular, children have more active metabolic activities than adults, so the risk of absorption after intake is judged to be high, so stricter acceptance standards are applied. Nevertheless, there is not little anxiety about radioactive contamination. Therefore, this study aims to confirm radioactive safety by analyzing gamma nuclides of milk with the highest intake in infancy in all ages based on 2021 national nutrition statistics. Samples were selected from 10 domestic milk types made of 100% domestic raw materials through K-MILK certification. Sample analysis was conducted according to the radioactive test method of 'Standards and Specifications for Food'. As a result of the analysis, all 10 types of milk nuclides ¹³¹I, ¹³⁴Cs, ¹³⁷Cs were determined to be less than MDA(Minimum Detectable Activity) and were not detected. Therefore, it is judged that there is no contamination of ¹³¹I, ¹³⁴Cs, and ¹³⁷Cs nuclides in milk made from domestic raw materials, and when the annual intake dose of milk was conservatively evaluated using the measured MDA value, the radioactive safety of domestic milk was confirmed at 0.001% of the annual effective dose limit.

Background: The objective of this study was to investigate Korean people's awareness about impact of the Fukushima nuclear power plant accident in Japan and radioactive contamination caused by it. Materials and Methods: The respondents of the survey were 600 adults who resided in the Seoul metropolitan area. Results and discussion: The survey results show that the majority of respondents were concerned about impact of radiation leakage that might have an effect on our environment. They were worried about radioactive contamination of foodstuffs, particularly fishery products and preferred to acquire information through TV(49.8%) or the Internet(31.3%). Meanwhile, respondents mentioned that the information on the Fukushima nuclear accident and radioactive contamination had not been sufficient and they didn't know well about the follow-up measures of the government on the accident. Most respondents answered that information on radioactive contamination levels and safety of foods and environment was most needed. Conclusion: The results of this study could be useful to enhance awareness on radioactivity and improve risk communication on nuclear power plant accidents.

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.
