브라질중부지구에 위치한 고이아스주의 주도 고이아니아시에서 1987년 9월 23일 방사성동위원소 세슘137에 의한 방사선피폭오염사고가 발생했다. 이 사고는 원자력 평화이용의 역사에서 소련의 체르노빌 사고이래 최악의 방사선피폭 오염사고로 기록될 불상사였다. 오염경위 및 사건의 원인을 보면, 방사선관리가 소홀했었음이 판명되어 새삼 원자력 및 방사선 안전확보의 중요성을 일깨워주는 사고였다.

The purpose of the study is to evaluate the effect on medical application and convergence for the efficient disaster responses in the massive radiological events by comparison of two types of survey-meters(hand held survey-meter and transportable portal monitor). In the simulated radiation disaster drill, twelve participants randomly wore a personal protective equipments (PPE) with twelve check source. We measured participants to detect five real radioactive sources of the twelve check sources, using two types of survey meters. The primary outcome was the measuring time. The secondary outcome was the sensitivity and specificity of the detection of the real radioactive source. The average time by the hand held survey meter was 231.9 ± 116.6 seconds, and the time by transportable portal monitor was statistically shorter 8.690 ± 1.667 seconds. There was no difference in the sensitivity and specificity between two survey meters. The transportable portal monitor survey meter was considered to have medical application and play an important role in radiological disasters.

The radiation sources leaked from large-scale radiation leak accident like the Hukushima nuclear power plant accident or nuclear explosions can cause to the very large damage for us. So that the damage can be minimized, we have being developed a detector that can providing information about the location of the source to remove dangerous substances quickly than the conventional single detector. In this paper, we designed the shielding and collimator for the development of the Stereo Radiation detector in order to detect contaminants using MCNP Code. And we analyzed the results that is detected from the discretionary position of the radiation source. The results of this paper will be used as the basis for designing efficient structure for the radiation detectors.

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.
