In this project, under the server-client environment, GIS for the radiological emergency and control system of the vehicles for the environmental radioactivity monitoring was complete. This system is able to display environmental radioactivity data and vehicle's locations through wireless network on real time. Furthermore, it supports not only static analysis function with the collected data regarding nuclear type, collecting time period and vehicle's location but also a documents printing out function.

국가 환경방사선/능 자동감시망과 원전주변의 환경방사선/능 감시를 통해서 연속적으로 측정 기록된 대량의 환경방사선/능 정보들이 효과적으로 활용되고 있지 않는 상황에서 환경방사선/능 정보에 내재되어 있는 공간정보 속성들을 정량적으로 해석하고 시공간적으로 예측할 필요성이 있다. 지구통계기법을 활용하면 환경방사선 감시설비가 비록 설치되어 있지 않은 지점일지라도 환경방사선/능 정보에 대한 예측이 가능하므로 향후 추가적인 감시기의 설치와 시료분석에 소요되는 시간과 비용을 절감할 수 있다. 본 연구에서는 고리, 월성, 영광, 울진 원자력발전소와 대전 한국원자력연구소 등 국내 원자력이용시설 주변 토양중의 환경방사능 분포를 감마동위원소인 $^{137}Cs$과 $^{40}K$을 중심으로 파악하였다.

원전의 방사능 누출은 물론, 전국의 환경 방사선이나 기상 등을 수시로 종합 감시하여 즉각적으로 대응하는 방사능 방재 전산망이 본격 가동되었다. 과학기술처는 7월 31일 과천 청사 방사선 비상대책실에서 원전 사고 등 비상시에 방사능 누출 현황 등을 컴퓨터 화면으로 한눈에 보고 대응책을 마련할 수 있는 방사능방재대책 기술지원전산망 가동식을 가졌다. 이 전산망은 $\ulcorner$방사선 영향 평가 및 예측 전산화 시스템(CARE)$\lrcorner$을 중심으로 서울 등 전국 20개 지역의 환경방사선량을 표시해주는 환경방사능 감시망과 기상자료 수집망이 하나로 연결된 컴퓨터 통신망이다. 이의 운영 현황을 들어본다.

The objective of this research was to assess the reliability of data and to improve nuclear analytical techniques concerning the Domestic Radioactivity Intercomparison program for environmental radioactivity monitoring of Jeju from 1998 to 2006. Gross beta for filter papers and water samples was determined, and gamma nuclides for natural and artificial nuclides in soil and water samples were analyzed. The gross beta activity of all samples except for the water samples of 1998 and 1999 showed a good agreement within the confidence intervals. In gamma nuclides, $^{40}K$ and $^{137}Cs$ of soil samples and most nuclides in the water samples, with the exception of several nuclides, were evaluated to be reliable. Based on these results, it is considered that a reliable method for the analysis and monitoring of environmental radioactivity were established, which may play an important role in case of emergency radiation accident.

An estimate of a change in radioactivity's circumstances around the nuclear power plant is validated with the results of the radioactivity measurements are compared. In this study, to further enhance the reliability of the results obtained from the environmental radioactivity measurements and analysis around the nuclear power plants that have been carried out up to the present. In the korea standard, there is the technical analysis guide for general stable chemical element's, but there is not the technical analysis guide for the radionuclei. therefore the environmental sample collection, the pretreatment of the sample and radionuclide analysis in the sample, the result's of the environmental radioactivity measurements by each organization, etc. are different. It is not sufficient for the database to forecasting a change in radioactivity's circumstances. A comparative study of collection and pretreatment techniques for the soil sample, the results by comparison, the method of minimizing the relative error are proposed. At one side of sample collection, there are going to considered that the surroundings of sample collection like the lay of the land, the provision of the selection standard for the area and pathway of radionuclide adhesion, the coherence of sample collection, etc.. at another side of pretreatment of the sample and measurement in the case of soil sample, how to do homogeneously the soil particle size and the standard tools, i.e. kinds of meshes, must to be selected.
