초록

경기도 수원시에 있는 한 대학의 두 건물(오래된 건물과 새 건물)의 실내외(지하, 옥상)에서 2013년 4월 첫 주부터~ 2014년 3월 말 주 까지 1년간 1주일에 2회씩 환경방사선량을 측정한 결과 다음과 같은 결론을 얻었다.
1. 두 건물의 환경방사선량은 0.169727μSv/hr이었고, 가장 작게 측정된 값은 0.076μSv/hr이었고, 가장 높게 측정된 값은 0.300μSv/hr이었다.
2. 오래된 건물의 환경방사선량이 0.176374μSv/hr, 새 건물이 0.163053μSv/hr로 오래된 건물에서 더 높게 측정되었다.
3. 1년 중 가장 낮게 환경방사선량이 측정된 달은 11월로 평균 0.152844μSv/hr이고, 가장 높게 측정 된 달은 5월로 평균 0.197222μSv/hr이다.
4. 측정 장소 비교에서 실내의 환경방사선량은 0.164649μSv/hr, 실외는 0.174779μSv/hr로 실외에서 높게 측정되었다.
5. 계절별로 가장 낮게 측정된 환경방사선량은 겨울로 0.157788μSv/hr이고, 가장 높게 측정된 계절은 봄 0.183846μSv/hr이며, 봄, 여름, 가을, 겨울 순으로 적게 측정되었다.

영어초록

The amount of environmental radiation was measured in the indoor(basement) and outdoor(rooftop) of the two buildings of the University (the old building and the new building) in Suwon City, Gyeonggi Province. Measuring the environmental radiation dose from the first week of April 2013 to last week of March 2014, Twice a week, one year. The measured results were as follows.




1. The average annual environmental radiation of the two buildings were 0.169727μSv/hr. The lowest value was 0.0760μSv/hr whereas the highest value was 0.3000μSv/hr.
2. The amount of environmental radiation dose was 0.176373999μSv/hr in the old building and the amount of environmental radiation dose was 0.163052885μSv/hr in the new building. The old building environmental radiation dose was higher then the new building.
3. The month of the lowest amount of environmental radiation dose in a year was November resulting in 0.152844μSv/hr whereas May was found the month of the highest amount of environmental radiation dose showing with 0.197222μSv/hr.
4. The amount of environmental radiation dose in the indoor(basement) was 0.164649μSv/hr and the amount of environmental radiation dose of the outdoor(rooftop) was 0.174779μSv/hr. And the outdoor(rooftop) was higher than the indoor(basement).
5. Depending on seasonal, the lowest amount of environmental radiation dose was in winter with 0.1632μSv/hr while spring was the season with the highest amount of environmental radiation dose with 0.183846μSv/hr. The measured amount was high in the order of spring, summer, autumn, and winter.
