1. 부산, 공수, 일광, 월내의 4개 지점의 해수의 방사능을 G.M. counter에 의해서 측정하고, 그때의 수질의 다른 요인도 아울러 규정하여 이와 함께 그 변화를 비교하였다. 2. Radioactivity는 Salinity에 비례하여 증감하였다. 그것은 염분속의 K와 밀접한 관계가 있다고 생각된다.
The distribution of the radioactivity of seawater along the coast and the adjacent sea of Korea has not been reported. Therefore it is neccessary to investigate this to give the basic data for reference in the field of the project applying atomic energy. A power plant of atomic energy projected by the government of R. O. K., and the Atomic Energy Agency has commenced to make general survey in geographical, meteorological and oceanographical aspects of proposed sites for it. It is a part of that survey in the field of the oceanographical investigation. The results of examination of sea water near those sites together with the fresh water of the rivers in those area are reported in this paper
