| 摘 要： | 通过对太平洋、印度洋、南极普里北湾表层海水中＾９０Ｓｒ、＾１３７Ｃｓ的分析，可以看出北半球放射必疹高于南半球。南极海域活度最你荒废 域人工放射性核素仍与大气沉降有关。全球人工放性活度吾下降趋势，但各海区下降的程度不同。南极普里兹湾夏季深层水的通升是影响该海区放射性水平的一个重要因素。局部区域的人工放射必不知 度与采样时间和地理位置有关。

| Abstract: | Based on the analysis of 90Sr and137Cs in surlaee seawatem from the Pacific, the Indian Oceans and Prydz Bay in the Antarctic, it bas been found that the radioactive level in the Northern Hemisphere is higher than that in the Southern Hemisphere with the lowest in the Antarctic sea area.the artificial radionuclides in the Antarctic bear a relationship with atmospheric steeing. The level of artificial radionucldes on earth shows a decrease tendency and with defferent degree in eadh sea area.The upwelling of deep seawater in summer in the Prydz Bay,Antarctic is an important factor affecting the radioactive level in this area.The activity of artificial radionuclides in some areas has a relationship to the location and time of sampling. |
