In the present work, the enhancement of radioactivity due to rainfall in the Aegean Sea using floating measuring systems was observed and quantified. The data were acquired with a NaI underwater detection system, which was installed on a floating measuring system at a depth of 3m. The results of natural and artificial radioactivity are discussed taking into account the rainfall intensity and wind direction. The activity concentration of (214)Bi increased up to (991+/-102)Bq/m(3) after strong rainfall in the North Aegean Sea in winter (humid period) with east wind direction. On other hand, the maximum activity concentration reached the level of (110+/-10)Bq/m(3) in summer (dry period) during south winds.
在本研究中，利用浮动测量系统观测并量化了爱琴海降雨导致的放射性增强情况。数据是通过安装在深度为3米的浮动测量系统上的碘化钠水下探测系统获取的。结合降雨强度和风向，讨论了天然放射性和人工放射性的结果。冬季（湿润期）北风强劲时，爱琴海北部强降雨后，（214）Bi的活度浓度增加至（991±102）Bq/m³。另一方面，夏季（干燥期）南风期间，最大活度浓度达到（110±10）Bq/m³。
