| 摘 要： | 研究了九龙江河口区表层水体中224Ra的分布,发现同世界其他河口一样,224Ra在九龙江河口区呈非保守行为;同时发现224Ra-Ss关系受季节变化的影响显着;与世界其他河口相比,九龙江河口表层水体中224Ra含量偏高;用九龙江河口区海端溶解态224Ra估算九龙江河口水流向外海的流速在夏季为2.5cm/s,冬季为0.91cm/s.

| Abstract: | The distribution of 224Ra in the jiulong estuarine waters has been investigated.The results show that 224Ra is non-conservative in this estuary,just as the other estuaries of the world.Varition of 224Ra activities with salinities is examined and 224Ra-S relationship is affected obviously by the seasons.The maxina of dissolved 224Ra in the jiulong estuarine waters is(37.7±1.6)Bq/m3(s=15.57) during spring and(37.7±0.2)Bq/m3(s=18.68) during winter.Based on dissloved 224Ra data,the current speeds of the jiulong estuarine waters seaward are estimated as 2.5 cm/s in summer and 0.91cm/s in winter. |
