Distribution of ²²⁴Ra in the Jiulong Estuarine waters and its application

Department of Oceanography, Xiamen University, Xiamen 361005

摘要

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.
