Abstract

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.
