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

  • Received Date: 1997-08-11
  • Rev Recd Date: 1997-11-21
  • 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.
