DETERMINATION OF RADIOACTIVE DILUTION FACTOR OF SEA WATER AND STUDY OF METHODS |
|
Abstract: |
The dilution factor of sea water in a certain sea region off Qingdao was determined by using radioactive 60Co and Rhidamine-B as tracer agent, (NH4)2 Hg(CNS)4 as precipitant and by low-background counter to measure the β-activity of 60Co. This approach was shown to be of high sensitivity, easy operation and reliability, in addition to the relative smaller amount of isotope thrown into the sea water. |
