THE DETERMINATION OF GROSS BETA RADIOACTIVITY IN SEA WATER AND SEDIMENT IN THE XIAMEN HARBOUR AND THE JIULONGJIANG RIVER ESTUARY

Abstract:

Gross Beta radioactivity in sea water and sediment in the Xiamen Harbour and the Jiulongjiang River Estuary was determined in 1981. The value determined varies from 1.4 to 3.3 pCi/1 in sea water, with a mean activity of 1.9 pCi/1, and 3.2 to 5.3 pCi/kg·dry weight in sediment, with a mean activity of 4.0 pCi/kg·dry weight. The horizontal distributions of the gross Beta radioactivity in the sea water and the sediment showed a tendency of increase from south to north, which seemed to be correlative with the high gross Beta radioactivity in the Jiulongjiang River water and the tidal motion.
