Abstract

The nuclear can be used to determine some characteristic parameters of algal and sediment. They are following: 1/ Using neutron activation analysis technique to determine the concentration of metals such as Mg, K, Mn, Co, Fe and Zn in algal and sediment samples. 2/ Using Pb-210 method for sediment dating and sedimentation rate in Cam-ranh gulf. The concentration of some metals such as: Mg, K, Mn, Co, Fe and Zn in algal is too high that causes Red-Tid and has increarsed in recently years in sediment samples. The sedimentation rate in Cam-ranh gulf has been carried out.
