中文摘要:

Through the investigation on radioactive activities of water, sediment and some marine organismsin the Zhujiang Estuary, adjacent sea area and the distributary mouths of the Zhujiang River, activities of total α. radioactivity, total β radioactivity, artificial radioactive ⁹⁰Srand ¹⁵⁷Cs, and factors inflencing the distribution and the content of U in seawater are studied.
The mainly radioactive pollution substances and their sources in the sea area are studied by γ spectra obtained from sediment in the sea area. The results show that the main radioactivity substances are natural radioactivity U,Th series and ⁴⁰K. which were produced by the modern industry and transported into the sea through the main current of the Zhujiang River.
