Abstract
A large amount of radionuclides in the sandform is deposited from Tanthien (10°37.875'N; 107°43.696'E) to Kega cape (10°41.943'N; 107°59.518'E) along the coach of Hamtan (Binhthuan province). The U-238 and Th-232 radionuclide series causes a very high exposed dose in the environment. A total radioactive concentration in a typical deposit is about of 2600 Bq/Kg. This value is over a radioactive exemption to a normal material and the deposit has to be called a radioactive material. The correlation between a total radioactive concentration and exposed dose is established and its value is closely to unit. The radiometric methods is applied in this study are surface exposed dose surveying by pocket dosimeter and radionuclide quantitative analysis by a Ge (HP) gamma spectrometry.
