  • Title: Determination activity of radionuclides in marine sediment by gamma spectrometer with anti cosmic shielding.
    Author: Thanh TT, Ferreux L, Lépy MC, Tao CV.
    Journal: J Environ Radioact; 2010 Sep; 101(9):780-3. PubMed ID: 20537447.
    Abstract:
    In this work, the activities of radionuclides in a marine sediment sample have been determined. The gamma spectrometer comprises an N type coaxial HPGe detector with active shielding to reduce cosmic background. The mass activities of radionuclides have been derived and found to be around a few Bq kg(-1) to several hundreds Bq kg(-1) with relative uncertainties in this paper quoted corresponding to the combined standard uncertainties (k=1).
