Abstract
The differential determination of203Hg and14C or35S in double labelled biological samples is presented. The biological samples were mineralized with 70% HClO4 and 30% H2O2 in minivals MILLI-6. The γ-activity of203Hg was measured on a well scintillation counter. The total activity, due to203Hg and14C or35S, was measured by the liquid scintillation technique after addition of Aquasol into the same vials. The method of external standard channel ratio was used for standardization. Very good recoveries were obtained: 100±0.7% for203Hg and 94.6–101.0% for14C and35S. This method could be used for other β, γ and β-active nuclides with similar β-spectra.
