Radioactive radium and lead isotopes determinations in biota samples

210 Pb and radium’s isotopes were determined in biota samples by two different radiochemical techniques—Fe(OH) 3 co-precipitation and calcium phosphate precipitation. The applied procedures were adapted for very small amount (0.25 g) of sample material and were checked in actual biota samples. Measu...

Description
Summary:210 Pb and radium’s isotopes were determined in biota samples by two different radiochemical techniques—Fe(OH) 3 co-precipitation and calcium phosphate precipitation. The applied procedures were adapted for very small amount (0.25 g) of sample material and were checked in actual biota samples. Measurements were made by liquid scintillation counting, α- and γ-spectrometry. All the results show that Ca 3 (PO 4 ) 2 precipitation technique is better for determination of trace radionuclide concentrations in biota. The procedure of separation is stable with significant yield for the both 210 Pb and radium’s isotopes and can be successfully used for assessment of environmental stressors in field of bio-monitoring.
