Applicability of the LSC technique for determining 210Pb in liquid samples for purposes of dose assessment via in vitro bioassay

Brazilian Journal of Radiation Sciences, 2022
A new approach for the determination of 210Pb by liquid scintillation counting was developed by the LBIOVT. In order to assess the applicability of the technique for internal monitoring of occupationally exposed workers and members of the public, some ...

Natural radionuclide and 137Cs activity concentration in soils of the Brazilian State of Sergipe and their correlation with environmental characteristics

Brazilian Journal of Radiation Sciences
Radionuclides occur naturally in the environment, exposing living organisms to ionizing radiation. In addition, human activities have introduced artificial radionuclides such as 137Cs, among others, into the environment.
