- A fast method for the determination of 210Pb by LSC in liquid samples Camilla da Silva Sampaio Wanderson de Oliveira Sousa Bernardo Maranhão Dantas Biología 210Pb in vitro bioassay liquid scintillation 210Pb is a naturally occurring radionuclide, widely distributed on the earth´s surface and can be incorporated by humans through food chain or directly by ingestion or inhalation in situations of occupational or accidental exposures. Because of its metabolic and dosimetric characteristics, 210Pb becomes an important isotope from the radiation protection point of view. This work presents the development of a methodology for the determination of 210Pb by liquid scintillation. It is the modification of a sequential analysis for naturally occurring radionuclides in environmental samples without the need of waiting for secular equilibrium to be achieved with 210Bi that allows a faster determination of 210Pb. The methodology has shown to be precise, stable and provides consistent results when evaluated according to the criteria established in the Brazilian Intercomparison Program promoted by the IRD. This technique can be applied to any sample after proper digestion and in liquid form. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280899006 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.7
