Disponível em: http://repositorio.ipen.br/handle/123456789/28225.http://repositorio.ipen.br/handle/123456789/28225Due to the importance of human life, water quality must be controlled and a very important parameter are the limits of the natural radioactivity of the water consumed.In relation to therapeutic practices based on water intake the radionuclides 210Pb , 226Ra and 228Ra when present, are of great importance because they contribute to the internal irradiation of individuals.The study areas of the present work were the Parque das águas of Cambuquira and Marimbeiro, located in Minas Gerais. Hence, the objective of this work was to determine the 226Ra, 228Ra and 210Pb concentrations in the springs of these parks and evaluate the committed effective doses due to its consumption.The radionuclides were determined by a radiochemical procedure in four collections at different seasons of the year. The Concentrations ranged from 4 ± 1 mBq / L to 509 ± 32 mBq / L for 226Ra, from 3.7 ± 0.1 mBq / L to 631 ± 27 mBq / L for 228Ra and 5 ± 1 mBq / L to 60 ± 5 mBq / L for 210Pb. The dose for adults from 1.21x10-01 mSv/y for 226Ra, 3.18x10-01 mSv/y for 228Ra and for 210Pb 3.02x10-02 mSv/y.openAccessconcentration ratiodose commitmentsdose equivalentsecological concentrationlead 210natural radioactivityradon 226radon 228water springsTexto completo de evento
