The estimated average background radiation concentrations in water samples in this region are low, related to the low level detection limits of the techniques, and the chemical parameters values are compared with the limits established by CONAMA (Comissão Nacional do Meio Ambiente / Brasil – a government agency responsible for Brazil’s environmental protection). There are good water quality parameters, and low interference in the environment in Centro Experimental Aramar and region.373-382openAccessalpha detectionalpha spectroscopybeta detectionbeta spectroscopyenvironmental impactsenvironmental protectiongamma detectiongamma spectroscopyliquid scintillatorsradiometric surveysscintillation countingwaterwater chemistrywater qualityArtigo de periódico36710.1080/00207230903138604
