Natural radioactivity and heavy metal distribution in reservoirs in Ghana
The present paper has determined the radioactivity concentrations, which are due to natural occurrence of radionuclides along with heavy metal concentration in water, sediment, and fish from 2 reservoirs in Ghana. Heavy metal concentrations in all samples were generally within the WHO safe limits with the average activity concentrations of 238U, 232Th, and 40K in water being respectively 0.42±0...

متن کاملMeasurement of Natural Radioactivity in Certain Types of Nut Samples in Iraq
Introduction: The present study was conducted to measure the specific activities of 226Ra,232Th and 40K, in some samples of nuts collected from the local markets in Iraq. In addition, this study sought to calculate the annual effective dose of gamma ray to children and adults. Material and Methods: The quantification of radionuclides was accomplished by gamma spectrometry NaI (Tl) detector. Res...
متن کاملGamma Radiation Measurement due to Natural Radioactivity in Hot Water Spring of Behbahan
Introduction: Many people use hot water springs to treat some diseases, such as rheumatism, arthritis, and skin diseases, but they are unaware of the presence of natural radioactive substances that may be found in hot water springs. An effective way to understand the radiation risk of these elements are measuring the dose rate of radiation. In this study, for the first time, ga...
