Determination of uranium in aqueous attenuating samples using gamma-ray spectrometry

In the present work, a method for determination of uranium concentration in aqueous solution in standard geometry from attenuating samples has been developed based on modification of the empirical approach of Venkataraman and Croft [2003. Determination of plutonium mass using gamma-ray spectrometry. Nucl. Instrum. Methods Phys. Res. A 505, 527–530]. The method makes use of the multiple gamma (γ)-rays emitted by 235U and depends on the empirical relation between apparent mass of the sample and γ-ray energy. It was possible to determine uranium concentration in the range of 12–400 mg/ml rapidly by this method without applying transmission corrections.
