A semi-empirical approach for determination of low-energy gamma-emmiters in sediment samples with coaxial Ge-detectors
(Elsevier, 2004)
A simple method for the determination in sediment samples of low-energy gamma-emitters with coaxial Ge detectors and using a cylindrical sample geometry is outlined. This method allows an easy estimation of self-absorption ...
