Abstract
A γ-ray source of ≈300 keV was used in order to excite the fluorescent K-radiation of the heavy elements which is only weakly absorbed in the walls of metal tubes. Thus, uranium can be determined quantitatively in solutions within tubes in the concentration range form 5 mg/l to 100 g/l. The influences of the energy and the activity of the radiation source, the geometrical arrangement, the thickness of the wall and the wall material have been investigated.
