The simple procedure of the detector active zone thickness determination is proposed, in which the fluxes of fluorescent radiation analytical lines from single-component samples excited by monochromatic radiation of a secondary radiator are used as the known fluxes. The superposition of experimental and calculated curves of the analytical line intensity versus the wavelength allows determination of the active zone thickness d = 170 μm with an accuracy of ± 10 μm.
