Diffusion silicon pool alpha detectors

A diffusion silicon pool alpha detector for measuring solution alpha activities is described. The sensitive detector surface makes contact with the liquid but the signal does not depend on its electric conductivity. The production process of the detector with the p-n transition formed as a result of phosphorous diffusion is described. The given detectors have more stable characteristics in comparison with the surface-barrier detectors. They can be used for determination of the α-active element concentrations in an electric conductive and a non-conductive media
