METHOD AND DEVICE FOR THE SPECIFIC DETECTION OF (ALPHA) RAYS AND / OR (BETA) - AND (GAMMA) RAYS IN PROPORTIONAL COUNTER TUBES WITH THE PRESENCE OF EACH OTHER RADIATION TYPE AND APPLICATION

摘要

1. Method of differentiating between alpha rays on the one hand and beta and/or gamma rays on the other hand by means of at least one proportional counter tube, characterised in that the electrical signals produced by individual rays and occurring between anode and cathode of the proportional counter tube are differentiated on the basis of the then occurring current intensities of the counter tube current.
