Abstract
A method for the identification of alpha-emitters sampled from contami nated surfaces in nuclear facilities with adhesive tape is described. It was found that the thickness of such a sample is sufficiently thin for the observation of alpha-lines. When a solid state track detector is used, the density of the alpha-particle tracks can be measured with in the range 10(5)-10(7) alpha-particles per cm2. A procedure for obta ining alpha-particle autoradiographs of the sticking tape samples with a nitrocellulose solid state detector is developed.
