Spark counting of α-radiograms recorded on LR-115 strippable cellulose nitrate film

Abstract

In this paper a study on the spark counting of etch-holes of α-particle tracks recorded on 13 μm strippable cellulose nitrate track detectors (Kodak-Pathé LR-115 films) is described. Results for the counting characteristics as a function of etching and irradiation parameters are given. Applications of the spark counting technique to α-radiograms obtained by the (p, α) nuclear reaction and soil-radon exhalation measurements are presented.
