Abstract
Abstract Damage track detectors have unique capabilities for measuring low concentrations of natural and man-made alpha emitters in biological and environmental samples. With electronic devices such as surface-barrier detectors, zinc-sulphide screen counters and large area grid ionization chambers, the detection sensitivity is limited by the duration of exposure or the stability of electronic counting systems. Damage track detectors can be used for sufficiently long exposure periods so that the intrinsic background of the detector material can be ignored. In particular, the applications of damage track detectors, described in this paper, refer to the assessment of low concentrations of Uranium, Plutonium and radon, using the registration of alpha-particle and fission- fragment tracks. The sensitivity and the simplicity of track counting can be greatly enhanced by using the spark counter.
