Applications of neutron-induced fission-fragment detection techniques in studies of spatial distribution and uranium content measurements in solid materials using an optical microscope and a spark counter

Abstract

In Part I, the paper gives a general background of the registration and development of fission tracks in solid materials, and the conventional, optional methods of measuring induced-fission tracks. In Part II, the construction and use of a Spark Counter are described, together with applications to the U-content measurement and spatial-distribution in some actual geological samples.
