Intercomparison of automatic fission track counting systems

Abstract

The methods of counting fission tracks by two image analyzing computers and a spark counting system are compared with a standard microscopy technique. In this comparison, for automatic fission track counting, the two commercially available image analyzer instruments, the Quantimet 720 and the Leitz-Texture Analyzing System (TAS) and a specially designed spark counter, the UTASC system, have been used. The results showed that the relative counting efficiencies of the Quantimet 720, the Leitz-TAS and the UTASC system are 0.974±0.010, 0.988±0.013 and 0.955±0.010, respectively
