Politrack ® It is a multi-purpose solid-state nuclear track automatic scanning and analysis system, which can be used for track etching research, environmental radon concentration, radon personal dose and neutron dose measurement. The system includes track measurement microscope optical system, three-axis electric scanning system, high-resolution CCD camera and special measurement and analysis software. The main advantage of the system is that the user can change any track identification parameters (area, perimeter, area perimeter ratio, long and short axis, gray value, incidence angle, etc.) as required to identify the background signal and tracks with different energies.

CR-39 detector capable of measuring any size (maximum size: 200mmx200mm);

All parameters can be set by the user;

Track overlap, aging and decay correction can be performed;

Track analysis of complex morphology can be performed;

The stored images can be analyzed and calculated twice without scanning again;

Automatic detector ID identification;

For neutron track analysis, there are two measurement modes: fast neutron and thermal neutron;

Scientific research;
