The development of the Video Intensified Microscope coupled with digital image processing techniques offers a new way to quantitatively measure tritium concentration in metallographic mounts. Beta particles from the decay of tritium strike a scintillation film placed on the sample causing photons to be generated. The photon signal emitted from the sample is digitized and stored in an array of pixels within a digitizing board. The time required for the acquisition of these images is on the order of minutes instead of the hours or days normally required for traditional photographic autoradiography techniques. By utilizing the techniques of digital image processing and analysis, tritium concentration can be statistically analyzed. Depth profiling of tritium into a material and two dimensional concentration gradients can be plotted and analyzed. These images are also saved to optical disks for later recall and comparison and archiving. 5 figs.
