The main achievements in atomic and nuclear physics research using the track detection

Some main achievements obtained by the authors in the atomic and nuclear experimental physics research using the fission and/or alpha track micromapping technique are described. An experimental checking out of natural radioactive decay by emission of heavy ions, the U biodistribution, retention and elimination in the internal contamination of animals, investigations on the fissionable element dispersion systems, including the stabilization/changes of the dispersion states of these systems as well as the sorption of the dispersed phase on the different 'insoluble beds', fissionable element atom distributions and their content measurements in any liquid and solid samples, references material remedying and preparation procedures and several applications of the fission track method in reactor physics, geochronology and industry are briefly presented and exemplified by photos.
