Robert
L. Fleischer, research
professor of geology, wrote an article “Fission Tracks in Solids – Production
Mechanisms and Natural Origins” in the June 15, 2004 issue of the Journal of Materials Science. It describes how energetic nuclear
particles cause radiation-damage tracks in solids by producing atomic
disordering. Fleischer also gave a talk, “Etched Tracks and Serendipitous
Dosimetry,” at the 14th International Conference on Solid State
Dosimetry held at New Haven. Co-authors were Sekyung Chang,
Jeremy Farrell, Rachel C. Herrmann, 
Jonathan MacDonald, and Marek Zalesky and Robert H. Doremus of Rensselaer. The talk described retrospective
personal dosimetry using etched-track methods.
