SUBMICROSCOPIC OBSERVATION OF FISSION-PRODUCT TRACKS IN MICA

The method of folding the replica of tracks has been shown to be a use ful tool to analyze nuclear tracks at submicroscopic level. To date, t his methodology was applied only to organic SSNTD. In the present stud y its applications are extended to an inorganic material. Muscovite mi ca was irradiated with fission products and replicas of track profiles were evaluated by TEM tip to 10 angstrom resolution. The tracks showe d a central, amorphous damaged region and an external bulk zone where the crystalline nature of the mica was presented.
