Abstract:

This study was carried out to find the optimal method for the detection of radiation defects in alkali halide crystals. The experiments were carried out with NaCl, KCl, and LiF crystals irradiated with indium gamma rays of 10 to the 9th power rad. The surfaces of the specimens were studied on an electron microscope by the replica method described by D. Kay Techniques for electron microscopy, Oxford, 1961. The experimental results show that radiation defects in alkali halide crystals can be studied by means of an electron microscope and that it is expedient to use the carbon replica method for studying the structure of defective surfaces of ionic crystals. The method seems to be sensitive enough also to detect the effect of irradiation with a smaller dose of the order of one million rad of gamma rays. Author
