通过结晶固体的重电离粒子可能产生损伤痕迹，这可以通过电子显微镜直接观察到，也可以通过优先化学溶解损伤物质间接观察到。在使用这两种方法的情况下，已经表明化学攻击方法更敏感。据报道，这种揭示辐照效应的方法也能显示重粒子在许多非晶体材料中的路径，在这个例子中是玻璃。结果表明，Cf252的裂变碎片在玻璃上留下了损伤痕迹，这些痕迹可能被蚀刻成圆锥形的凹坑。在一些玻璃杯中，锥角很小，以便运动粒子的方向可以被跟随。裂变轨迹也可以在某些玻璃中通过沿损坏区域的金属如银的优先沉淀而显示出来。这种方法的优点是轨迹不必与自由表面相交即可显示。
Heavily ionizing particles passing through crystalline solids may produce trails of damage which can be seen either directly by electron microscopy or indirectly, by means of preferential chemical dissolution of the damaged material. Where both methods have been used, it has been shown that the method of chemical attack is the more sensitive. Here it is reported that this method of revealing irradiation effects is able also to display the paths of heavy particles in a great many noncrystalline materials, in this instance glass. It is shown that fission fragments from Cf252 leave damage trails in glass which may be etched to give conical pits. In some glasses the cone angles are small, so that the direction taken by the moving particles may be followed. Fission tracks can also be revealed in certain glasses by preferential precipitation of a metal such as silver along the damaged regions. This method has the advantage that a track does not have to intersect a free surface to be revealed.
