Solid State Nuclear Track Detection (SSNTD): A Useful Scientific Tool for Basic and Applied Research

'SSNTD' stands for Solid State Nuclear Track Detection, one of the most fascinating nuclear particle detection techniques, developed to date. It has been found to be equally useful in basic and applied research work, particularly for scientists, engineers, and technologists in the developing countries. This paper, very briefly, summarizes the useful contribution this technique has made in the past and is making at present. The state of the art of applications of Solid State Nuclear Track Detectors in fields like nuclear physics, geochronology, cosmology, biology, bird altimetry, seismology, elemental analysis, material science, lithography, etc. has been given. Some of the future applications have also been pointed out.
