The biennial National Symposium on Radiation and Photochemistry (NSRP) provides an important platform for discussion on new research areas in Radiation and Photochemical Sciences. Since inception, NSRP has been playing a unique role in bringing together not only the pioneers but also young researchers in both the areas, yielding fruitful discussions and setting the course for future directions. This is the only national program, in which the subtle nuances of Radiation and Photochemistry are discussed on the same platform. The main topics are designed to include a wide range of subjects involving both fundamental aspects as well as applications of Radiation & Photochemistry. The symposium will constitute invited talks and presentations of contributory papers as posters.
