This study reviewed radiological research works conducted in the state of Kelantan, Peninsular Malaysia. A total number of eleven research articles available to the authors were reviewed and reported accordingly in this paper. From the studies it was observed that not much has been done in revealing the radiological state of the region despite been blessed with abundant granitic rock deposit. Some of the papers reviewed reported the presence of high activity concentration of naturally occurring radionuclides i.e. 238U, 232Th, 226Ra, 228Ra, 222Rn, and 40K in some study areas like work of (Siti Afiqah et al, 2012; Mohammed Kasim et al, 2011 etc.) while few studies were reported to be below the global and Malaysian average as can be seen in the text.
