Abstract
This research evaluates the level of radioactivity and the impact of radiological elements in Kavvayi's coastal areas, located within Kannur district. Radionuclide concentrations, including 40K,226Ra, and232Th, were quantified in sand specimens using a highly efficient NaI (Tl) detector. Several radiological elements, such as absorbed dosage, yearly effective dosage, radium equivalent activity, lifetime excess cancer risk, and yearly gonadal dose equivalent, were computed and juxtaposed with figures reported in global regions. These radiological elements were found to be moderately above the average values proposed by the UNSCEAR 2000 report for India and the world. Our investigation demonstrates that the gamma radiation in the researched region does not present significant carcinogenic risks or likelihoods of cancer development for local residents. Nonetheless, comprehensive research is required to conclusively determine the elevated levels of natural radioactivity in the area under study. The outcomes of these rigorous examinations are presented and discussed in depth.
