摘要

This study investigated the radioactivity levels of 226Ra, 232Th, and 40K in locally processed and industrially refined salt samples from Ebonyi State, Nigeria. Results showed higher activity concentrations of radionuclides in locally processed salt compared to the industrially refined salt. Consequently, locally processed salt exhibited higher radiation doses (absorbed dose rate, annual effective dose rate, and annual gonadal dose equivalent) than refined salt. These findings highlight the potential radiological impact of consuming locally processed salt and emphasize the need for radiation protection measures for workers in the local salt industry.
