Radioactivity measurements of different types of salt using SSNTD

摘要

Salt analysis is very important due to its high consumption by the population and for its medicinal use. In this research, I used twelve samples of different types of salt (local, imported and rock) collected from different locations. They have been investigated using Solid State Nuclear Track Detectors (CR-39) and Titrimetric method. It is found that the annual effective dose was calculating from corresponding radon concentration range between 10.47-13.69m Sv year-1 with average 11.8775m Sv year-1 which are higher than the recommended value, and it is found that the percentage of purity was 55 % in the rock salt. Given these fmding, it appears that salt contamination of groundwater could increase the potential for human exposure to these radioactive.
