Three nominated types of table salt samples are obtained from different sources: “cok” rooks table salt, “sal” red sea marine table salt, “Dr.salt” table salt with low sodium content prepared for hypertensive patients to procedure in this work labeled C, S and D respectively. Characterization of the table salt types using X-ray diffraction (XRD) analyses and the energy dispersive X-ray (EDX) analysis was carried out. EDX analyses show a difference in sodium and chloride content percentage atomic ratio between the three salt types. Also, potassium is apparent in the salt type D. The positions of each diffraction peak maximum intensity were obtained and compared with the corresponding peak in the database. Also, to discriminate the diffraction peaks of the impurities.Samples were irradiated with gamma source using Co60 at room temperature. Electron spin resonance (ESR) has been studied in the three different commercial table salt samples. The aim of the present study is to investigate the sensitivity of the naturally occurring table salts to gamma radiation, using the ESR technique The ESR results represent the signal intensity of the salt types C is higher than S than D. The results also indicate that, the ESR intensity of the table salt and the sensitivity to gamma radiation increases with increasing the percentage of sodium and also some other impurities in each content type.
