In the present study, the concentrations of ²²⁶Ra, ²³²Th, ²³⁸U, and ⁴⁰K in 10 different samples of foodstuff are investigated using a gamma spectrometer with a Sodium iodide detector NaI(TI). The results indicated that the concentration of ²²⁶Ra, ²³²Th, ²³⁸U, and ⁴⁰K in the samples ranged from (19.14 to 99.79) Bq/kg for radium, the activity concentration of Thorium ranged from (31.09 to 124.93) Bq/kg, the activity concentration of uranium ranged from (24.86 to 103.01) Bq/kg and the activity concentration of potassium ranged from (101.83 to 480.92) Bq/Kg. The results indicated that the annual gonadal dose equivalent (AGDE) of ²²⁶Ra, ²³²Th, and ⁴⁰K in the samples were higher than the permissible level (0.3mSv/y), except samples (S3, S5, S8).
