Assessment of gamma emitter levels in cereal samples, revealing implications for human consumption and health safety.
The limits of radionuclides contained in foods should be minimal for safe human consumption. This study examined the radiological hazards of 238U, 232Th, and 40K in cereal samples, for three age groups—infants, children, and adults—using a NaI(Tl) detector. The results ranged from 5.67 ± 0.61 to 11.82 ± 1.09 Bq/kg, 2.27 ± 0.29 to 9.76 ± 0.61 Bq/kg, and 152.37 ± 3.34 to 323.63 ± 7.56 Bq/kg, respectively, and showed that the levels were within the limits set by UNSCEAR: 238U = 33 Bq/kg, 232Th = 45 Bq/kg, and 40K = 420 Bq/kg.
