In this work, the activity concentrations of naturally occurring radioactive material including  238 U,  232 Th, and  40 K were measured of some amber rice samples cultivated in southern Baghdad and Al Najaf governorate and used in Baghdad governorate, Iraq in 2018, using gamma-ray spectrometer with NaI (Tl) detector. The results show that the activity concentrations for  238 U ranged from (2.68 to 10.81) Bq/kg with average 5.94 Bq/kg,  232 Th ranged from (B.D.L to 3.37) Bq/kg with average 2.65 Bq/kg, and for  40 K ranged from (4.48 to 35.7) Bq/kg with average 16.84 Bq/kg. The annual effective dose from rice consumption by adults for  238 U,  232 Th, and  40 K ranged from (0.41 to 1.6) x10-5 Sv/y with average 0.9 x10 -5  Sv/y, (B.D.L to 0.42) x10-5 Sv/y with average 0.2 x10 -5  Sv/y, and (0.17 to 1.2) x10 -5  Sv/y with average 0.45 x10-5 Sv/y respectively. All values of the average specific activities are less than the global average values of ICRP, and the annual effective dose from rice consumption by adults was lower than the permissible limit of (1 m Sv/y) recommended by the International Commission on Radiological Protection.
