Abstract. Eleven samples of salt were collected from local markets in Iraq for the
purpose of identifying which types were more radioactive and the radiation efficacy
of the external hazard index, outdoor absorbent dose, internal hazard index and
indoor absorbed dose and Radium equivalent activity (Raeq) also finding an effective
dose due to ingestion where the maximum value of a specific uranium activity was
recorded in sample S4, which was (32.138Bq/kg). The lowest value was recorded in
sample S8, which was (4.432 Bq/kg). It should be noted that sample S8 is Turkish
origin specific activity of 232Th, the highest value was (12.456Bq/kg) recorded in
sample S9, while the lowest value was (1.426 Bq/kg) and recorded in sample S7.
Also calculate Effective dose Dose(Sv/y) by using equation (7) for 40K was 10.088
Sv/y , 226Ra was 1.152 Sv/y and 232Th was 1.660 Sv/y.
