Natural radioactivity measurements in soil and dates samples from groves of the Shatt Al-Arab in Basrah governorate

Abstract EN

Natural radioactivity of (226Ra, 238U, 232Th, 40K), in Soil and Dates samples calculated from shatt Al-arab in Basra govermente were measured using gamma ray spectroscopy with NaI (Tl).

The results showed that the specific activity of (226Ra, 238U, 232Th, 40K (Bq/kg)) in Soil ranges from (1.

02, 0.

27, 0.

45, 219.

19) Bq/kg to (11.

21, 2.

73, 2.

77, 389.

51) Bq/kg and Dates ranged from (0.

58, 0.

21, 0.

36, 140.

20) Bq/kg to (6.

57, 1.

74, 2.

58, 273.

66) Bq/kg respectively.

The radium equivalent in Soil samples ranged from (11.

84) to (40.

4) Bq/kg and in Date samples ranged from (13.

41) to (25.

37) Bq/kg.

The annual effective dose equivalent AEDEin in Soils samples ranged from (0.

01) - (0.

09) µSv/y and for Date samples ranged from (0.

03) to (0.

07) µSv/y.

The results of the internal and external hazard index in Soil and Dates samples were all lower than the value of the global limit.
