Abstract EN
This study reported activity concentration of 238 U, 232 Th.
40 K in 50 soil samples AL- Nada district - Najaf Govemorate - Iraq Measurement using gamma ray spectrometer Nal (TI) (3 x 3).
The activity concentrations of natural radionuclides are found to range from (31.319 ± 0.741) Bq.Kg-1 to (1.1583 ± 0.0821) Bq.Kg-lwith average (11.851 ± 0.281) Bq.Kg- 1 of uranium 238U.
From (1.117 ± 0.048) Bq.Kg-1 to (23.948 ± 0.649) Bq.Kg-1 with an average of (6.283 ± 0.148 ) Bq.Kg-1 for thorium -32Th..from( 13.592 = 0.282) Bq.Kg-1 to (705.834±6.179) Bq.Kg-1 and average (265.494 ± 1.445) Bq.Kg-1 potassium^K .
equivalent radium from (12.489 ± 0.328) Bq.Kg-1 to (84.199 ± 1.911) Bq.Kg-1 and average (40.078±0.564) Bq.Kg-1 .
internal hazard index from (0.039) Bq.Kg-lto( 0.256) Bq.Kg-1 and average( 0.139) Bq.Kg-1.external hazard index ranged from( 0.033) Bq.Kg-1 to (0.227) Bq.Kg-1 and average( 0.108) Bq.Kg-1 values either of absorbed dose in air from (5.728±0.150) nGy.h to (42.667 ± 0.901) nGy.h and average(19.914 ± 0.264) nGy.h .
internal annual effective dose from (0.028±0.0005) mSv/'y to (0.209 ± 0.0044) mSv/y and average (0.097 ±0.0013) mSv/y, external annual effective dose from (0.0070 ± 0.0001) mSv/y to (0.0523 ± 0.001) mSv/y and average (0.0244±0.0003) mSv/y The results were found to be comparable or lower than similar global reporting data.
According to this, research soil The area can be considered to have a normal level of natural background radiation
