Abstract
Right now, specific radioactivity of soil chose from Diwaniya Governorate was
estimated. Ten samples of this soil were gathered. These samples were from some
general education schools, where the samples were taken from diversified sites. to
define the specific activity from the radioactivity 232Th, 238U and 40K, Iodide sodium
system activated with Thallium 3"×3" had been used for this aim , finally for
Thorium 232Th ranged between (BLD-14.652) Bq.kg-1, average (5.334) Bq.kg-1. for
Uranium 238U, it is ranged between (BLD-26.187) Bq.kg-1, average (8.364) Bq.kg-1,
where the result showed that radio activity of potassium 40K ranged between
(346.823-536.704) Bq.kg-1 with a rate of (450.482) Bq.kg-1, The radium equivalent
values ranged between (33.951-68.194) Bq.kg-1, average (50.68) Bq.kg-1, the
absorbed dose rate in air ranged between (18.386- 33.995) nGy.h-1, average
(25.962) nGy.h-1, External hazard index ranged through (0.091-0.184), average
(0.136), Internal hazard index ranged through (0.091-0.226), average (0.159).
activity concentration index ranged between (0.293-0.538), average (0.409), the
observed results were below the International recommended limits.
