The study of soil pollution and measuring the concentrations of radionuclides in
the soil is of utmost importance, because many factors lead to an increase in these
concentrations, and thus the nuclides move from the soil to plants and livestock and then
to the human being, causing him serious health risks. Where taken 15 samples of soils
from Al Rahmah district, Where the reagent of Thallium-impregnated Sodium Iodide
NaI(TI) was used to measure the specific activity of the 226Ra, 232Th and 40K nuclei, the
specific activity values were varied from (0.526 -5.385) Bq.kg-1 with mean (2.193 Bq.kg1
) for 226Ra, (0.56 -5.29) Bq.kg-1 with average (2.95 Bq.kg-1
) for 232Th and (209.239-
990.387) Bq.kg-1 with mean (598.714 Bq.kg-1
) for 40K, respectively. Specific activity
values showed that there was only a significant increase in(
40K )concentrations, while that
the difference between the rate of Thorium and Radium concentrations was little
.External and internal hazard indices, outdoor and indoor absorbed doses and Radium
equivalent activity and total annual effective dose which were below the internationally
recommended limits. The excess life-time cancer risk ( ELCR ) was ( 0.717*10-3
) which
compare with the worldwide value(1.45*10-3
), this is the first study in this region and
can be considered as a baseline for future studies in this region.
