Abstract
In current study, from Al.Rahmah district soil samples were collected .The Sodium
iodide detector NaI (Tl) was used to calculate the concentration of 226 Ra, 232 Th and
40 K% in ppm unit. The average concentration for the three radionuclides has been
found to be 0.1776, 0.7261, 1.9128% respectively. Radiological hazard of
representative level index (RLI), activity utilization index (AUI), concentration index
I C , Alpha index (I α ), annual effective dose (AEDE), excess life-time cancer risk
(ELCR) and Annual Gonadal Dose Equivalent (AGDE) have been estimated. From
results, the radiological hazards have been lower than permeation level recommended
by UNSCEAR. On the other side, the ELCR was being 1.2819*10 -3 , it was below
internationally recommended limits by UNSCEAR. Radiological hazard were
statistically measured to get the relation between all the parameter. The Pearson
correlation (PC) and statistically significant (p-value <0.05) were estimated. In this
study, the area is considered safe and does not pose a health risk.
Keywords: Soil; Radionuclide; Radiological Hazard; NAJAF; Iraq.
