The study was conducted for the investigation of amount of radioactivity in the
different Touirij region in Iraqi town in the province of Karbala, is located just 108 km to the
southwest of the Iraqi capital Baghdad. The technique of gamma ray spectrometry was applied
using NaI(Tl) gamma ray detector and a PC based Maestro Activity concentration levels due to
40K, 238U and 232Th were measured in. Activity concentrations ranges of the concerned
radionuclides for the soils were as follows: 40K was (271.2-170) with the average (245.1), 238U,
(30.96-5.86) Bq/Kg with the average (19.45)Bq/Kg, and 232Th, (67.09-2.9) with average(24.47)
Bq/Kg respectively. The results have been compared with those of different countries of the
world and Iraq. To assess the radiological hazard of the natural radioactivity, the absorbed dose
rate, the radium equivalent activity (Raeq), the effective dose rate (Eeff), the annual effective
dose equivalent (AEDE), Excess Lifetime Cancer Risk (ELCR), the radioactivity level index
(Iγ), and the external (Hex) and internal (Hin) hazard indices were calculated. It can be
concluded that no risk may threat the residents around and center of Holy shrines . Hence the
probability of occurrence of any of the health effects of radiation is low. Hence, measurements
have been taken as representing baseline values of these radionuclides in the soil in studying
