Radon Concentrations

In this study, concentrations of radon and uranium were measured for twenty six samples of soil. The radon concentrations in soil samples measured by registrant alpha-emitting radon (222Rn) by using CR-39 track detector. The uranium concentrations in soil samples measured by using registrar fission fragments tracks in CR-39 track detector that caused by the bombardment of U with thermal neutrons from 241 Am-Be neutron source that has flux of 5 ×103n cm-2 s-1.The concentrations values were calculated by a comparison with standard samples The results show that the radon concentrations are between (91.931-30.645Bq/m3).The results show that also the uranium concentrations are in soil samples under 0.051-0.0079ppm.

In this study a concentration of uranium was measured for twenty two samples of soil distributed in many regions (algolan, almoalmeen, alaskary and nasal streets) from Falluja Cityin AL-Anbar Governorate in addition to other region (alandlos street) as a back ground on the Falluja City that there is no military operations happened on it. The uranium concentrations in soil samples measured by using fission tracks registration in (PM-355) track detector that caused by the bombardment of (U) with thermal neutrons from (241Am-Be) neutron source that has flux of (5×103n cm-2 s-1). The concentrations values were calculated by a comparison with standard samples. The results shows that the uranium concentrations algolan street varies from(1.976- 2.736ppm), almoalmeen street varies from (1.895-2.614ppm), and alaskary street varies from (1.657-2.476ppm), and nasal street (1.657-2.476ppm) the average uranium concentration in other region (alandolos) (0.736-1.588ppm). As a conclusion from the study uranium concentration in the four region above that have military operations is relatively higher than back ground

Uranium is a common radioactive element in Earth’s crust (soil, rock), so it is important there quantity to be under control. The concentration of uranium in soil varies widely, Depending on the geological location, its concentration in the surface soil vary from 0.1 mg.Kg-1 (ppm) to 20 mg.Kg-1 (ppm) with a world average of 2.8 ppm and the allowed limit that equals 11.7 ppm. The uranium concentration, radon activity, radon concentration, in twenty soil samples collected from AL-Hamdaniya region (East of Mosul city) were measured using the sealed-can technique based on the CR-39 SSNTDs. The estimated values for the uranium activity which equal to radon activity at secular equilibrium were found vary between (581.11-1453.5) mBq with mean value 905.89 mBq, the uranium concentration are between (0.313-0.784) ppm with mean value of 0.488 ppm. All values of the samples under the test are below of allowed limit and world average value.

The aim of this research is to determine the uranium concentration in soil and water samples taken from different locations from the middle and south of Iraq using fission fragments track registration. Twelve samples of soil and water were taken from middle and South of Iraq. The nuclear reaction used as a source of nuclear fission fragments is U-235 (n.f) obtained by bombardment U-235with thermal neutrons from (Am-Be) neutron source with flux (5X103 n.cm-2.s-1). The concentration values were calculated by a comparison with standard samples recommended by IAEA.The results of the measurements show that the uranium concentration in soil samples were in Thekar (16.38 ppm), AL-Basra (16.1ppm) and (0.78 ppm) in Baghdad, from the results which show that this governorate were contaminated with depleted uranium after the Wars against Iraq . The uranium concentration in the water samples of Tigers river were in AL-Qurna (8.85 ?g/l) and in AL-Suwera (4.72 ?g/l).

      In this study, the CR-39 detector technique was used, to estimate the uranium concentration from the soil in midland refineries Company (Doura refine (, Baghdad, Iraq. Uranium concentrations in soil samples have been measured using solid state nuclear track detector type CR-39.  Nine soil samples were collected from different areas within the Doura refinery and other soil samples were collected form Abu Tayara Street and ALshortaa District outside the refinery for comparison. The results showed variable values for uranium concentrations. The average value of uranium concentration was found to be 0.37 ppm in doura refinery. For areas outside the refinery, the concentration of uranium was 0.008 ppm. These results were less than the global limit.

Radon Concentrations

Measurements of radon concentration, effective radium content, potential alpha energyconcentration (PAEC) and annual effective dose (AED) were estimated for soil samples in fifteen locationsof the Baghdad governorate (Karakh) in the central part of Iraq. In this survey we used the can technique,containing nuclear track detector (CR-39). The obtained values of radon concentration measurements weregenerally low, ranging from 38.12±13.46 to 94.51±16.5 Bq/m3, with an average 66.07 Bq/m3, while theeffective radium content varied from 5.80±0.21 Bq/kg to 14.39±0.33 Bq/kg with an average 10.09 Bq/kg. The average of the PAEC and AED were assessed to be 7.14 mWL 1.66 mSv/y, respectively. The resultsof the present study shows that the radium content are lower than the allowed limit reported by Organizationfor Economic Cooperation and Development (OECD) that is equal to 370 Bq/kg. In general, it is seen thatthe AED limit was within the recommended reference level (3 mSv/y to 10 mSv/y) of the World HealthOrganization. Also, it is found that there is a strong correlation (R2= 1) between radon concentrations andeffective radium content. The results obtained from this study indicate that the locations of Karakh hasbackground radioactivity(radon concentrations) levels within the natural limits.
