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 the present work, Radon Excess Lung Cancer (ELC) is estimated for fourteen soil samples from Babylon cement plant in Iraq. CR-39 nuclear track detector is utilized to measure the uranium content and radon 222Rn concentrations in soil samples. Uranium concentrations in soil samples varied from 0.008 to 0.05 ppm with mean value 0.025±0.013. Radon concentrations is founded between 31 and 92 Bq/m3 with mean value 56.72 and standard division, SD, 17.29. Radon Excess Lung Cancer per Million Persons per Year is determined with mean value 863 and standard division, SD, 261.65 (463.81-12082.8). Also, Annual effective dose, E (msv y-1), has a range from 0.77 to 2.32 with mean 1.44 and SD 0.44.

Abstract. The objective of this present work is determining some heavy elements concentrations like (Cd, Co, Mg, Mn, Fe, Cu, Ni, Pb & Zn) in thermal electric power stations in the middle and south of Iraq. 18 Fly Ash samples were collected from thermal electric power stations in the middle and south of Iraq ,the concentration values of (Cd, Zn , and Fe ,Mg, Cu) in some samples were over the international limits in the Fly Ash samples .In general the increasing of the heavy metals in some fly ash samples due to the releasing of these metals is the combustion of the fuel and fuel type which provides thermal electric power station different from units to other , and geology of the region collected samples from it and the geochemical characteristics of the crude oil.
