Abstract

The parameters of environmental in some selected samples from Kufa in Najaf city was determined and discussed. Five soil samples were collected from:1- Housing grouped for kufa cement factory 2- Kufa river bottom3- Kufa bridge closeness (Kufa Environment office)4- Kenda-5- Gazwyniha We implemented a laboratory apparatus based on a NaI (Tl) γ-ray spectrometer, where connect the scintillation detector with multichannel analyzer.Results showed the presence of natural radionuclide Ra226 in soil samples. In order to evaluate the radiological hazard of the natural radioactivity, mean resulted Dose has been calculated. Chemical analysis for concentration of NO2-1, NO3-1 and PO4-3 the range of values (0.701-2.246),(2.55-13.236),(0.00-0.003)ppm respectively, also carried out along with the measurement of electrical conductivity and pH of the soils samples; the values range (272-9360) µScm-1 and (7.51-8.11), respectively.

Abstract

Level of radon concentration has been performed in south of Iraq's oil fields, at 72 well. Apassive integrating radon discriminative monitor was used in this study. Both LR-115 type II and CR-39 plastic track detectors have been used for the measurement of radon concentration in the Crude oilsamples. The investigation show great variability of radon concentration in each well. The highestvalue of radon concentration was observed in oil well number (119) in Al-Hammar field 993.4 Bq.m-3 ,while the lowest value observed in oil well number (76) in Al-Rafidhya field 195.9 Bq.m-3 .Thisvariation in concentration of radon in the well have been discussed in this study.
