In this study, 30 samples of lung cancer patients were collected from Middle Euphrates Oncology Center in Najaf, Iraq. A plastic track CR-39 Reagent technique, strippable was used to measure radium and uranium concentrations. Normality was a washing solution) NaOH ) was6.25 to clarify chemical drilling to read under the electron microscope to calculate alpha particles paths. Effective radium content values were ranged from 0.1592 Bq / kg to 3.2278 Bq / kg with an average value of 1.246Bq/kg where uranium concentrations values were ranged from 5.5671ppm to 112.8615ppm with an average value of 43.5883ppm for healthy human compared with patients were effective radium content values were found from 0.261Bq/ kg to 3.286 Bq/ kg with an average value of 1.345 Bq/kg where uranium concentrations values were found to be from 9.1099 ppm to 114.8859 ppm with an average value of 47.052ppm. A positive relationship was observed between Radium concentration and uranium concentrations in blood samples. Measurements of Radium and uranium concentrations in lung cancer patients, this research important in terms of health protection, simple and reliable analysis methods which available.
