Radon concentration measurements in sludge of oil fields in North Oil Company (N.O.C.) of Iraq


In this study the assessment radon concentration in sludge of Oil Fields in North Oil Company (N.O.C.) of Iraq have been studied using CR-39 solid–state nuclear track detector technique. A total of 34 samples selected from 12 oil stations in the company have been placed in the dosimeters. The average radon concentration was found to be 162.29 Bq/m3 which is fortunately lower than the standard international limit. The potential alpha energy concentration and annual effective dose have been calculated. A proportional relationship between the annual effective dose and radon concentration within the studied region has been certified.
