Assessment of lung cancer risk due to exposure to radon from oil well in (Majnoon) Basra.

The natural radioactivity levels of Majnoon oil field (MJ-95), which is considered one of the oldest oil fields in Basra, were studied using scintillation detector gamma ray spectrometer with NaI (Tl) detector. Soil samples were collected from MJ-95 plants at different depths. Radon (Rn) concentrations within and outside the oil field were calculated using a set of formulae. The highest value in the sample in depth 2750m was 93.36Bq/m3 and the lowest value in the sample in depth 2850m was 0.58Bq/m3. The average risk of cancer caused by radon (deaths per million people) was 14.93. [ABSTRACT FROM AUTHOR]
