The danger arising from exposure to natural radionuclides as a result of working in Majnoon oil field in Southern Iraq

The natural radioactivity levels of Majnoon oil field, 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-97 & MJ-95 plants at different depths. Activity concentrat...

Description
Summary:The natural radioactivity levels of Majnoon oil field, 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-97 & MJ-95 plants at different depths. Activity concentrations were obtained for the 238U series (226Ra, 214Pb, and 214Bi), the 232Th series (228Ac, 212Pb, and 208Tl) series and 40K. Results show the high radiative values obtained for some samples are due to the technically enhanced NORM (TENORM) in this area when compared with average global values. Radium equivalent activity (Raeq), absorbed dose rate (D), annual effective dose rate (AEDE), external hazard (Hex), internal hazard (Hin) and gamma radiation level index (Ig) were also obtained and compared with the international recommended values. It was concluded from these results that the high values obtained for the specific activity values of some radioisotopes at certain altitudes, as well as some radiation risk parameters, because this field is one of the very old fields.
