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.

Abstract

Radon activity concentration levels were measured in the sediments of Basrah Governorate marshes, Iraq. There included Al-Qurna marsh and Al-Mediena marsh. The selected areas were chosen according to civilian population. CR-39 and LR-115 type 2 detectors in a cylindrical plastic container technique used in this investigation. Maximum activity of radon levels (18329 Bq m-3) observed in Al-Hyader sediments and minimum levels (1769 Bq m-3) were observed in Umelha both samples from Al-Mediena marshes. While in all sediments of Al-Qurna marsh, the activity of radon were found between (10740-1985) Bq m-3 which are in natural limits according to (ICRP). The anomalous values of activity of sediments in some stations were discussed .

تم قياس مستوى فعالية تركيز الرادون في رواسب اهوار محافظة البصرة (العراق) وتتضمن اهوار القرنه والمدينه واختيرت مناطق الدراسة حسب التجمعات السكانية. استخدمت تقنية الاسطوانة المغلقة للكاشفين CR-39 و LR-115 type2 في هذه الدراسة. لوحظ ان القيمة العظمى الفعالة للرادون ((1829 Bq m-3 في منطقة الحيادر والقيمة الصغرى ) (1769 Bq m-3 في منطقة الاميلحة وكلتا المنطقتين تقعان في هور المدينة . بينما وجدت فعالية تركيز غاز الرادون في رواسب هور القرنة تقع بين 3(10740-1985) Bq m- والتي هي ضمن الحدود المسموح بها حسب (ICRP) . تم تحديد و مناقشة المناطق الشاذة في متن هذا البحث.
