Abstract

تحوي غالبية المياه الطبيعية قليلاً من اليورانيوم المنحل . وفي الحالة العامة ، فإنه من الصعب إجراء التحليل الكيميائي الروتيني المباشر لمثل الكميات الصغيرة لليورانيوم . إن تقانة مطياف غاما أسهل وأقلّ كلفة ، ودقيقة على حدٍّ سواء ، بالمقارنة مع العديد من الطرق الأخرى للتحليل .

لقد تمَّ تكريس هذا العمل لدراسة ميزات مطياف غاماGamma spectrometer  : الفعالية Efficiency ، وضجيج الخلفية Background . ونجري هنا حساب الحساسية Sensitivity ، لقياس اليورانيوم في الماء ، بوساطة مطياف غاما . ومن ثم ، تم قياس كمية اليورانيوم الموجود في مياه منطقة لوديف Lodève القريبة من مدينة مونبيلية الفرنسية بعد زيادة تركيزها خمس مرات . وأخيرا ، فإننا نستخلص طريقة أساسية للقياس الكمي لآثار اليورانيوم في الماء الطبيعي .

Natural water contains usually a little amount of dissolved uranium. In general, it is difficult to analyze directly such small quantities of uranium in water by routine chemical methods. Gamma spectrometer technique is easier, less expensive and equally accurate compared to many other methods of analysis.

This work is concerned with the gamma spectrometer characteristics: efficiency and background. We make here sensitivity calculus, for measuring uranium in water with use gamma spectrometer. Then, quantity of uranium had been measured in the water in "Lodève" area near Montpellier French city by increasing the concentration five times. Quantitatively, there is a substantial method to measure uranium in the natural water.
