جرى التركيز في هذه الدراسة على وضع إجراء لضبط جودة التحاليل و القياسات في مخبر مطيافية
غاما باستخدام كواشف أنصاف النواقل من الجرمانيوم عالية النقاء، و تحديد الخطوات الرئيسية لتقدير
الارتياب في نتائج القياسات و طرائق الاختبار و المعايرة و تعرف كفاءة الطريقة المستخدمة في الظروف
الحقيقية للتشغيل: المحلل، الجهاز، البيئة، المخبر و إلى تقدير المواصفات الإحصائية للطريقة و تقييمها،
بحيث تكون هذه المواصفات أساسًا لوضع معايير قبول النتائج أو رفضها، و لتقييم جودة التحاليل الناتجة عن
استخدام هذه الطريقة.
Quality Control procedure Of Gamma Spectrometry measurements using
semi conductor HPGe Detectors and determination the uncertainty budget of
the measurements and calibrations have been prepared.
Depending on this procedure we can evaluate the quality of the results to be
accepted or not, and where the correction actions should be used.
