Abstract: With the help of reactor neutron activation analysis investigations of trace elements such as copper manganese selenium nickel cadmium and mercury have been performed with the purpose of differentiation between healthy persons and patients suffering from bilharzia diseases We applied the K method as a new standardization technique in which the deviation of the 1 E¹ epithermal neutron flux distributions from the 1 E law the true coincidence effects of cascade 'Yrays and the efficiency of the Ge (Li) detector were taken into consideration Shortlived nuclides were determined by a short activation with the help of a pneumatic irradiation facility with automatic correction of dead time and decay rate The medium and long lived nuclides were determined after 48 hours irradiation and ten days cooling The patients' head hair samples showed significant differences in Cu Zn and Cd but had no clear significant effect in Mn Ni Se and Hg The result obtained indicates that early diagnosis by means of trace element determination could be possible Unfortunately there are no similar published results for comparison
لتطبيق الفيزياء في الطب تم استخدام التحليل التنشيطي بالنيترونات لدراسة العلاقة بين تركيز بعض العناصر ومرض البلهاريسيا وذلك باستخدام طريقة K كأسلوب عياري جديد، وأخذ في الاعتبار معالجة مصادر الخطأ التي تؤثر على النتائج التحليلية ولوحظ أن هناك اختلافا واضحا في تركيز عناصر النحاس والزنك والكادميوم بين عينات شعر المرضى والأصحاء، بينما لم يلاحظ اختلاف يذكر لعناصر المنجنيز والنيكل والسيلينيوم والزئبق ولقد أشارت النتائج إلى إمكانية تشخيص مبدئي باستخدام هذه الطريقة، ولسوء الحظ، لا توجد نتائج مشابهة بحيث يمكن مقارنتها مع نتائج هذا العمل
