| dc.description.abstract | Devirli aktiflerce tekniğinde, numunenin ışınlanma ve ortaya çıkan radyasyonun sayılması işlemi birbiri ardına tekrarlanır. Amaç, gözönüne alınan, özellikle kısa yarı-ömürlü izotop için sinyalin doğal saymaya oranını arttırmaktır. Bu çalışmada, tekniğin matematiği, nümunenin ışınlama kaynağından sayaca yer değiştirme süresini de içerecek şekilde incelenip geliştirildi ve elde edilen teorik veriler eğrilerle gösterildi. Aydınlatıcı uygulama olarak, gama spektroskopisi ile kurşunun ve gecikmeli nötronlarla uranyumun en az gözlenebilme miktarları bu teknikte bulundu ve sonuçlar konvensiyonel teknikle elde edilenlerle karşılaştırıldı. | tr_TR |
| dc.description.abstract | In this paper cylic activation is the technique whereby a sample is rapidly transferred between irradiation source and radiation detector, repetitively, in order to enhance the signal to background ratio for the isotope of interest. Thus it makes possible the determination of certain toxic and essential trace elements in environmental/ biological samples, which produce short-lived isotopes on neutron irradiation. A reactor irradiation facility with a finite transit time is used and the system is found to be suitable for studying isotopes with half-lives from a second to a few minutes. A brief mathematical analysis of cyclic activation, which takes into account sample transfer times, is presented and computed critical parameters are provided in graphical form to help selection of experimental conditions. The application of the technique is demonstrated in the detection of lead by gamma - ray spectrometry and of uranium by delayed neutrons; comparison is also made of the detection limits achieved by conventional and cylic activation analyses. | tr_TR |
