Description | ||||||
The aim of this research is to determine the buildup factors which are involved in studying gamma attenuation in some kinds of shielding material such as aluminum, iron and steel. So, samples with dimension [76mmx76mmx0.9mm] and [76mmx76mmx1mm] are made. Then the photon attenuation after passing through the investigated samples is carried out by using NaI detector. The experimental arrangements include 2"x2" NaI (Tl) scintillation detector (Model No. 2M2/2), the photomultiplier tube base (digiBASE) with USBconnection and MAESTRO-32 gamma detection software installed in a computer. 137Cs source is used for the incident photon beam. By analyzing the spectra the photon intensities before and after the samples are obtained. From these, the attenuation coefficients and the buildup factorsfor the given samplescan be calculated by using the relative methods. | ||||||
