WebFinal answer. Step 1/1. To design a gamma-ray radiation shield made out of Pb with a linear attenuation coefficient μ=0.771 [cm] that would attenuate a narrow beam of 1 MeV gamma-rays with a build-up factor of B = 2 to one thousandth (10^3) of its initial strength, we need to use the gamma-rays exponential attenuation law: μ I ( x) = I 0 e ... WebThe Gamma ray attenuation equation can be wriiten as =Number of transmitted photons or final intensity =Initial number of photons or initial intensity =Linear attenuation constant t=thickness of absorber tHe good geometry means the ga … View the full answer Transcribed image text: 1.

WebJan 27, 2024 · Recently, a novel and high-precision method for calculating the γ -ray build-up factor for multilayer shields has been proposed in this paper. The method is based on the deep neural network (DNN) [ 19, 20 ], which is a kind of machine learning. Webcoefficients and the values of the build-up factor for each absorber were found. Theoretical Treatment . Gamma rays are simply emitted whenever an excited nucleus returns to its ground state and such excited nuclide is said to be radioactive. A good example of this gamma rays emitting radioactive nuclide is an isotope of element of Cobalt, 27. Co اعداد رومی ساعت دیواری
