The concept of buildup factor was first introduced by White (White, 1950; Harima, 1993) during the analysis of the penetration and scattering of gamma rays in water. The buildup factor represents the ratio of the total radiation intensity dose to the unattenuated intensity and it can be ...
Calculation of point isotropic buildup factors of gamma rays for water and lead Exposure buildup factors for water and lead have been calculated by the Monte-Carlo method for an isotropic point source in an infinite homogeneous medium,... MH Alamatsaz,AA Shirani - 《Iranian Journal of Physics...
The efficient and convenient substance to use as a shield against gamma photons depends on two important properties which are buildup factor and the coefficient of linear attenuation,so adoption of study of these two properties had been done in the polyester composite shield (PCS) supported by dif...
Our results show that for Cs source the dose correction factors are of the order of 3% to 8%. A theoretical model for calculation of dose correction factor in brachytherapy in the presence of inhomogeneities has been developed. The model calculates DCF using buildup factors for the water-...
The magnetic flux rope is among the most fundamental magnetic configurations in plasma. Although its presence after solar eruptions has been verified by spacecraft measurements near Earth, its formation on the Sun remains elusive, yet is critical to unde
Buildup factors for energy deposition in water and aluminum and for exposure in concrete are presented for monoenergetic, point isotropic gamma-ray sources. The buildup fac. tors were evaluated using the method of moments and are tabulated for energies from 0.03 to 10 MeV and distances out to...
