Dose buildup factors for normally incident 662-keV gamma rays penetrating multilayered aluminum-lead slabs were measured for various combinations using thermoluminescence dosimeters. The results were compared with calculated values obtained from a gamma-ray transport code and with values inferred from a ...

Besides, energy absorption buildup factor (EABF) and exposure buildup factor (EBF) of inorganic metal halide cubic perovskites have been determined using the Geometric Progression (G-P) fitting method at energies 0.015–15MeV up to penetration depths of 40 mean free path (mfp). The examined ...
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 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
The age of the furnace is another factor that influences the need for repair. Most furnaces have a lifespan of 15 to 20 years, depending on the quality of the system and the level of maintenance it receives. Older furnaces are more prone to breakdowns and may operate less efficiently than...
