Abstract

Gamma ray exposure buildup factor for some ceramics such as boron nitride (BN), magnesium diboride (MgB2), silicon carbide (SiC), titanium carbide (TiC) and ferrite (Fe3O4) has been computed using five parametric geometric progression (G.P.) fitting method in the energy range of 0.015 to 15.0 MeV, up to the penetration of 40 mean free path (mfp). The variation of exposure buildup factors for all the selected ceramics with incident photon energy, penetration depth, and chemical composition has been studied.

光子能量、穿透深度和化学成分对某些陶瓷γ射线暴露累积因子的影响

利用五参数几何级数(G.P.)拟合方法，计算了氮化硼(BN)、二硼化镁(MgB2)、碳化硅(SiC)、碳化钛(TiC)和铁氧体(Fe3O4)等陶瓷在0.015 ~ 15.0 MeV的能量范围内，至40平均自由程(mfp)的伽马射线暴露累积因子。研究了所选陶瓷的曝光累积因子随入射光子能量、穿透深度和化学成分的变化规律。
