给出了一套完整而一致的公式，用于计算所有类型材料和大于1keV的所有光子的有效原子序数和电子密度。它们是利用组成原子的光子相互作用截面从第一原理推导出来的。对具有医学和生物学意义的分子、辐射屏蔽玻璃、合金、矿物和液体的计算和实验证明了这一理论。(C)2008爱思唯尔B.V.保留所有权利。
A comprehensive and consistent set of formulas is given for calculating the effective atomic number and electron density for all types of materials and for all photon energies greater than 1 keV. The are derived from first principles using photon interaction cross sections of the constituent atoms. The theory is illustrated by calculations and experiments for molecules of medical and biological interest, glasses for radiation shielding, alloys, minerals and liquids.
