Abstract The purpose of the present work is to use Klein-Nishina formula to calculate the electronic cross-sections, atomic cross-section, transfer cross-sections, Compton mass attenuation coefficients and mass-energy transfer cross section of 83Bi209, 74W184, 48Cd112, 30Zn65, 28Ni59 and 26Fe56 when photon beams and γ-ray photons of various energies interact with these elements. The results reveal that all these cross-sections and coefficients are strongly dependent on the energy of photon E and the charge number of the material used. The cross-sections and coefficients decrease with increasing photon energy in the range of 0.284 MeV – 7 MeV, and increase with increasing charge number Z or charge number to mass number ratio Z/A. The conclusion describes that fundamental quantities and parameters like Z, E of photon beam and Z/A of these elements can be used and controlled to make them very useful for radiation shielding and protection and radiation dose measurements.

使用改进的 Klein-Nishina 公式表征 83Bi209、74W184、48Cd112、30Zn65、28Ni59 和 26Fe56,用于辐射屏蔽和剂量测定

摘要 本工作的目的是利用Klein-Nishina公式计算83Bi209、74W184、48Cd112、48Cd112的电子截面、原子截面、传递截面、康普顿质量衰减系数和质能传递截面。 30Zn65、28Ni59 和 26Fe56 当光子束和各种能量的 γ 射线光子与这些元素相互作用时。结果表明,所有这些横截面和系数都强烈依赖于光子 E 的能量和所用材料的电荷数。在 0.284 MeV – 7 MeV 范围内,横截面和系数随着光子能量的增加而减小,并随着电荷数 Z 或电荷数与质量数比 Z/A 的增加而增加。结论描述了基本量和参数,如 Z,
