Effective atomic number - Wikipedia, the free encyclopedia
Effective atomic number has two different meanings: one that is the effective nuclear charge of an atom, and one that calculates the average atomic number for a compound or mixture of materials. Both...

Atomic number - Wikipedia, the free encyclopedia
In chemistry and physics, the atomic number (also known as the proton number ) is the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus....

Extending this idea of the effective atomic number of a material for specific radiation, Hine4 pointed out that there is a different effective atomic number for each absorption process in a heterogeneous material, but he could obtain expressions only for the photoelectric and pair production processes as Z 3.1 eff = p i...

Abstract. A theoretical method is presented to determine the gamma-radiation build-up factors in various biological materials. The gamma energy range is 0.015-15.0 MeV, The dependence of the exposure build-up factor on incident photon energy and the effective atomic number (Z eff ) has also been assessed.
