Purpose Characterization of soft tissue, water and air in terms of effective atomic number Z eff with respect to the interactions of hadrons, leptons and isotopes of hydrogen. Method Mass collision stopping powers MCSPs were calculated first using Bethe formula. Then, these values were used to estimate Z eff using linear-logarithmic interpolation. A scale equation was also used to .

Effective atomic number,EAN 1 EAN 8.sp, .

Effective atomic number is a term that is similar to atomic number but is used for compounds e.g. water and mixtures of different materials such as tissue and bone rather than for atoms. The effective atomic number is calculated by taking the fractional proportion of each atom in the compound and multiplying that by the atomic number of the .

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 are abbreviated Z eff.. For an atom. The effective atomic number Z eff, sometimes referred to as the effective nuclear charge of an atom is the number of protons an electron in the element .

The calculated value of the effective atomic number z tau of 7.23 for lithium tetraborate Li 2 B 4 O 7 agrees closely with the value of 7.22 for soft tissue of composition C 5 H 40 O 18 N. For excised muscle specimens the experimental value 7.42 obtained by Spiers for z tau is very nearly equal to the corresponding calculated value 7.46 for the composition ICRU of striated muscle.

Abstract. Radiological properties of gel dosimeters and phantom materials are often compared against each other and against water or tissue by consideration parameters including their effective atomic number, Z eff.Effective atomic numbers have been calculated for a range of ferrous-sulphate and polymeric gel dosimeters using mass attenuation coefficient data over the energy range 10 keV to 10 .
