AT.effective.Z.from.composition

atomic numbers of constituents (array of size n).

relative fractions of weight of constituents (array
 of size n).

weight.fraction

if not zero, weight fractions will
 additionally include electron densities per volume (array of size n).

electron.densities.cm3

exponent for additivity rule reflecting the photon energy
 regime (usually 3.5 at ~ 100 kV).

exponent

Computes the effective atomic number for a given material
 composition

R interface to the open-source, ANSI C library 'libamtrack' (http://libamtrack.dkfz.org). 'libamtrack' provides computational routines for the prediction of detector response and radiobiological efficiency in heavy charged particle beams. It is designed for research in proton and ion dosimetry and radiotherapy. 'libamtrack' also includes many auxiliary physics routines for proton and ion beams. Original package and C-to-R conversion routines developed by Felix A. Klein.
