R.E. Faw and J.K. Shultis "Absorbed-Dose Buildup Factors in Air for 10- to 100-MeV Photons," Nuclear Science & Engineering, 114, 76-80 (1993).

Buildup factors are reported for the absorbed dose in air resulting from point isotropic sources of monoenergetic photons with energies from 10 to 100 MeV. Factors were calculated from photon fluences computed by the EGS4 code for coupled photon and electron transport. Comparisons are made with results of moments-method calculations and with buildup factors computed directly from localized energy absorption.
