Tchebycheff-Fitted Berger Coefficients for Eisenhauer-Simmons Gamma-Ray Buildup Factors in Ordinary Concrete

Coefficients are given for the two-parameter Berger empirical formula fitted to air kerma and concrete kerma buildup factor data provided by Eisenhauer and Simmons (E-S). The fit is such as to minimize the maximum deviation of the resulting formula predictions from the basic E-S data. Comparison with similar work by others is provided.
