FLAIR: A Scaling and Folding Code for the Generation of Photon Transport Results in Air.

摘要

The FLAIR code was developed to easily and inexpensively generate x-ray and gamma-ray transport results in infinite air by utilizing an existing data base of x- and gamma-ray transport computed by Monte Carlo. FLAIR provides energy, angle, and time-dependent photon transport results from energy and time-dependent photon sources in infinite air. Results are possible out to ranges of fifteen mean-free-paths and are scaled with air density. FLAIR is oriented toward benchmarking radiation environments from weapon systems and calculating differential fluxes for input to radiation response codes. (Author)
