Abstract:

The Modified Elemental Volume Dose Program MEVDP generates ordered path-length areal densities for primary electron, electron-bremsstrahlung, and secondary particle radiation transport calculations. The code also generates standard-material areal-density distribution functions for proton and heavy ionizing nuclear radiation. The primary and secondary areal-density functions can be used for particle transport calculations to compute emergent fluxes and energy deposition. The code has been successfully run with the complex Apollo command and service modules and the lunar modules, which are represented by 1000 elemental volume shield configurations. The MEVDP has evolved as a versatile, accurate, and fast executing program.
