PRACTICAL ASPECTS OF MULTI-DIMENSIONAL MONTE CARLO SHIELDING CALCULATIONS.

Abstract Multidimensional Monte Carlo programs exist which are capable of solving most radiation shielding problems. There are however practical problems which must be faced in applying these programs to specific situations. These problems concern geometrical description (input and computer algorithms), source description, importance sampling, scoring techniques, and cross section treatment. New techniques under development promise to reduce the present difficulties and make Monte Carlo a practical engineering tool for radiation transport calculation.
