The application of this method to problems involving the passoge of neutrons and-gamma.
quanta through a substance Is possible due to the absence of any interrelation between the
particles In real beams. The difficulties that arise In connectioa with the use of the Monte
Carlo method are concerned primarily with the determinatioti of small probabUlties. In
problems connected with the passage of radiation through a substance, the smallness of
the probability p may be occasioned by the absorptioa of the particles, their leakage from
the medium, energy losses as the result of slowing, etc. It is pointed out that the Keumaa
series for the solution of the Idnetic equation reduces the rafflaUon transfer problem to
the computation of mqltiple intervals, while the Alonto Carlo method itself consists
essentially In the calculation of the terms of a Neumma series which are the muldple
intervals. Thb use of non-random points, in the opinion of the authors, implies a repudiat!
of the probabilities of the Monte Carlo scheme, ellminating.the possibility of a practical
evaluation of the accuracy of the results. In those cases inwhich Interest attaches to a
particular functional of the kinetic equallon solution., the methods which are described
in this article for Increasing the statistical effectiveness -of the method normally provide V
aacuracy quite satisfacory for pracUcW purposes with a number of histories ranging fror

The semi-analytical Monte Carlo method Is briefly discussed. This method Is based an
the use of analytical solutions (provided such are possible) for certain ramificatl6ne -of
the basic straying process. The essential Idea of the "control variablo method" Is ex-
plained. This technique Is sometimes also called the "correlation sampling method".
The point Is made that the chief difficulty in the use of this method consists in flading"
random value- k of high correlation with r the mathematical expectancies
of which are Q&. We %iethod of local stream calqUItioa Is discuoFed and eumples
