tion which gives the attenuc-.ion of the stream of y-quanta with energy Ej from t!Ie
point of y-quantum production r to the points r, on the surface. A formula is derived
for the asymptotic value of 0 determined by the physical properties of the shielding
material alone. A comparison of theoretical ana experimeatal asymptotic values of 8
shows a systematic divergence by a factor of appioximately 2.5, the theoretical data
being overestimated. The reason for the divergence is assumed to be inaccurate deter-
mination of neutron intensities at the boundary. in 3pite of the discrepancy betveen
experimental and theoretical data, the nearly constant divergence obtained for various
elements with large, small and moderate capture cross sections (tungsten, lead, iron
and nickel) indicates that the proposed method may be used for calculatin.3 the asymp-
totic values of 0 with an accuracy of 30% if a correction factor of 2.6 is used. The

ABSTRACT: The authors note that in the design of nuclear reactors the use of con-':
jugate equations has proven to be extremely fruitful. in the present work, prob- i
lems of the conjugate equation theory are discussed in the light*of the study and '
calculation of radiation shielding. The basic problems encountered In the calcula-
tion of shielding are the computations of the following values: a) the neLLtron,
flow behind the shielding and the dose created by these neutrons; b) the flow and
dose of gamma quanta behind the shielding; c) the integral flows of neutrons in-
ci.dent to individual structural elements of the reactor and the shielding for the,
purpose of estimating the degree of radiation igairment of the metals; di thermal:. .

of neutrons. The different role (and, hence, danger) of the neutron in the re-
actor and in the shielding Is noted. Of the possible applications of conjugC610
functions to the theory of perturbations, the authors single out two for special
consideration. In the first place, a knowledge of the conjugate function makes
it possible to select the most rational positioning of the materials in the shield-
ing. In the second place. it makes Vt possible to derive the variations of the
values of interest to the specialist (dosages, thermal emissions, etc.), connected,
wi'th certain changes In the structure and planes of interaction, and also with
effects not previously considered, without the repetition of unwieldy computations,
but merely through the application of the perturbation theory ratio. From this
point of view, the authors consider and derive the formulas-of this theory and car-!
tain functions In the theory of shielding. The use of the.method of consecutive
:.approximations for the determination of-the optimal disposition of shielding J
materials Is considered, as Wall as the efficiency function of the shielding

shie;ding made of iron (and of Iron with 1% by weight of oron), 20 cm thick, in

ABSTRACT: The authors consider the problem of selecting the ratio of components in
reactor shielding to give minimum weight or overall dimensions for a given reduction
in radiation intensity or to achieve a minimum radiation dose for given shielding
weight or dimensions. The problem is formulated as a variational problem on the op-
timum of scme quantity when given conditions are imposed on other quantities. The
various approaches to solution of the problem given in the literature are briefly
reviewed. The physical characteristics of the shielding (neutron and gamma doses,
heat release, weight, etc.) are considered within the framework of perturbation
theory and the concept of functions of effectiveness of shielding materials is intro-

duced, i. e. functions which give information on the changes in various quantities
under given conditions which result from sane small change in the densities of the
materials. The classical methods of Yariational calculus are used for determining
optimum conditions for functionals representing the various physical characteristics
of the shielding. The method of successive approximations is used for solving the
problem of optimizing the distribution of shielding components in the general case.
An example is given illustrating applic,:,tion of the proposed method. Orig. art. has:
