The task of radiation safety management by the optimization of protective structures parameters has been
considered. The techniques for calculating the attenuation coefficient of radiation of multilayer floor slabs, the range
of constructional materials and the method of the optimization calculation of multilayer protective structures have
been analyzed. The analysis has shown that the achievement of the maximum possible efficiency of protection at
random distribution of materials is improbable. The optimization task has been solved of the distribution of
materials on protective structures and their constructional elements and the list of target functions and restrictions
has been made. The algorithm and the program have been developed, the method of optimization calculation of a
group of protective structures for the purpose of increasing personnel radiation safety has been improved, and the
calculation data testifying the efficiency of the offered approach have been obtained.
INTRODUCTION
The risks of accidents, disasters, terrorist attacks and
the use of nuclear weapons are still present in the world.
Industrial, social, political and military emergencies are
the causes of excessive radioactive exposure affecting
the population and the personnel of facilities.
The most cost-effective means of collective
protection in areas with low population density and non-
numerical personnel are simple protective structures and
shelters. The effectiveness of protection against ionizing
radiation, including gamma radiation, largely depends
on the tightness and absorption capacity of the slab
constructions and enclosing surfaces.
In the event of an increased risk of an emergency
situation, the building of protective structures is usually
carried out at an accelerated pace. It can be carried out
individually and in a group manner. The group method
in which a group of protective structures are built using
common resources (budgetfunds and constructional
materials) is of particular interest. In both cases the task
of the efficient use of available resources arises.
The existing methodology for calculating the
gamma-radiation attenuation coefficient of multilayer
enclosures and slabs takes into account a set of
conditions. They include: the number of layers, the
thickness of each layer and the half-value thickness.
However, this method does not allow achieving the
maximum protective effect with limited resources (of
budget funds and constructional materials).
The relevance of the work is dictated by the need to
develop the most effective radiation exposure protection
of people under the conditions of limited resources.
The objective of this work is to optimize the group
of protective structures, aimed at improving the anti-
radiation protection of people meaning to the optimum
choice of materials and their distribution over
constructive elements of the protective structure. At the
same time, the target function accepts the maximum
value, and the restrictions are respected.
OPTIMIZATION OF CALCULATING
THE PARAMETERS OF A GROUP
OF PROTECTIVE STRUCTURES
For the best distribution of material resources and
achievement the maximum protective effect, the task of
optimization for the chosen quality criterion (target
function) and fulfillment of restriction conditions is
solved.
The works [1, 2] are concerned with the study of
hybrid polymer composite materials for electromagnetic
screening. Despite the effective suppression of
electromagnetic interference and radio frequency range
radiation, these materials are not effective against
gamma-radiation protection. In the work [3], a
protective concrete structure is developed and the
required thickness of the slabs with improved shielding
properties at the permissible dose of irradiation of
personnel is calculated. This material is more effective
for protection against radiation. However, the reduction
of radiation exposure due to a combination of used
materials was not considered.
The paper [4] deals with the characteristics of
multilayer composite slabs to protect people and
electronics from radiation in space. The data on using
some materials as fillers are presented. The
improvement of protective properties due to the
properties of materials is achieved, but the optimization
task of maximum protection against radiation was not
solved. The paper [5] shows the optimized design of the
multilayer screen for protection against radiation.
However, the task of minimizing radiation exposure by
combining the materials used was not considered here
either. The paper [6] is devoted to the determination of
dependence of exposure dose on the dimensions and
materials of buildings. That research does not solve the
problem of the group optimization of anti-radiation
enclosures.
The problem of group optimization of enclosures
based on the Monte Carlo random search method was
solved in the papers [7, 8]. The method includes a free
choice of structures, calculation methods and prepared
materials, as well as their distribution over the
partitions. After that the restrictions are checked. A
persistent improvement is achieved due to the multiple
stochastic process of calculating the result up to an
acceptable value. The method assumes several variants
of setting the optimization task, in which the enclosures
are optimized in order to protect people from external
influences. The task of increasing the radiation safety of
people was not considered in these works.
Fig. 1 shows the simplest shelter model that
underlies the calculation.
Fig. 1. Simplified model of protective structure
(section): 1–3 – layers of absorbing materials
(3 – bearing layer);4–6 – layers of facing materials;
7 – protected space
To solve this problem, the following initial data set
is proposed:
– the desired gamma-reduction coefficient;
– the target function depending on the option
selected;
– the list of restrictions;
– the list of available materials for each
constructional element (see Fig. 1);
– the list and the amount of available materials;
– the number and the capacity of protective
structures;
– the unit cost and half-value thickness of gamma
radiation attenuation for each prepared material.
The following options for the target function are
available:
– the average gamma-attenuation coefficient;
– the total cost of the protective structures;
– the “safety/cost” ratio.
When selecting a target function, one should be
guided by the relevance of the optimization task under
the specific conditions. The average gamma-radiation
attenuation coefficient characterizes the degree of the
collective protection. This indicator is recommended for
accelerated building activity with the known results of
the forecast of the radiation situation.
The average gamma attenuation coefficient is
calculated from the formula:

situation), R/hr; in – individual protective structure

31 DD – thickness (cm) of the absorbing layer 1, 2,
and 3, respectively (see Fig. 1); 31 dd – thickness
(cm) of the half-reduction layer 1, 2, and 3, respectively.
The total cost of a group of protective structures is
an estimate that includes the cost of the materials,
fasteners and work. This target function is
recommended for pre-construction activity and an acute
shortage of financial resources:

where S – cost, c.u.; j

number and quantity of typical constructional elements
in a building; jV
and jC – respectively, the amount
(m

) and the cost of the material (c.u.) including
fastening elements and work.
The safety/cost ratio is a composite indicator. It can
be used when none of the previous indicators can be
given any priority:

The following restrictive criteria are proposed:
– minimum permissible value of gamma-radiation
attenuation coefficient of a single structure unit MINK ;
– maximum permissible total cost of protective
structures MAXS , c.u.;
– number of built structures *
NBSm .
The value of gamma-radiation attenuation
coefficient for an individual protective structure is
estimated by the inequality:
MINj KK . (5)
The cost of the protective structures is estimated by
means of the inequality:
MAXSS . (6)
The quantity of the built structures is estimated by
the expression:

If necessary, the restrictions can be imposed on
weight, mechanical strength and capacity of people.
IMPROVEMENT OF THE METHOD
AND THE ALGORITHM
OF OPTIMIZATION CALCULATION
OF A GROUP OF PROTECTIVE
STRUCTURES
This optimization task is based on discrete sets,
which include the lists of protective structures,
constructional elements and prepared materials. The
target functions and restrictions are generally non-
linear. Therefore the problem can be solved by the
methods of nonlinear discrete programming.
In this paper, the Monte Carlo random search
method has been used, similarly to [7, 8]. The
calculation algorithm is shown in Fig. 2. It uses the
stochastic process of random distribution of prepared
materials among the protective covers and structural
elements. The multiple calculation of the target function
and verification of restrictions allow choosing the best
result.
Fig. 2. Diagram of the algorithm for calculating a
group of protective structures
The advantage of the method and the algorithm
consists in blocks 2–4. In contrast to works [7, 8], the
prepared materials are distributed over different
protective structures and separate constructional
elements. The use of the target functions (1), (3), and
(4), as well as restrictions (5)–(7) makes it possible to
increase the radiation safety of people.
CONFIRMATION OF A SIGNIFICANT
EFFECT IN ACHIEVING THE OPTIMUM
SOLUTION
To confirm the effect, a computer program has been
developed and a verification calculation of four simplest
protective structures has been performed (see the model
in Fig. 1). According to the predetermined conditions,
the protective structures were located in the area with
the same level of radiation. The floor dimensions of
each structure were 5 2.5 m and the height was 2.5 m.
They housed 15 people. The minimum permissible
gamma radiation attenuation coefficient was 70. The
allowed materials for building the shelters are given in
Table 1. The characteristics of the materials are given in
Table 2.

stochastic calculation process (see respectively, block 2

As it can be seen in Fig. 5, the best optimization
result was obtained at the number of iterations 10
6
. The
further increase in the number of iterations does not
have a noticeable effect. Therefore, this result can be
considered optimal. The optimal plan of materials
distribution over the slabs is given in Table 3.
The average gamma radiation attenuation coefficient
for the structures was 119. The result of one-time
random distribution of materials, corresponding to the
minimum number of iterations, was 81. Thus, as a result
of the optimization this index has increased by 1.5
times. Thus, the effect of increasing radiation safety has
been confirmed.

The enhanced approach is characterized by the
algorithmic simplicity, and can be used for operational
building of a small number of simple protective
structures (units). The increase in the number of
structures and constructional elements requires an
increase in the amount of calculations. This will require
the use of more sophisticated optimization methods and
computer programs.
CONCLUSION
The following tasks need to be completed in order to
achieve the following objectives:
– the statement of the optimization task of
calculating the group of protective structures has been
carried out. The statement of the task includes the initial
data, variants of target function, restrictions and
recommendations on their use;
– the method and the algorithm of optimization
calculation by introducing changes aimed at improving
the radiation safety of people has been improved.
A significant effect when achieving an optimal
solution has been confirmed by a calculated way. As a
result of the optimization, the average reduction
coefficient of gamma radiation of the group of
protective structures has increased by 1.5 times.
Accordingly, the total dose absorbed by humans under
the conditions reviewed will also be reduced by 1.5
times.
