1. INTRODUCTION
Radiation processing dosimetry is vitally important
for all radiation-technological processes based on elec-
tron beam (EB) irradiators. Control method of EB char-
acteristics in radiation processing by the wedge and
stack in conjunction with dosimetric films is well-
known and widely used in practice [1-3].
The idea of usage of a procedure of the dosimetric
wedge and stack in radiation processing is related with
determination of the depth-dose distribution of electrons
in an irradiated target for a flat one-dimensional case
and obtaining an information about characteristics of
EB on the basis of the solution of an inverse problem.
International standards determine the measurings
procedure for the depth-dose distributions with usage of
the dosimetric wedge and stack, experimental data treat-
ment and an interpretation of observed results [4,5].
Practical use of a procedure of the dosimetric wedge
and stack is related with utilization of a standard con-
struction of the devices that ensures only determination
and control of the most probable energy, Ep, and the av-
erage energy, Ea, of an EB. These information in some
cases testifies only about a level of stability of a radia-
tion processing.
Dosimetric devices of the reference sizes, made of
reference homogeneous materials, such as aluminum,
polyethylene, polystyrene, graphite, traditionally are
used in radiation processing. Empirical formulas defin-
ing values of electron energy for a monoenergetic beam
on value of the practical range Rp and half value depth
R50 of electrons in an irradiated material are known for
the reference materials.
The Rp and R50 values for electrons in the reference
materials are obtained on the basis of analytical approxi-
mation of the depth-dose distribution in a spatial field of
the strong decreasing of a dose in a dosimetric film lo-
cated between plates of the reference materials. In this
case the choice of a spatial field for analytical approxi-
mation is not formalized. It is obvious, that results of
such treatment of experimental data depend on spectrum
and angular distribution of electrons in an EB.
Derivable at such mathematical treatment of ob-
served data, the integral characteristics for passage of
electrons in substance is poorly suitable for prediction
of a spatial dose distribution in an irradiated objects. For
example, at radiation sterilization a density and effective
atomic number of irradiated materials in some times is
less than for aluminum wedge, on the basis of which a
value of the Ep and Ea for an EB are obtained.
Essential expansion of procedure opportunities of
the dosimetric wedge and the stack can be established
due to integration of computer modeling of a dose dis-
tribution in a film located in a wedge and stack made of
an arbitrary materials, processing methods and the com-
parative analysis of calculated with experimental re-
sults.
The software ModeDW (Modelling of Dosimetric
Wedge) and ModeStEB (Modelling of Dosimetric
Stack) are the special modules of information system
RT-Office 3 which are used for computer modeling of
dosimetric devices [6,7]. Software ModeDW is intended
for modeling an EB dose distribution in dosimetric film
placed along the sloping surface between the two
wedges made of an arbitrary materials. Software Mod-
eStEB is intended for modeling an EB dose distribution
in a stack of plates of an arbitrary materials interleaved
with dosimetric films or a stack of dosimetric films
alone. The dosimetric wedge and stack irradiate with
scanned EB on industrial radiation facility that is based
on the pulsed or continuous type of electron accelerators
in the electron energy range from 0.1 to 25 MeV.
2. GEOMETRICAL MODEL OF EB FACILI-
TY AND IRRADIATED PRODUCT
Schematic representation of the EB facility used for
simulation of the electron depth-dose distributions in the
dosimetric stack with dosimetric films irradiated with
scanned EB and on moving conveyor is shown in Fig.1.
Dosimetric stack consists of a set of plates made of
an arbitrary materials interleaved with dosimetric films
or a stack of dosimetric films alone. The number of
plates with dosimetric films in the stack are in the range
from 1 to 60. The plates of stack with dosimetric films
should be located on the conveyer platform perpendicu-
lar relatively incident EB axis.
Fig.2 demonstrates the geometrical model of dosi-
metric wedge irradiated with non-diverging EB on mov-
ing conveyor.

Simulation of EB dose distributions in an irradiated
films located in the wedge and stack was accomplished
by the MC method in a tree-dimensional (3-D) geomet-
rical model by the programs ModeDW and ModeStEB.
In accordance with the schematic representation of elec-
tron beam facility and heterogeneous target presented in
Figs.1,2 a source of electron beam including spectral
characteristics, a scanner, a conveyor line, an irradiated
target are considered as uniform self-consistent geomet-
rical and physical models.
3. PHYSICAL AND SIMULATION MODEL
3.1. PHYSICAL MODEL OF AN IRRADIA-
TION PROCESS
The physical model of an irradiation process for EB
radiation technologies includes the following principal
elements: EB irradiator characteristics, the systems pa-
rameters which provide the necessary spatial character-
istics in radiation processing, radiation and physical
characteristics of irradiated product. Besides, the set of
processes of interaction of ionizing radiation with prod-
uct which are necessary for description of results with
the established accuracy are included in physical model
at the theoretical analysis and/or computer modeling of
ionizing radiation expose on product.
In the physical model the parameters of an EB irra-
diator, an irradiation system, and an irradiated object as
Input data for the programs ModeDW and ModeStEB
are the following: Parameters of electron beam: average
beam current, or pulse duration and repetition frequency
in pulsed accelerators, electron spectrum, beam diame-
ter and spatial distribution of the beam intensity, angular
distribution of electron beam at the outlet of a scanning
system. Parameters of scanning system: modes of oper-
ation, the triangular or non-diverging irradiation of tar-
get; form of current in magnet of scanning system; repe-
tition frequency of scanning; parameters of the exit win-
dow for electron beam. Parameters of conveyor line:
speed and geometrical characteristics of the line. Pa-
rameters of irradiated product: geometrical characteris-
tics of the irradiated product; elemental composition of
the target; material and size of the covering for irradiat-
ed product. Regimes of target irradiation: one-, two-sid-
ed irradiation.
The following processes of interaction of an EB
with material and their modeling conceptions were in-
cluded in the physical model:
• electrons lost energy by two basic processing: in-
elastic collisions with atomic electrons and
bremsstrahlung;
• inelastic electron collisions with atomic electrons
lead to excitation and ionization of the atoms along
the path of the particles (model of grouping of the
transferred energy);
• emission of the secondary electrons (model of the
threshold energy);
• electrons participated in elastic collisions with
atomic nuclear lead to changes in the electron di-
rection (model of grouping of transferred pulse).
In the energy range of incident electrons from
100 keV to 10 MeV and irradiated materials with atom-
ic number Z 30, the model uncertainty is less than 5%≤
for calculated dose and charge depositions in the field of
the basic EB energy absorption.
3.2. MATHEMATICAL AND COMPUTER
METHODS OF CALCULATION
The developed software use a combination of two
methods for calculation of an absorbed dose in an object
irradiated by electrons: the formulas of semiempirical
models and simulation of transport of electron and gam-
ma radiation by a MC method. The features of a pro-
gram realization are the use of the following methods:
1. Method of a randomization of EB scanning pro-
cess is used for an effective evaluation of productivity
of the calculation scheme at the set parameters of an ir-
radiation process and a choice of statistics for MC simu-
lation which ensure a required statistical error for simu-
202
lation results.
2. Method of object translation. This new method is
intended for the effective solution of non-stationary
tasks in which desired quantity is the integral on a pro-
cess time. The problem of a dose calculation in an irra-
diated object after its passage through an irradiation
zone (travel or crossing through a zone) falls into such
class of tasks.
3. Optimization of model parameters of calculation.
The uncertainty of modeling results essentially depends
on values of the adjusting parameters for used models of
interaction processes of radiation with materials. There-
fore, in the computation scheme the model parameters
of simulation are chosen according with geometrical
and physical characteristics of an irradiation process to
minimize the run time for obtaining simulation results
with the established accuracy. For optimization of mod-
el parameters the adaptive algorithm on the basis of
semiempirical formulas is used [8].
The 3-D dose distribution in an irradiated dosimetric
films located in the wedge and stack is represented as a
function of two coordinates: the film width along the
scan direction (axis Y), and the film length along con-
veyer motion (axis Z), the dose value integrated along
film thickness (axis X).
Modeling of EB transport from the outlet window of
accelerator to the incident surface of the irradiated target
takes into account scattering of electrons in an air gap.
The requirements for computer modeling were chosen
so that in selected range of absorbed doses the relative
root-mean-square statistical error was less than 1%.
The software ModeDW and ModeStEB provides the
end-user with: data sets in the graphic and tabular form
for an absorbed dose and charge depositions within the
dosimetric devices irradiated with a scanned EB; com-
prehensive comparative analysis of output data; cogni-
tive visualization of output data; decision of optimiza-
tion problems with using dynamic and statistical
databases; presentation of physical and operational char-
acteristics for radiation processing.
4. DESCRIPTION OF THE SOFTWARE
MODEDW AND MODESTEB
Developed software can be used for the following
problem tasks in radiation processing:
1. Determination of dependence of an absorbed dose
distribution in a film as function of: density and a chem-
ical composition of film material; width and thickness
of a film; geometrical arrangement of a film in a wedge
and stack; density and a chemical composition of a
wedge and stack materials; geometrical sizes of a wedge
and stack; an orientation angle of a wedge and stack rel-
atively to incident electron beam.
2. Examination of dependence of an absorbed dose
distribution in a film as function of: an EB current and
speed of a conveyer motion; an angular distribution of
electrons in a beam; a spatial distribution of electrons in
a beam; a width of EB scanning; an angular characteris-
tics of a scan process; a time sweep of the scanner; an
air gap between the scanner and a target.
3. The comparative analysis of visual and numerical
difference of the depth-dose distributions in a film for:
various parameters of calculation; various calculation
models; an experimental and calculated depth-dose dis-
tributions in a film.
The feature of the software ModeDW and Mod-
eStEB are the following:
1. Built-in tools for statistical analysis.
2. Built-in tools for uncertainties estimation of re-
sults simulation due to uncertainties of input data for ra-
diation facility.
3. Estimation of uncertainties for physical models.
4. Comparison Modulus for visual and a numerical
analysis of calculated and experimental data and for de-
cision of optimization tasks in radiation processing.
5. Built-in tools for processing of experimental dosi-
metric data and their comparison with simulation pre-
dictions.
The softwares have intuitively clear graphical inter-
face for the end-users with the following features:
1. Detailed decomposition of input data for main ele-
ments of source and target (including spectral character-
istics for irradiation source).
2. Two levels for entering of input data via configu-
ration files and manually.
3. Expert control for the range of input data and co-
ordination for the set of geometrical and physical input
data.
4. Compatibility of export an input data to different
modules.
5. RESULTS SIMULATION
Some results of simulation of an EB dose distribu-
tion in the PVC (polyvinylchloride) dosimetric films lo-
cated between stack plates are presented in Figs.3,4.
The comparison results for EB dose distribution in
the 1st, 4th and 7th PVC films layers located between
PS (polystyrene) plates are shown in Figs.3,a,b, c re-
spectively. Stack consists of 8 packages. Each package
includes 2 layers: PS with thickness 1 cm and density
1 g/cm3, and PVC film with thickness 0.026 cm and
density 1.3 g/cm3. Stack size is 10x10 cm along scan di-
rection and along conveyer movement. Stack is irradiat-
ed by a point beam of electrons with energy 10 MeV in
the stationary regime.
As it is seen from Figs.3,a,b,c, the form of EB dose
distribution has the cone form in each film layers. The
passage of the point EB through the multi-layer struc-
ture of the stack is characterized by the monotonous de-
creasing of EB energy and expansion of the cone base
diameter with increasing of layers number from an en-
trance surface of EB.
The comparison results for EB dose distribution in
the 1st, 4th and 6th PVC films layers located between
PE (polyethylene) plates are shown in Figs.4,a,b,c re-
spectively. The stack consists of 6 packages. Each pack-
age includes 3 layers: PE-PVC-PE, PE with thickness
0.5 cm and density 1 g/cm3, and PVC film with thick-
ness 0.1cm and density 1.3 g/cm3. Stack size is 20 cm
along scan direction and 10 cm along conveyer move-

ment. Stack is irradiated by the scanned non-diverging
EB with energy 10 MeV on moving conveyer.
Fig.3. 3-D view of the dose distribution in the PVC
dosimetric film in the 1st, 4th and 7th film layers
Analysis of simulation results for the EB absorbed
dose field formation in the multi-layer structure of the
stack irradiated with the scanned non-diverging EB
have shown that beginning with 2nd package, the value
of absorbed dose in PVC films near the interface of
package with air is reduced about in 20-40 percent on
the length from interface up to 4 cm in comparison with
the packages center (See Fig.4,a). This effect can be ex-
plained by the balance disruption of primary scattered
electrons near the interface of stack plates with air.
An appearance in the lowermost (6th) film layer of
the local maximum for dose distribution near interface
of film with air (See Fig.4,a) can be explained by the
lateral highlighting by the flux of primary electrons
scattered in air.
Together with dosimetric functions, the developed
software allow to investigate the mechanism of ab-
sorbed dose field formation in multi-layers targets.

dosimetric film in the 1st, 4th and 6th film layers
CONCLUSIONS
The developed software essentially expands oppor-
tunities of the further development and usage of a pro-
cedure of the dosimetric wedge and the stack, because it
remove the restrictions on obtaining of experimental
data only in conditions when the flat one-dimensional
case of an EB irradiation is realized.
1. Software allows to develop optimum construc-
tions of the dosimetric wedge and stack for monitoring
of operational characteristics for EB. (on the basis of the
analysis of sensitivity procedure of the dosimetric
wedge and stack).
2. Software allows to extract the maximal possible
information on characteristics of the irradiation process
with scanned EB on the basis of the comparative analy-
sis of calculated and experimental results.
3. Software allows to develop the optimum phantom
of an object irradiated with EB for the experimental
testing of selected modes of an irradiation.
204
The softwares allow to determine a dose map in an
irradiated materials, a dose uniformity ratio, an energy
of incident electrons, an EB ranges, prediction and anal-
ysis of the EB absorbed dose characteristics related with
parameters of EB radiation facility, as well as an inter-
pretation of experimental dosimetry results. In the field
of EB radiation processing the programs can be used for
commissioning of EB facility, EB facility qualification,
process validation and routine process control.
