non-proliferation in Kazakhstan\" for the1st year of work.**

(Project \"Navruz\")

# Introduction

The international project \"Navruz\" is aimed at increase of
transparency of Central Asian states in nuclear sphere and consolidates
4 countries: Kazakhstan, Uzbekistan, Kyrgyzstan and Tajikistan. Sandy
National Laboratory and Energy Ministry of the USA assist the project.
The project representative on behalf of Kazakhstan is INP NNC RK.

The core of the project is ecological and radiation monitoring of
Amudarya and Syrdarya rivers, which waters belong to all the enumerated
participant countries. Duration of works on the project -- 2 years. Each
country on its side determined 10-15 checkpoints. Twice in a year, in
spring and in autumn, on these points there are planned field
investigations and sampling of environmental objects (water, soil,
bottom sediments, and vegetation) for further laboratory investigations.
Controlled parameters of the studied objects are natural and artificial
radionuclids (^226^Ra, ^228^Th, ^210^Pb, ^137^Cs, ^90^Sr, ^239^Pu,
^241^Am and etc.) and toxic dopes (U, Pb, Se, Sb, As, Be and etc.). As
executors of analytical works there are assigned two organizations: INP
NNC RK (Kazakhstan, c. Almaty) and INP SA UR (Uzbekistan, c. Tashkent).

The right for selection of sites for the rivers monitoring on the each
participant country territory is presented to organization, responsible
for realization of the Project on behalf of that country.

NNC RK Institute of Nuclear Physics as a result of thorough
consideration of all geographical, geological, industrial and economical
aspects, related to Syrdarya river and its environment, as well as after
discussion of specific geological matters with specialists on uranium
exploring and mining (Industrial corporation \"Volkovgeologiya\") has
offered the following 15 checkpoints, for inclusion to radiation
monitoring system:

14. [Syrdarya river]{.underline}, Kazalinsk town (upper), Baikozha
    village.

15. [Syrdarya river]{.underline}, Kazalinsk town (lower), Karlan
    village.

These points provide (in comparison with point 2) total effect control
of all situations and forms of activity connected with Syrdarya river.

The offered scheme was viewed and adopted on the project work meeting in
the city of Tashkent (August 2000). In this meeting there were viewed
and approved the main objects and top-priority tasks of the Project.

In the present report there have been presented results of analytical
investigations, obtained by INP NNC RK during the first year of the
Project realization. There is also presented a preliminary
interpretation of these results. Final conclusions will be presented by
the end of the second year, on the ground of data on analysis of
environmental objects selected within all four expeditions.

# Experimental part

# Methods and facilities

In the present work for study of environmental objects compound, there
were mainly used methods of instrumental (gamma-spectrometric)
radionuclid analysis and instrumental elemental (activation and
X-ray-fluorescent) analysis. There is given a short description of these
methods.

Radionuclid analysis.

For determination of a radionuclid compound there was used a gamma
spectrometric method, based on gamma radiation measuring of investigated
samples. The measurements were conducted on three, with different
parameters, semiconductor detectors. Detector characteristics are given
in the Table 1. Measurement time of each sample made up from 3 to 30
hours.

Wide-range and planar detectors have thin intake windows made of soft
low gamma radiation absorbing material (beryllium and all-carbon
composite respectively). This peculiarity allows efficient determination
of radionuclids on their relative soft gamma lines, for example, 210Pb
on 46.5keV line and 234Th on 63.3keV line.

The selected for analysis samples of soil and bottom sediments have been
dried and homogenized by milling up to the size of 150-200 micron in a
ball mill and by quartering of the obtained material there have been
selected analytical subsamples of 200gr. mass. Prior to measuring, the
subsamples have been placed into Petri cups with diameter of 70mm, with
bottom made of polyethylene film of 100 microns thickness. Water samples
have been evaporated up to obtaining of dry radicals or strong brine and
packed in fluoroplastic ditches with capacity of 25 ml and fluoroplastic
bottom with thickness of 100 micron. All samples for measuring have been
placed directly on detector intake window. The measured specters have
been treated by software package for gamma spectrometric analysis,
successfully used and tested during last several years, developed by the
laboratory members. In this package, in particular, there was the
treatment program of complex gamma and X-ray specters, using algorithm,
based on nonlinear method of the smallest squares and analytical
description of the line apparatus form. This method at the present
moment assures minimally possible fault at determination of full uptake
peak area and consequently maximal analysis sensitivity. Another program
of the indicated package allowed calculation of gamma radiation
registration total efficiency depending on geometrical sizes, detector
sample material and possible between them absorbents. After
determination of evaporated water sample activities there were
introduced to the results amendments, taking into account concentration
degree.

There have been calculated activities of radionuclids from three natural
families -- uranium, thorium and actinouranium and activity of natural
radionuclid ^40^K and artificial radionuclids ^137^Cs, and ^241^Am,
conditioned by global fall-outs after nuclear tests and Chernobyl
accident. List of determinate nuclides ended by those nuclides, which
had a quantum yield not less than 1-5%. In the Table 2 there are
presented characteristics of determinate nuclides. As it is seen from
the table, some of nuclides had more than one sufficiently intense gamma
lines. In these cases at calculations there was used a weight-average
activity value, at that as weight of each value, included in
calculation, there were taken reverse activity values of fault squares
of activity determination.

\*- value of ^208^Tl quantum yield is given by taking into account 36%
branch for convenient comparison of its activity with parent nuclide and
daughter nuclide.

At analysis of obtained results each of natural radionuclids families
was divided into several subfamilies, inside of which determinate
nuclides should be in the state of equilibrium even at natural and
man-caused redistribution, conditioned by physical-chemical processes in
soil and water. This equilibrium is conditioned by little period of
half-decay, not exceeding time in several months or years. Examples of
such groups are ^214^Pb and ^214^Bi from uranium family, ^212^Pb,
^212^Bi and ^208^Tl from thorium family and ^227^Th, ^223^Ra, ^219^Rn,
^211^Pb and ^211^Bi from actinouranium family. Activity parity of each
of radionuclids inside of each such subfamily should indicate on the one
hand to conducted analysis correctness and on the other hand, give more
objective bases for comparison, for example of two progenitors of
different subfamilies from the sight of their equilibrium.

**[Neutron activation analysis.]{.underline}**

Elemental analysis of bottom sediments samples and dry water remainders
was conducted by neutron activation analysis (NAA). Preliminary
preparation of bottom sediment samples and water consisted of drying and
abrasion of dry samples in a porcelain mortar.

From prepared sample by quartering there were selected analytical
subsamples of 0.2 gr. For NAA the selected subsamples were packed in
double polyethylene packets and aluminum container and irradiated in the
nuclear reactor. In the same container there were placed nichrome
comparators for determination of neutron fluence and specter at
irradiation. Irradiation of samples during three hours was conducted in
the WWR-K reactor central channel, heat rating of reactor made up
300kVt, at that the neutron flux on the spot of irradiation made up n
10^12^ neutron cm^-2^ s^-1^. The irradiated samples after 4 day
\"cooling\"and repacking were delivered for measuring.

Measurements have been conducted on semi-conducting gamma-spectrometers
of LNPAM (laboratory of nuclear-physical analysis methods) with
germanium detector GEM-20180 (certificate on State control #4-016/0-415
dated 26.01.99). During the first measuring performance there were
determined: Na, K, Ca, As, Br, Cd, Sb, La, Sm, Au, U. The second
performance of measuring was conducted in 30-32 days. In these measuring
there were determined: Sc, Cr, Co, Fe, Zn, Se, Rb, Cs, Ba, Eu, Tb, Yb,
Hf, Ta, Hg, Th. Simultaneously with work samples there were measured
nichrom comparators and standard samples: SGD-1a, Sl-1, TM-2a, GXR-1,
GXR-5, irradiated in the same container. Calculation of the element
concentration was fulfilled on the measured activities of analytical
isotopes, nuclear-physical parameters (activation section, half-decay
period, quantum yield of gamma-radiation) and flow data and neutrons
specter, calculated from results of comparators measurements.

**[X-ray fluorescent analysis.]{.underline}**

X-ray-fluorescent analysis method (XRFA) was used as one of methods for
characterization of an elemental compound. At analysis of soil, bottom
sediments and dry water remainders samples after evaporation was used
XRFA with isotope excitation. As excitation source there was used
isotope 109Cd with activity of approximately 3mKi. For registration of
X-ray radiation of the analyzed elements and back scattering radiation
of excitation source there was used Si(Li) detector with an active
surface of 80mm^2^ and resolution on line of 5,9keV 180eV. Intake
detector window was made of beryllium with thickness of 25 micron. At
the indicated characteristics of spectrometric cluster and 30-minute
exposition the method allows simultaneous determination of approximately
15 elements with sensitivity from hundreds and tens to units and
portions of mkg/gr. Most of the elements were analyzed on K-series
characteristic X-ray radiation lines, except lead, which were determined
on L-series lines. Analysis samples passed standard preparation,
including drying and homogenization and were placed in 10ml. ditches
with bottom of polyethylene of 100 micron thickness. The ditches for
analysis were disposed on a special holder containing excitation source.
The holder construction assured protection from direct source radiation
on the one side and minimized distance between sample and detector
intake window from the other side. A special program, developed by the
laboratory members treated the selected specters. For calculation of
matrix effect there was used a back scattering radiation of excitation
source. For calculation of selective absorption by elements with
significant concentrations (approximately 10000mkg/gr. and higher) there
were introduced special amendments. The analysis correctness was many
times tested on IAEA comparison samples during several last years.

**The results and their discussion.**

By potentiometric analysis method (standard methods) there was carried
out determination of minor- and major elements in samples of water
selected on Kazakhstan territory within the 1^st^ and 2^nd^ expeditions.
The results are presented respectively in the tables 3 and 4. Comparison
of table data indicated on higher concentration of water components in
winter than in spring. The greatest water mineralization corresponds to
P3 and 4 (Sary-Agach resort).

By method of X-ray-fluorescent analysis there was determined
micro-compound of bottom sediment and soil samples selected on
Kazakhstan territory (1^st^ and 2^nd^ expeditions), Uzbekistan (1^st^
expedition), Kyrgyzstan(1^st^ expedition) and Tajikistan(1^st^
expedition). The results are presented in tables 5-9, respectively.
Comparison of obtained with values of \"average concentrations for
sediment rocks\" indicates on high concentrations of calcium in all
studied samples of soil and sediments.

By method of neutron-activation analysis there was determined compound
of micro-dopes (and definite micro-dopes) in samples of water, bottom
sediments, soil and vegetation, selected on Kazakhstan territory during
the 1^st^ expedition. The results are presented in the tab.10-12,
respectively. The obtained data indicated on very high content of
selenium in all studied objects. Concentration of this element in water
arouses alertness as it exceeds health sanitary standards of maximal
tolerant concentration (MTC-1mkg/l) for drinking water by 1.5-4 times.
In some water samples there are noted high concentrations of definite
elements: P13-Fe (940 mkg/l), Ag(0,713mkg/l), Th(0.13 mkg/l); P4-Hg(0.4
mkg/l); pp5 and 6-Re(0.7-1.4 mkg/l). The largest concentration of
micro-dopes in bottom sediments corresponds to P1, what can be related
to their import with water from neighboring countries. Also one can note
significant concentration of As in bottom sediments and soil in the
proximity of industrial center of Shymkent town (PP4 and 5).

There was conducted a radionuclid analysis of environment objects,
selected within the first expedition on the territories of all
countries: Kazakhstan (water, soil, bottom sediments), Uzbekistan (soil,
bottom sediments), Kyrgyzstan (water, soil, and bottom sediments).
Tadjikistan (soil and bottom sediments). The results are presented in
the tab.13-22, respectively.

On table data there was made a graphic structure of natural radionuclids
distribution in soil and bottom sediments along Syrdarya riverbed on
Kazakhstan territory. The results are presented in the tab1. It is seen
that the largest concentration of natural radionuclids in bottom
sediments matches up to eastern part of Chardara reservoir (point 1).
Probably the reason of this is hydro-geological and landscape properties
of this place, contributing to redistribution of radionuclids from water
to bottom sediments. Mechanism of uranium deposits industrial
engineering effect in headstreams of Syrdarya river (Uzbekistan,
Tajikistan, Kyrgyzstan) is also could be taken into account. There are
legibly distinguished with the increased concentrations of all natural
radionuclids the point 9(soil) and points 10, 11(bottom sediments) --
uranium deposits near Shieli town.

Radionuclid compound comparison of bottom sediments in vicinity (upper
and lower with stream) of big towns Saryagash (points 3 and4), Kyzylorda
(points 11 and 12) indicates on significant decrease of content level
(30-50%) in lower courses. One can assume that those technical
facilities on river at these towns serve as distinctive barriers for
further distribution of radionuclids.

On Uzbekistan territory the highest content of natural radionuclids in
soil and bottom sediments is detected in samples selected on 7, 8 and
points. In these samples concentration of radionuclids of ^238^U and
^232^Th families frequently exceeds 100Bq/kkg.

On Kyrgyzstan territory the highest content of natural radionuclids of
^238^U and ^232^Th families in soil matches up to the point 1. It is
necessary to note that on the territory of this country there was
revealed place with the highest content of ^137^Cs artificial
radionuclids in soil (point 5-38Bq/kg.).

The highest concentration of natural radionuclids (up to 100Bq/kg) in
^238^U and ^232^Th families of Tajikistan soil matches up to the points
3, 4,5 and 14. On this country we can also note the highest
contamination by artificial ^137^Cs radionuclid (average content in soil
-- 6.7 Bq/kg).

along

Syrdarya river bed (a-in soil, b- in bottom sediments)

Besides the enumerated analytical investigations in a reporting year
there were conducted analyses of definite soil, bottom sediments and
water samples by mass-spectroscopy, as well as AES-ICP and ICP-MC. The
obtained results and their interpretation, in combination with the other
data analysis, will be presented in the final report, after completion
of the second year work on the Project.

# Conclusion

The first results of analytical investigations obtained on International
project \"Navruz\" allowed conducting of preliminary evaluation of
radiation and ecological situation in definite regions of the Project
participant countries and revealing a number of peculiarities at
distribution of radionuclids in Syrdarya and Amu-Darya rivers
watersheds.

On the whole investigated region there was revealed high concentration
of selenium. Content of this element in Syrdarya river water notably
exceeds norm of maximal tolerant concentration for drinking water.

Radionuclid analysis data allowed revealing in each participant country
the most contaminated by natural radionuclids areas.

Duration of the Project works will give an idea of radiation situation
dynamics in Syrdarya and Amu-Darya rivers watersheds.
