Forty Years of Nuclear Contamination in Chelyabinsk, Russia
Abstract
Chelyabinsk was one of the former Soviet Union's main
military production centers, which included nuclear weapons
manufacturing. Accidents, nuclear waste disposal and day to
day operation of the Mayak reactor and radiochemical plant
contaminated a vast area of the province. In the early 1950s
there were so many occurrences of death and disease from
the nuclear waste dumping in the Techa river that 22 villages
along the river banks in a 50 kilometers zone downstream
from Mayak were evacuated. In 1957, a nuclear waste storage
tank accident released radiation double the amount released
by the Chernobyl accident. This accident was kept secret and
10,700 people were evacuated. The severe environmental
contamination of this region led to dramatic increases in
cancer rates, birth defects, and sterility. Over the past 33 years,
there has been a 21% increase in the incidences of cancer,
25% increase in birth defects and 50% of the population of
child bearing age are steifle.
Cause of the Environmental Crisis
During World War II, Chelyabinsk was one of the Soviet
Union's major armament production centers. Entire factories
on the western side of the Urals were taken apart and
reconstructed on the other side of the Urals, the Chelyabinsk
province. Chelyabinsk had one of the largest tank factories in
the country, as well as one of the major nuclear armament
plants. Due to these "strategic industries" the province was
closed to visitors until 1989. Following the political and
economic transformation in Russia, the tank factory now
produces tractors, and the Mayak nuclear armament plant is
trying to evolve into a fast breeder recycling plant for foreign
spent-plutonium (nuclear wastes).
The Mayak nuclear complex was one of the Soviet Union's
main military production centers. During the last fifty years
this complex has contaminated the Chelyabinsk region with
highly dangerous nuclear and chemical wastes. The following
is a chronological listing of the practices and accidents that
caused the environmental crisis:
1949 to 1956: Liquid wastes from the Mayak nuclear
complex were dumped into the Techa-Iset-Tobol
river system
From 1949 to 1956, medium and high-level radioactive liquid
wastes were dumped into the river system Techa-Iset-Tobol.
During this period about 76 million m(3) of radioactive wastes
were released into the Techa river. Over 124,000 people
living along the banks of the river system were exposed to radiation.
Protective measures finally began in 1956 when hydrological
engineering measures aimed at immobilizing deposited
radioactive substances in the upper reaches of the river were
implemented. The river system is currently in the process of
a natural deactivation that will take a few hundred years. The
water downstream is nearly free of excess radioactive
cesium, however the river bed sediment and the riverbanks
still contain high levels of cesium and strontium.
1957: Explosion of a nuclear waste storage tank at
the Mayak nuclear complex
On September 29,1957 a liquid radioactive waste storage tank
exploded following a failure in the cooling system and
polluted an area equal to the size of New Jersey with
plutonium and strontium. The explosion formed a radioactive
cloud over the provinces of Chelyabinsk, Sverdlovsk and
Tyumen. A total area of 23,000 sq. kilometers was
contaminated and the area is now called the East Ural
Radioactive Trace, the EURT. This accident was kept secret
from the outside world for military safety reasons and 10,700
people were silently evacuated. This nuclear accident released
twice the amount of curies that were released by the
Chernobyl accident.
1967: The Lake Karachay accident
Two self-contained natural lakes near the plant were chosen to
divert waste dumping in the river-system - lake Karachay for
high-level waste and lake Staroe Boloto for medium level
waste. During the long, hot summer of 1967, lake Karachay
dried up and radioactive waste from the exposed lake blew
over an area of 2,200 sq. kilometers. Other accidents,
irresponsible nuclear waste disposal and day-to-day
operations of the Mayak nuclear-chemical facility have
contaminated an area with a diameter of 400 km.
In addition to pollution from the nuclear complex, the
metallurgical industry has heavily contaminated this region.
The Ural mountains are rich in iron ore, chromium, copper
and nickel and the region has an enormous metallurgical
industry. The amount of lead in the air in Chelyabinsk city is
equal to the total amount of lead pollution in the Netherlands
(population of 15 million) in 1982, before unleaded petrol
and catalytic converters were introduced. Any improvement
of quality in the Urals has been due to the economic
downturn and closing of factories. Hardly any investments
have been made by the government to reduce pollution levels.
Impact of the Environmental Crisis
Soon after the Mayak nuclear complex became operational,
death and diseases in the region increased dramatically due to
the dumping of medium and high level radioactive waste into
the river system. As a result, 22 villages on the riverbanks, in
a 50 km downstream zone from the complex, were evacuated.
The village of Muslyrnova, just outside the 50 km zone was
particularly contaminated, but it was never evacuated.
Muslyumova lies 45 km north west of Chelyabinsk city and
has 4,000 inhabitants. The village had no wells and until
recent years depended on the tiver Techa, for drinking water.
The villagers of Muslyumovo grew increasingly ill following
contamination of their water. The number of birth defects
and cancer deaths soared, but the authorities refused to take
remedial measures. Statistics show that gene-mutations in the
villages just outside the evacuated zone were 15 times the
average for the Russian Federation. The local authorities
attributed the high level of birth defects among newborns
and the high mortality rates to a low standard of living.
A report on the health of the people on on the banks of
the Techa River was published in 1991, which showed that the
incidence of leukemia increased by 41% since 1950. From
1980 to 1990, all cancers in this population rose by 21% and
all diseases of the circulatory system rose by 31%. These
figures are probably gross underestimations, because local
physicians were instructed to limit the number of death
certificates they issued with diagnosis of cancer and other
radiation-related illnesses. According to Gulfarida Galimova,
a local doctor who has been keeping records in lieu of official
statistics, the average life span for women in Muslyumovo in
1993 was 47, compared to the country average of 72. The
average life span of Muslyumovo men was 45 compared to 69
for the entire country.
Chelyabinsk regional hospitals were not allowed to treat the
villagers and they were sent to the Ural Centre for Radiation
Medicine. The medical data of the UCRM was classified until
1990. Records of the UCRM chart the decline in health of
28,000 people along the Techa and all of them are classed as
seriously irradiated. Since the 1960s, these people have been
examined regularly by public health officials.
According to the head of the UCRM clinical department the
rate of leukemia has doubled in the last two decades. Skin
cancers have quadrupled over the last 33 years. The total
number of people suffering from cancer has risen by 21%.
The number of people suffering from vascular diseases has
risen 31%. Birth defects have increased by 25%. Kosenko
carried out a small epidemiological study of 100 people
selected at random. From this group 96% had at least frve
chronic diseases (heart diseases, high blood pressure, arthritis
and asthma), 30% had as many as ten chronic conditions.
Local doctors estimate that half the men and women at child
bearing age are sterile.
Even today, the local population still does not know the actual
levels of radioisotopes in its home grown products. German
scientists who did a field study in Muslumova in 1996 have
measured some food samples in the villages and found
astonishing levels of radioactivity, 17,000 becquerrel per kg in
fish, and 8,000 per kg in vegetables (in Europe, products with
more than 600 bequerrel are taken off the market). Only since
1989, the villagers have started to get information about the
dangers of the radioactive contamination of their river.
After the 1957 storage tank accident, 10,700 people were
permanently evacuated from the EURT. Half of these people
were evacuated eight months after the accident These people
had been consuming contaminated food without restriction,
since the accident and until their evacuation. The Karachay
accident from 1967 affected 63 populated areas with a
population of 41,500 with 3.7 kBq/sq m (O.lCi/sq km) The
4800 residents nearest to the lake received an average dose of
13mSv. At the time of the Karachay accident, the
International Commission for Radiological Protection (ICRP)
had set the safe limit on radiation at 5mSv per year. At
present, the ICRP standard is lmSv per year.
According to the Russian Scientific Centre Kurchatov and the
Obninsk Institute of Radiology, a total of 437,000 people
have been affected by the three accidents at Mayak. Of the
total 437,000 people affected, very few were ever evacuated
from the area. Very often the evacuees were moved to areas
not far from the contaminated zone and the people continued
to use their gardens within the contaminated areas.
Other people exposed to elevated levels of radiation in
Chelyabinsk region are workers of Mayak, people living in the
districts in the vicinity of Mayak and participants during
cleanup and restoration activities. At the beginning of
operation of Mayak, the average annual exposures for reactor
workers and chemical plant workers was 940 mSv and
l,l3OmSv respectively. (At present, the ICRP safety standard
is lmSv per year.) The workers from Mayak lived in
Chelyabinsk-65 and Chelyabinsk-70, both closed cities
situated about 80 km from Chelyabinsk city, and close to the
Mayak complex. Chelyabinsk-65 and -70 were nicknamed
chocolate city, because these cities were among the few cities
in USSR where chocolate was available in abundance.
In the early 1990s, Ivan Druzhko, a Mayak plant official told
reporters from a US television show that he believed nearly
8,000 Mayak workers were exposed to doses exceeding
1,OOOmSv. L.A. Buldakov, deputy director of the institute of
biophysics in Moscow presented data on a conference in Paris
in 1991 that showed a total of 1,812 Mayak workers were
exposed to least 2,45OmSv over the period 1949-1954 and
another 1,286 people were exposed to at least 1,22OmSv.
These exposure levels are horrifying when you compare these
levels with the ICRP's present safety standard, which is 1mSv
per year. In the 1980s, Ural Medical Radiation Center started
registering diseases caused by radiation. In 1989 a booklet
was published stating that 935 workers at the Mayak complex
were suffering from chronic radiation syndrome. This number
later came down to 66 but was changed back to the former
figure after campaigns by local organizations.
While the rural communities in Chelyabinsk suffer from the
effects of radioactive contamination, the urban populations
face the effects of the chemical and metallurgical industries.
In 1994 the Chelyabinsk Provincial Institute for Public Health
and Environment did a survey on non-infectious diseases in
the cities of Karabash, Magnitogorsk, Chelyabinsk, Zlatoust,
Kopeisk and Miass. The survey showed considerable
increases of various diseases in the Chelyabinsk region. The
results from Karabash and Magnitogorsk were so bad that the
provincial Ministry for the Environment classified these cities
as ecological disaster zones. (SOE rep. P 195) Children from
Karabash were found to be considerably smaller than children
from the control group; they had 3.5 times more birth defects;
2.7 times more skin diseases; streptodermia 10 times more,
and 2.1 times more diseases of the digestive organs.
Cancer rates in the metallurgical district of Chelyabinsk are
four to five times higher than the Russian average. Children's
morbidity and mortality rates in the metallurgical district are
three times higher than the average for the city. Lead
intoxication from the metallurgical factories causes blood
diseases and brain damage. Chromium is another major
pollutant. U.S. studies have shown that the incidences of lung
cancer for chromium factory workers are 28 times than the
average rates. Workers barely survive until their retirement
age and male life expectancy has gone down to 57.
Statistics from the neighboring province of Ekaterinaburg
show that in the early 1990s the number of women workers
in the metallurgical and electrical engineering industry
doubled, and their numbers in light industry tripled. Statistics
in Chelyabinsk, if available, would probably show the same
trend. After the Soviet Union dissolved in 1991,
unemployment soared and Russia's social security system
became more and more insecure. Today, most women cannot
afford to lose their jobs and will keep on working as long as
possible. The women work even though the working
conditions badly affect their ovm health and their children's
health. Maternity leave with pay was well taken care for under
the Soviet system but now for fear of losing their jobs,
women keep silent about their pregnancy as long as possible-
Many women work more than one job. Apart from working
under very unfavorable conditions women also have to take
care of their families. Wages are low and poverty is increasing.
Even in the "workers paradise", as the former Soviet Union
was called, working conditions were not always favorable. In
the late 1980's, 20-50% of workplaces did not meet Soviet
standards. By the end of the Soviet era, 14.5 million women
worked in industry and 3.4 million, about one-fifth of them,
worked under hazardous conditions such as toxic fumes,
extreme high or low temperatures, and excessive noise and
vibrations.
Chelyabinsk has long been a region of strategic military
importance and has a history of secrecy. Even today it is not
easy to obtain environment or health information. Obtaining
information from independent sources is even more difficult.
Response to the Environmental Crisis
In 1992, Movement for Nuclear Safety (NNS), in co-
operation with local authorities, organized an international
conference on the consequences of nuclear industry in the
South Urals. This was the first time that the public gained
access to classified information concerning the health of the
population affected by radionucleides from the nuclear
military complex, Mayak. In the same year NNS began
campaigns to register people affected by nuclear
contamination in Muslyumovo. By the end of 1993 the
democratic process was interrupted and the co-operation with
authorities became less effective. By then, however, MNS had
obtained a large group of voluntary workers and support
from the local population.
During the 1995 UN Fourth World Conference on Women in
Beijing, Natalya Mironova of MNS met with Women in
Europe for a Common Future and partners in Uzbekistan and
the Ukraine and discussed setting up a joint project on
women, health and environment. In 1996, a project entitled
Women join Forces for Health and Environment, was
launched to better understand the health effects of the
environmental contamination in the Chelyabinsk region,
particularly effects on women and children. NNS offered
courses to women on healthy living and on strengthening
their immune system. The NGO also sponsored seminars on
how to reduce the effects of contamination of the human
body caused by bioaccumulation of radionucleides. Women
received information from a dietician and were taught how to
cook to retain vitamins.
MNS also started publishing a series of brochures titled
'Simple Answers to Complicated Questions,' on the immune
system and healthy food in a region contaminated with
radionudeides. The brochures were widely distributed among
the villages just outside the evacuated area near Mayak.
Together,with other NGOS, MNS has been campaigning for
resettlement of the village of Muslyumovo. In 1997 these
actions finally became effective: the province administration
decided to resettle the village. It is still unclear, however, when
this will happen and where the villagers will go. MNS is also
active in local politics and has been campaigning against the
development of plutonium recycling facilities at Mayak to
treat imported plutonium waste from abroad, particularly
from Germany and the U.S.A. MNS promotes sustainable
economic alternatives including energy-saving, alternative
energy sources and organic farming.
Recommendations for Action
Most of the information about plutonium contamination and
plutonium impacts is still classified, although plutonium
contamination has affected a geographical area 10 times larger
and 100 times more intensely than expected. Despite this, the
local administration is eagerly looking at potential revenues
from plutonium recycling. Plutonium recycling is not a
sustainable solution. Chelyabinsk needs assistance from the
international community to identify viable alternatives to
polluting industries.
When the Cold War ended Russian women wrote letters to
the UN asking for assistance and tried to force the Russian
authorities to listen to the voices of the NGO community.
The international community can support the fight for a
healthy and sustainable future by endorsing our demands to:
> Set up an international institution to set new health
standards for radiation protection, because 1950 standards
are no longer adequate or relevant;
> Disseminate information about the health effects of
the nuclear Industry;
> Support the Comprehensive Nuclear Test Ban Treaty and
make sure that victims get adequate compensation;
> Stop the export of nuclear waste;
> Collect data on environmental health problems;
> Promote research and development of medical
detoxification methods and promote the exchange of
knowledge on successful methods;
> Fund long-term epidemiological research in regions
adversely affected by environmental pollution; and
> Establish health care and health monitoring programs for
victims of environmental pollution and people living in
hazardous zones.
