We have read
about ghost towns in novels – at least one exists in reality for 28 years now
after that fateful day of 26th April 1986. An explosion in the core dispersed large
quantities of radioactive fuel and core materials into the atmosphere and ignited the combustible graphite
moderator. The burning graphite moderator increased the emission of radioactive
particles, carried by the smoke, as the reactor had not been encased by any
kind of hard containment vessel. The accident occurred during an experiment
scheduled to test a potential safety emergency core cooling feature, which took
place during a normal shutdown procedure.
That disaster endangered hundreds
of thousands of lives and contaminated pristine forests and farmland with
deadly radiation – putting fear on humanity in many other projects. The blast on April 26, 1986, spewed a cloud
of radioactive fallout over much of Europe and forced hundreds of thousands
from their homes in the most heavily hit areas in Ukraine, Belarus and western
Russia. A 19-mile area around the plant has been uninhabited except for
occasional plant workers, and several hundred local people who returned to
their homes despite official warnings.

The Apr 1986
disaster is – ‘Chernobyl disaster’ a
catastrophic nuclear accident that occurred at the Chernobyl Nuclear Power
Plant in Ukraine (then officially the Ukrainian SSR), which was under the
direct jurisdiction of the central authorities of the Soviet Union. The Chernobyl disaster was the worst nuclear
power plant accident in history in terms of cost and casualties, and is one of
only two classified as a level 7 event (the maximum classification) on the
International Nuclear Event Scale (the other being the Fukushima Daiichi
nuclear disaster in 2011). The disaster
began during a systems test on Saturday, 26 April 1986 at reactor number four
of the Chernobyl plant, which is near the city of Pripyat and in proximity to
the administrative border with Belarus and the Dnieper River. There was a
sudden and unexpected power surge, and when an emergency shutdown was
attempted, an exponentially larger spike in power output occurred, which led to
a reactor vessel rupture and a series of steam explosions. Russia, Ukraine, and
Belarus have been burdened with the continuing and substantial decontamination
and health care costs of the Chernobyl accident.
Time has
effectively stood still in the Ukrainian city of Pripyat, which was evacuated
in the aftermath of the 1986 Chernobyl nuclear explosion. It is stated that at the
time of the disaster during the Soviet era, about 49,000 people lived in
Pripyat, located less than two miles from the Chernobyl Nuclear Power Plant.
They left behind schools, homes, factories, parks and gyms that have remained
largely undisturbed for the past 30 years.

While one
would only have read largely negative reports on the disaster, here is a
different one, read in Mail Online of 1st Dec 2014……. It is about a Brown
bear pictured in Chernobyl for first time in a century and it says – ‘ Nuclear
disaster creates wildlife haven thanks to total absence of human life for 30
years’
A brown bear has been
spotted in the disaster zone around the Chernobyl, the first time one has been
seen in the area for 100 years. The bear was photographed by an automatic
camera trap in the exclusion zone around the Ukrainian nuclear power plant, the
scene of one of the world's worst nuclear accidents. Scientists are studying
the area, evacuated since the reactor meltdown in 1986, to better understand
the risks radioactivity poses to humans and wildlife. It is far from the first
large mammal discovered to be stalking the 30km-radius Chernobyl Exclusion
Zone. Dr Gaschak's camera's have already spotted lynxes, grey wolves, wild
boar, elk, horses and otters, among other animals, living in the deserted area.
Project leader Mike Wood
from the University of Salford told BBC News: 'We are basically working on the
assumption that as you move people out of the equation and human pressure and
disturbance is removed, then any animals that have a corridor into the
exclusion zone find they are suddenly away from the pressures and dangers
presented by people.' More than 100,000 people were evacuated from their homes
around the damaged Chernobyl power station after the April 1986 reactor
explosion - the worst nuclear accident until the meltdown at Fukushima Daichi
in 2011. The TREE research programme aims to 'reduce uncertainty in estimating
the risk to humans and wildlife associated with exposure to radioactivity and
to reduce unnecessary conservatism in risk calculations.' It combines
controlled laboratory experiments with fieldwork, most of which is planned for
the Chernobyl Exclusion Zone.
The researchers will be
focusing on three different areas of different levels of contamination to get a
comprehensive overview of what species are found in the exclusion zone. At any
one time 15 cameras will be operating in each area to catch a glimpse of the
kinds of wildlife there. This first stage of the project will continue until
late 2015. 'Once we have completed this particular stage of the study, looking
at what animals are there and in what density, we are then going to be
selecting one particular species to target for a trapping and collaring
campaign,' Dr Wood told the BBC. 'We will be fitting collars with GPS to these
animals, and also dose-measurement technology so that we are then able to track
movement over the course of a year through the exclusion zone and get a real measurement
of the exact radiation exposure that these animals get.'
If you are
wondering why Maria Sharapova got a mention in this post - since Feb 2007, she has been a United Nations
Development Programme Goodwill Ambassador, concerned specifically with the
Chernobyl Recovery and Development Programme.
