8. Exactly twenty five years ago, in April 1986 this
terrible word has sounded on all planet, having
announced to the world the biggest accident of the
XX-th century – explosion on 4 power unit of the
Chernobyl NPP, carried away lives of ten thousand
people. This day we have realized that the atom
can be not only peace…
9. On the 26-th of April 1986, at 01:23 reactor
four suffered a catastrophic power increase,
leading to explosions in its core.
10. An explosion and fire released large quantities
of radioactive contamination into the
atmosphere, which spread over much of
Western USSR and Europe.
11. The attempted experiment
The accident occurred during an experiment
scheduled to test a potential safety emergency
core cooling feature, which took place during
the normal shutdown procedure.
12. Rough infringements of service regulations of
the atomic power station, made by its personnel,
are the following:
•Experiment carrying out "at any cost", despite
change of a condition of the reactor;
•The conclusion from work of serviceable
technological protection which simply would stop the
reactor still before it has got to a dangerous mode;
• Hushing up of scale of failure in the first days
management CNPP.
13.
14. The bulk of the work was carried out in 1986-
1987, were attended by approximately 240 000
people. The total number of liquidators
(including following years) was about 600 000.
15. The radiation levels in the worst-hit areas of
the reactor building have been estimated to be
5.6 roentgens per second, equivalent to more
than 20,000 roentgens per hour. A lethal dose
is around 500 roentgens over 5 hours, so in
some areas, unprotected workers received
fatal doses within minutes.
16.
17. Evacuation developments
Announcement for the evacuation of Prypiat.
The evacuation began at 14:00 on 27 April.
In order to expedite the evacuation, the
residents were told to bring only what was
necessary.
18. From 1986 to 2000, more than 350 000 people
were evacuated and resettled from the most
severely contaminated areas of Belarus ,
Russia and Ukraine.
19.
20. Residual radioactivity in the environment
Rivers, lakes and reservoirs
The Chernobyl nuclear power plant
is located next to the Pripyat River,
which feeds into the Dnipro River
reservoir system, one of the largest
surface water systems in Europe.
21. Groundwater
Groundwater was not badly
affected by the Chernobyl
accident since radionuclides
with short half-lives decayed
away long before they could
affect groundwater supplies.
22. Flora and fauna
After the disaster, four square kilometers of pine forest
directly downwind of the reactor turned reddish-brown
and died, earning the name of the "Red Forest".
23. Mutations in both humans and other animals
increased following the disaster.
24. In the aftermath of the accident, 237 people
suffered from acute radiation sickness, of whom
31 died within the first three months.
