2. Accidents from
experiments
Bad effects in the environment

3. Chernobyl
The Chernobyl disaster was a
catastrophic nuclear accident that
occurred on 26 April 1986 at the
Chernobyl Nuclear Power Plant.An
explosion took place and fire released
large quantities of radioactive
particles into the atmosphere, which
spread over much of the western
USSR and Europe.

4. The environmental effects
Groundwater
Radionuclides with short half-lives
decayed away long before they could
affect groundwater supplies.
Longer-lived radionuclides such as
radiocaesium and radiostrontium
were adsorbed to surface soils before
they could transfer to groundwater.

5. The environmental effects
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”.

6. Toxic algae
The last few years there
has been an issue which
concerns many scientists in
the area of the
Mediterranean sea. From
the 1926 there have been
two new kinds of algae in
the sea. Scientists of
course noticed them a bit
later.

7. It was determined that the first one
was leaking out from the exhibition
aquarium of Monaco by accident and it
is called CaulerpaTaxifolia.
The second one which is called
Caulerpa Racemosa, has escaped from
the Red Sea.

8. These two kinds of algae are considered a
threat to our environment because they are
spreading extremely fast and because of they
structure they cover every other kind of sea
plant that is in their way. So the consequences
are decrease of the biodiversity in the sea and
overturn of the ecological balance.

9. Nevada’s Atomic bomb
In 27 January 1951 at a dry
lakebed in Nevada the first air
dropped nuclear device was
dropped for testing purposes.
This test was a part of an
American nuclear test series
called Ranger which was
consisted of five air dropped
nuclear tests.

10. In the 1963 an agreement which banned all
nuclear tests in the atmosphere, underwater and
in outer space was voted because of the obvious
effects of radioactivity in people’s health. Until
today the scale of harm is uncertain.

11. Bhopal
On 3 December 1984, a
Union Carbide India
Limited pesticide plant in
Bhopal leaked around 32
tons of toxic gases which
led to the worst industrial
disaster to date.

12. The impact of the disaster
They continue to this day in
terms of psychological and
neurological disabilities,
blindness, skin, vision,
breathing, and birth disorders.
The soil and ground water
near the factory site have
been contaminated by the
toxic wastes.

13. Tokaimura nuclear accident
Tokaimura nuclear accident indicates the nuclear disaster which
occurred on 30 September 1999, resulting in two deaths.

14. Effects
• Dozens of emergency
workers and nearby
residents were
hospitalized
• Hundreds of thousands of
others were forced to
remain indoors for 24
hours;

15. Effects
• 39 of the workers were
exposed to the radiation.
• At least 667 workers,
emergency responders
,and nearby residents
were exposed to excess
radiation as a result of the
accident.
