The photos show a place                     On the 26th April 1986 a plant reactor
called Chernobyl                            exploded during a failed cooling
                                            system test, igniting a massive fire that
                                            burned for ten days. At 1:23am the
                                            reactor became out of control creating
                                            explosions and a fireball which blew
                                            off the reactor's heavy steel and
                                            concrete lid.




 The accident released radioactivity equivalent to
 400 times that of the Hiroshima bomb.

 More than 350,000 people were displaced and
 scientists estimate up to 90,000 square miles of
 land in Belarus, Ukraine, and Russia (all part of
 the Soviet Union at the time) were contaminated
 with unhealthy levels of radioactive elements.
So what?
Radioactivity damages our DNA and
changes our body’s cells. This causes
cancer and mutations.

Serious exposure to radiation is likely to
cause death within 2 to 4 weeks.

176 people were working at the reactor that
night. Most were killed instantly, others
died agonising deaths soon afterwards.

Many of those who didn’t die from the
exposure have gone on to give birth to a
mutated generation.

'I remember joking to the others, "There must
be an incredible amount of radiation here.
We'll be lucky if we're all alive in the morning."‘

- fireman Anatoli Zakharov (Shortly afterwards,
he was hospitalised in Kiev, where he
remained for two months)
How was the radioactivity
contained?

When the Chernobyl accident
occurred, the power plant was
covered in a massive concrete and
steel shell. That shell was meant
to last for 20 to 30 years.


Work is set to begin soon on a new
stadium-size shelter that will
confine the entire building and the
radioactive material within for at
least a hundred years. The project
is estimated to be completed by
2008.
Does the UK have any
Nuclear Power
Stations?

Yes. Some are due to be shut
down, such as Oldbury and
Sizewell A.
How is nuclear power made?

Uranium is usually the fuel (Plutonium could also be used). A uranium atom can
be split. This releases huge amounts of energy.

                                          amount of energy
                                          3. Further neutrons are also released
                                          4. New neutrons strike other nuclei,
                                          initiating chain reaction

                                           Some believe that the risks involved
                                           outweigh potential benefits. If a reaction
                                           was to go out of control, we would have
                                           another Chernobyl.
Has this assembly got anything to do with me?

Of course it has!!!

Firstly you have a nuclear power station down the road.

Secondly, your generation is going to have to decide the energy source of the
future – you need to be sure that you make the right choice!

Thirdly, we live in a democratic state and you’re the electorate of tomorrow.
