11.  Reasons for the accident
 Workers lack of knowledge of reactor physics and engineering, as
well as lack of experience and training
• Delay
• The night shift was not prepared to carry out the experiment
• But it was still carried out
• The operators seem to have been unaware of the xenon
poisoning
 Insufficient communication between the safety officers and the
operators in charge of the experiment
 Disabled all safety system .

12.  IMMEDIATE IMPACT

 203 people were
hospitalized immediately.
 31 of them eventually
died. Most of these people
were workers in the plant or
local firefighters.

13.  NW winds from the Black Sea carried the radiation for miles in
the following days.

14.  The explosion released 190 tons of radioactive gases
into the atmosphere in only 32 hours.

15.  In all 150,000 square kilometres in Belarus, Russia and
Ukraine were contaminated .

21.  THE LAND OF BELARUS
 10% of the land is unusable
 25% of the country's farmland and forest contaminated at a
dangerous level

22.  FOOD & WATER
 Milk—Farmers have to watch the radiation level in
milk.
 Fish—Cannot be eaten, as water absorbs radiation and
fats concentrate it .
