The Chernobyl disaster was the worst nuclear accident in history, occurring on April 26, 1986 at the Chernobyl Nuclear Power Plant in Ukraine. An unexpected power surge during a reactor systems test caused a series of explosions, resulting in a fire that released large amounts of radioactive material into the atmosphere. The radioactive fallout contaminated Ukraine, Belarus, Russia, and other surrounding areas, exposing hundreds of thousands of recovery workers and evacuees to radiation and resulting in both immediate and long-term health issues. The environmental effects of the contamination persist in the region.

• LOCATED IN UKRAINE
• 20KM SOUTH OF BELARUS

3. Disaster overview
•
ACCIDENT OCCURED ON SATURDAY, 26 APRIL 1986
•
STARTED AT REACTOR NUMBER 4
•
UNEXPECTED POWER SURGE LEAD TO VESSEL RUPTURE AND EXPLOSIONS
•
GRAPHITE MODERATOR BEGAN REACTING, IGNITED
•
RESULTING FIRE THROW OUT HIGHLY RADIOACTIVE FALLOUT IN ATMOSPHERE

4. Reactor 4 – Chernobyl plant

5. Radiation from Chernobyl
UKRAINE, BELARUS,
RUSSIA, SWEDEN AND
MANY OTHERS WERE
CONTAMINATED BY
RADIOACTIVE
FALLOUT

6. Extent of Chernobyl accident
•
LEAD TO THE RELEASE OF HUGE AMOUNT OF RADIOACTIVE MATERIALS
•
400 TIMES STRONGER THAN HIROSHIMA ATOMIC BOMB EXPLOSION
•
600,000 PEOPLE INVOLVED IN EMERGENCY CONTAINMENT, CLEANING AND
RECOVERY OPERATIONS
•
LAKHS OF PEOPLE EVACUATED FROM REACTOR SITE
•
AT PRESENT, MORE THAN 5 MILLION PEOPLE SAID TO BE CONTAMINATED

7. Chernobyl before and after

8. Effects on human
•
PEOPLE EXPOSED TO RADIATION DIRECTLY (RADIOACTIVE CLOUD) AND
INDIRECTLY (FOOD)
•
THYROIDS OF CHILDREN HEAVILY EXPOSED TO RADIOACTIVE IODINE
THROUGH MILK
•
THOUSANDS OF PEOPLE HAD THYROID CANCER DUE TO EXPOSURE
•
CERTAIN TYPES OF LEUKAEMIA AND SOLID CANCER REPORTED
•
CARDIOVASCULAR DISEASES AND CATARACTS WERE ALSO STATED
•
HAD DEFORMITIES IN NEW-BORN BABIES AND MUTATION IN ANIMALS

9. Media of exposure to
radiation – direct
(external) and indirect
(internal)

10. Chernobyl disaster victims

11. EFFECT ON ENVIRONMENT
• URBAN AREAS ARE HEAVILY CONTAMINATED
• AGRICULTURAL FIELDS ARE HEAVILY CONTAMINATED BY RADIOACTIVE WASTE
• INCREASE IN MORTALITY WITH DECREASE IN REPRODUCTION AND
GENETIC ANOMALIES ARE STILL SEEN IN PLANTS AND ANIMALS.

12. Socio Economic Cost of the Disaster
• UKRAINE IS YET TO BECOME AGRICULTURALLY
• SELF-SUFFICIENT
• NEW SETTLEMENT FOR 3,30,000 PEOPLE
• POOR DIETS, UNHEALTHY LIFESTYLES, POVERTY, AND LIMITED ACCESS TO
PRIMARY HEALTH CARE

13. Current Concerns
• MISCONCEPTS AND MYTHS REGARDING RADIATION AND DISASTER ARE
STILL SPREADING AMONG THE SURVIVORS.
• GOVERNMENT IS NOT KEEN IN GIVING PROPER DETAILS.
• LOW INCOME AND VERY HIGH UNEMPLOYMENT

14. Needs of the People
• IMMEDIATE ACTION PLAN TO COPE UP WITH POVERTY, UNEMPLOYMENT AND
ISOLATION.
• GOVERNMENT POLICY IS NEEDED TO NORMALISE THE LIFE OF ENTIRE
AFFECTED POPULATION.
• ACCESS TO INFORMATION ON THE EFFECTS OF THE ACCIDENT, GOOD
QUALITY HEALTH CARE, SOCIAL SERVICES, AND EMPLOYMENT IS NEEDED BY
THE SEVERAL MILLION PEOPLE WHOSE LIVES HAVE BEEN INFLUENCED
ONLY MILDLY BY THE ACCIDENT.
