11. How to Prevent Similar Accidents


The Chernobyl disaster involved negligence and a disregard for routine safety instructions.
If we want to avoid similar accidents, we need to learn to follow and respect procedures that are there for our safety.
Are nuclear electric plants safe?
By present-day standards the number of people killed in nuclear electric plants is very small. Statistic of deaths per 1 TWh (Tetra Watt hour)

Petroleum electric power plant – 4.4 died / TWh
Black coal electric power plant – 2.4 died / TWh
Brown coal electric power plant – 2.1 died / TWh
Gas electric power plant – 1.9 died / TWh
Nuclear electric power plant – 1.2 / TWh


IAEA (International atomic Energy Agency) are nuclear power electric plants safeties than coals, petroleum and gas power electric plants. People also have choices of various safe types of electricity:
Green energy, Geothermal energy, Sun energy, Water energy, Wind energy.
Why is the most popular from of energy nuclear electric plants? Because electricity from nuclear power electric plant is cheaper and faster than other methods.
What is a greater priority many or health?

12. Could a “Chernobyl” Happen in Hawaii?

Why should people in Hawaii know about what happened in Chernobyl?
The Chernobyl disaster addresses people in everywhere because the contamination not only effected Europe, but the entire world. It contaminated the water, ground and air. The most dangerous from of contamination is in water, which goes into our rivers, seas, and oceans throughout the world. We are all connected by water.
A similar disaster could be repeated anywhere in the world. People should know about this problem and learn from others mistakes.
I’ve accomplished 47.5% on my quizzes. I hope this percent will increase, and that my project will help educate people who are interested in this subject.
