Prepared by Cesar Harada for the Hong Kong Harbour School, Sept 6th 2014 Better google presentation with videos embedded : http://goo.gl/cKiFAE Introduction to nuclear power, weapons and radioactive pollution in the environment for school kids. No science background required. We are trying to address the questions and anxieties kids may have about the nuclear power. We explain how we can contribute to a better understanding of radioactivity in the environment from a citizen science perspective.

Introduction to nuclear power, weapons and
radioactive pollution in the environment for school
kids. No science background required. We are trying
to address the questions and anxieties kids may
have about the nuclear power. We explain how we
can contribute to a better understanding of
radioactivity in the environment from a citizen
science perspective.

2. What is matter? What is a nucleus?
All the objects from everyday life that we can bump
into, touch or squeeze are composed of atoms. This
atomic matter is in turn made up of interacting
subatomic particles—usually a nucleus of protons and
neutrons, and a cloud of orbiting electrons.
http://en.wikipedia.org/wiki/Matter
“The Powers of Ten” (1977)films are two short American documentary films
written and directed by Charles and Ray Eames.

3. Element, Mass, Speed, Stability

4. What is nuclear energy? Nuclear Fission and fusion, Nuclear Power plant and the Large Hadron Collider
Fusion and Fission Nuclear power plant Large Hadron Collider

5. Radioactivity and human health. Chernobyl & Pripyat

6. What is a “safe” level of exposition to radioactivity?

7. What is a nuclear bomb? What happened in Hiroshima & Nagasaki?
1944 “Little Boy” on
Hiroshima was 12Kt
1961 “Tsar Bomba” 57’000 Kt
4750 times more power

8. Where are nuclear bombs today?

This documentary was made in 1984, at the
peak of the cold war era, when the
possibility of a nuclear World War III was a
palpable possibility.

10. The current crisis in Fukushima Japan

11. What happened in Chernobyl & Pripyat

12. Where is nuclear waste ?
Buried in “geological repositories”. In the oceans.

13. Pros and cons of nuclear power
Pros
● Steady, predictable
● Low Co2 emissions
● Stable cost
● Energy independency
Cons
● Accident, war vulnerability
● Radioactive waste disposal
● Global climate potential impact
● Security, economic, social and health concerns

14. Precautionary principle is not applied for nuclear power. Game Theory and deception is use as nuclear weapons proliferate.
“The precept that an action should not be taken if the consequences are uncertain and potentially
dangerous.”
“We do not inherit the Earth from our Ancestors, we borrow it from our Children”
The cold war continues as we keep producing more nuclear weapons on every sides.

When the balance of power is shifting, how
can a declining nation’s desire to preserve the
status quo be reconciled with an ascending
rival’s desire to revise the world order to
reflect its rising power?

citizens.htm
China should gear up for many fights with
"new historical characteristics" as they move
towards their goals. They need to achieve
"common prosperity" little by little for
everyone and revive China's dreams, Xi said.
