Thanks to books, movies and television shows, this is what most of us think of when we think about nuclear energy!
In reality, there are many other things we should think about first.
Electricity
Medicine
Space Exploration
During the course of this chapter we are going to learn:
- The discovery of Radioactivity- Radioactive decay
- The penetrating power of Radiation - Determining age using radioactive decay
- Nuclear fission and nuclear fusion- Nuclear industry- Accidents
Two atoms are sitting in class
The first atom says to the second:“I think I lost an electron!”
The second atom replies: “Are you sure?”
The first atom responds:I’m positive!
Marie Curie and her husband Pierre conducted early research that lead to the discovery of the Theory of Radiation. Marie’s research would eventually lead to her being awarded two Nobel prizes.
Her research would also lead to her death from exposure to radiation!
Beta Decay of Hydrogen 3 to Helium 3
Electron Capture of Beryllium-7 decaying to Lithium-7.
Two types of Beta Decay
Pop Quiz
Who developed the Theory of Radioactivity?Marie Curie
Name the three types of radioactive decayAlphaBeta
Gamma
What particle is emitted during Alpha Decay?A helium nucleus called an Alpha Particle

Radioactive Decay and Half-LifeAtoms decay at a constant rate
The time it take for half of the atoms in a give sample to decay is the atoms Half-Life
Check out the half-life of various isotopes at the below site
Scientists will determine the age of this baby mammoth, found frozen in Siberia, using the half-life of Carbon-14 which is 5,730 years
Penetrating Power of Radiation
Medical X-rays and CAT scans are created thanks to the penetrating power of radiation.
Nuclear FissionWhy did the student bring a rod and reel to class
The teacher said they would be studying fission!
