Nuclear Energy

a. Where does radiation come from? What does radioactive decay have to do with its creation? A) radiation comes from the emitted energy (gamma) emitted proton (beta) and emitted electron (alpha) this occurs when the element is in an excited state radioactive decay is the loss of electrons or protons

b. Explain which type of radiation (Alpha, Beta or Gamma) is considered to be the most dangerous to humans. gamma destroys cells and can go through wood but not through lead its the most dangerous

5/2 = 2.5 2.5=5700 years

5700 + 5700 = 11400

d. Describe the difference, at the atomic level, between fusion and fission. A) cant remember…

e. Fusion or fission?

Which one is used in our nuclear power plants? fusion
Which one is happening in the Sun? fission
Which one creates more dangerous radioactive waste? fission
Which one creates more energy for the amount of material used? fission
