Nucleur Fission

Question 1

What is nucleur fission?

Answer 1

Large, unstable nuclei are split into smaller, stable nuclei by firing neutrons at them. As they split, the nuclei release large amount of energy in the form of gamma radiation.

Question 2

List the 4 stages of nucleur fission:

Answer 2

1. A neutron is absorbed by the U-235 nucleus
2. This forms larger nucleus (U-236) which decays
3. It splits into 2 daughter nuclei
4. Releases neutrons, gamma radiation, energy
