Nuclear Decay

Property of Decay 1

Random: Unable to predict which particle will decay when

Property of Decay 2

Spontaneous : Occurs without external influence or cause

Binding energy per nucleon

Average energy requires to remove a nucleon from a nucleus

Binding energy

minimum energy required to separate all individual nucleons of a nucleus

Conditions for fusion

1. High temperature and pressure to overcome repulsion between nuclei

2. High pressure: Probability of nuclide interactions is increased, facilitating fusion reactions.

Alpha decay

1. Low Penetration power

2. High Penetration Power

Beta Decay

1. Medium penetration power

2. medium ionisation power

gamma decay

1. High penetrating power

2. low ionising power
