Physics Test Content - Part 2 (WEEK 7)

Radioactive Decay:

Stochastic process (occurs randomly) where an unstable nucleus decays spontaneously, emitting particles of ionising radiation.

• After decay, parent atom becomes daughter atom.

Radioactive Decay Chain:

Daughter nucleus more stable than parent.

*If not the case, it will continue to undergo radioactive decay to become stable.

Radioactive Decay Modes:

Decay Can Cause Emission Of 3 Ionising Particles…

1. Alpha (α)

2. Beta (β)

3. Gamma (γ)
