What is background radiation?
Radiation that we are naturally exposed to
How does radiation occur from Radon gas?
It comes from the decay of Uranium in rocks and can be inhaled
What is the Geiger-Müller Tube? How does it work?
Detects radiation.
It works by detecting when gas inside a chamber is ionised by radiation.
Every click or beep is one incident of radiation

Photographic film
Becquerel
What affects radioactivity of an object?

What is activity?
The number of decays per second
Can we predict when an atom decays?
No, it’s random
What is half life?
The time it takes for the activity of a sample to halve
