6.2 Nuclear Radiation
Beta
Emitted when a neutron turns into a proton in nucleus
High speed electron
Thickness detectors
Beta particles passed through paper
Machine stopped if paper is too thick
Nuclear rearrangement
After nuclear decay, gamma radiation may be given off
Highly ionising
Alpha
2 neutrons and 2 protons (same as helium nucleus)
Smoke alarms
Alpha particles sit between two charged plates
No current flows if there's smoke
Ionising radiation
Damages body cells
Causes mutations that lead to cancer
CT scans
X-ray scans combined to produce 3D image of body
Radiotherapy
Radiation focused to kill cancerous cells
Gamma
EM radiation
Irradiation
Object is exposed to radiation without becoming radioactive
