Industry
Carbon dating
Detecting Radiation
Dosimeter/ Film badge
Geiger Muller (GM) tube
Photographic film
The darker the film the more the radiation
Dangers
Mutations
Small amount of ionizing radiation but over a long period of time can damage our DNA
Not all are harmful
Kill cells
cells that cause cancers
Alpha's the most dangerous inside
most ionizing
Gamma's the most dangerous outside
Most penetration
Tumor
Pre-cancerous
Cancerous (Malignant)
Non-cancerous (Benign)
Radiation exposure
Irradiation
Outside the body
Less likely to be absorbed. Less ionizing
Alpha won't reach the body
Contamination
Inside the body; on our skin
Easily be absorbed
Cause Ionisation and cellular mutations
Will reach our body/ Harder to stop or prevent
