Radioactivity
Medical
Cancer
Kills the cancer cells, or slows their growth by damaging their DNA, this will kill the cancer cells. It can take weeks of treatment to kill the cells
Steroliseing
As gamma rays pass through medical equipment it will kill all living tissue and cells. This leaves the equipment clean and sterolised for medical use
Radioactive tracers can be used to investigate a paitents body, the source is either beta or alpha, it will be injected and then using a radiographer will create an image of the internal organs of the paitiant

Thickness monitoring
Radioactive tracers can be used to mesure the thickness of paper, plastic sheets and foil, this is by fireing the radioactive tracers through it and reciving an amount on the other side, this is enough information to be able to guage the thickness of a product
Tracers
Can determine the distribution of an object in a natural system, the more tracers, the more substance
Weld checking
if a tracer is put on one side and a film on the other side, spots of darkness indicate air bubbles and impurities in the weld.
Consumer products
Fire alarms have a small amount of americum 244 which will ionise the air creating a current, when the current end it means that smoke has gotten into the alarm.
Gamma rays can be used to sterolise food and kill bacteria, insects and mould, this can change the taste but makes it safer and increases the shelf life of food
Miscelaneous
Carbon Dateing is used by mesuing the amount of carbon 14 left in a product, guaging off of its half life it will tell you the last time the animal respirated.
