Tracers- a radioactive source is put into a system (like a piping network), it will build up where there is a blockage a be detected, showing where a problem is.
Medical tracers- a radioactive source is put into a body and will build up at a blockage so an area of problem can be detected.
Radiotherapy- radiation is used to destroy unwanted cells (cancerous cells.)
Radioactive dating- aka carbon dating. The amount of radiation from an object is measured, the half life of the carbon is then used to see how old the object is. Archaeologists use this to tell the age of an object.
