What is a gamma ray used for in every day life?

Answer 1

Applications of gamma rays include sterilizing medical equipment (as an alternative to autoclaves or chemical means), removing decay-causing bacteria from many foods or preventing fruit and vegetables from sprouting to maintain freshness and flavor.

Answer 2

Here are a small number of "everyday life" uses of gamma rays:

• certain types of cancer radiation therapy
• scanning large shipping containers for contraband or explosives when they arrive at ports
• industrial inspection of metal castings for fractures (your car's engine block might have been inspected this way)

There are many other uses more removed from "everyday life".

Answer 3

They're often used to 'sterilise' items people take into another country - to kill bacteria etc that may be harmful to the destination country's wildlife.
