Why is gamma radiation used for strawberries?

Answer 1

it was to kill the spores in the strawberry. However, it was not dangerous to human because it is not radioactive. Gamma rays are only high energy bolts.

Imagine that radiation is similar to sunlight, where the sun is the emitter of radiation (constantly emitting rays/particles of radiation), and sunlight is the rays of energy emitted by the sun.

Now imagine what happens when light passes through glass, it doesn't affect the glass. But it can create reflections. Gamma rays are similar, they can pass right through a strawberry; however, any living beings on this strawberry (like mold and bacteria) will be killed because radiation dose is harmful to living things. Now, the sunlight that passes through glass does not remain in the glass, it passes through. In this same way, the gamma radiation that went through this strawberry has already passed through and is long gone, it's damage, or in this case good, has already taken place and because there is no residual radiation left in the food it is safe for eating. To understand in more depth would require intimate knowledge of chemistry and physics.

Just realize that the strawberry sellers are not out to harm you. They want you to live long lives and to eat lots of strawberries.
