Question

What are three benefits of radioactivity?

Answer 1

Element formation, mutation and dating.

Explanation:

I could add power generation as well, but that's over in another subject. Biologically radioactivity is an important phenomenon because it is responsible for the existence of many of the varieties of elements.

In life systems radioactivity can result in genetic changes - for good or ill - that alter the structure and mechanisms of living organisms.

Finally, in this topic, it is very useful for dating organic materials from ancient history by the known decay mechanisms and times of the original elements.
