Eli5: How does radioactivity kill/mutate the body?

502 views

Apologies if the tag is wrong!

From what I understand, the radiation doesn’t do squat untill it’s ionized. The way it was explained to me is that the Radiation is the knife, while the ionization is the hand weilding the knife.

So how does it affect the body? I know it does something to our DNA but what does it do specifically?

Bonus Question: What did scifi writers assume Gamma Ray’s would do to Bruce Banner to make him the Hulk, as opposed to what it does IRL and just… kill you.

It’s not the radiation that’s ionized; it’s the target.

An ion is an atom which has an electrical charge, i.e. it has more or fewer electrons than protons. Chemistry is the science of atoms getting together so that they have the same, so ionization upsets the natural order of things.

Dunno about the Hulk … maybe the idea is that he’s filled with energy?
