• Q14

What is the difference between ionizing and non-ionizing radiation?

Ionizing radiation is a naturally occurring phenomenon and non-ionizing radiation is only created artificially.

Ionizing radiation has high energy that can remove an electron from the atom, but non-ionizing does not.

Non-ionizing radiation is a naturally occurring phenomenon and ionizing radiation is only created artificially.
