The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them.
10 out of 10 people die... Do you still feel special?
from my understanding...
ionizing radiation is the most dangerous to cells... gamma/xray waves
non-ionizing radiation is still bad, but does not mutate cells into cancer at the level ionizing does ... micro/radio waves
Who better to ask?

Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized.
Here we are concerned with only one type of radiation, ionizing radiation, which occurs in two forms: waves or
particles.
Ionizing radiation is any type of particle or electromagnetic wave that carries enough energy to ionize or remove electrons from an atom.
Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation.
