The radiation a person receives from the sun is characterized as

natural background radiation

After an x-ray photon interacts with an atom and ejects its electron from it orbit, the atom now becomes

A positively charged ion.

Erythema, reddening of the skin after exposure to high doses of radiation is categorized as a

somatic effect
