Radioprotective → It is formed from "radio-" (from Latin *radius*, meaning ray) and "protective" (from Latin *protectivus*, meaning serving to protect). The word "radioprotective" refers to something that serves to protect against rays, particularly ionizing radiation.
Think of 'rays' ('radio-') that need 'protection' — that's why radioprotective means something that protects against harmful rays.
