A scientist who examines how radiation affects living things.
The radiobiologist conducted experiments to understand the impact of radiation on cells.
Radiobiologist → It is formed from "radio-" (from Latin *radius*, meaning ray) and "biologist" (from Greek *bios*, meaning life, and *logia*, meaning study). The word refers to a scientist who studies the effects of radiation on living organisms.
Think of 'rays' ('radio-') affecting 'life' ('bios') — that's why a radiobiologist studies how radiation impacts living things.
