Root Explanation

Irradiator → It is formed from "ir-" (meaning not) and "radiator" (from Latin "radiatus", meaning to emit rays). The word "irradiator" refers to a device that does not emit rays, often used in contexts where radiation is involved.

Memory Tip

Think of something that does not emit rays ('ir-' means not, and 'radiator' means to emit rays) — that's why an irradiator is a device that does not produce radiation.
