A large x-ray image that shows very small details, often used in scientific studies.
The scientist examined the microradiograph to analyze the tiny structures in the sample.
Microradiograph → It is formed from "micro-" (from Greek "mikros", meaning small) and "radiograph" (from Latin "radius", meaning ray, and "graph" from Greek "grapho", meaning to write or record). The word refers to a small image or record made using rays, typically X-rays, to visualize objects that are too small to be seen with the naked eye.
Think of 'small' ('micro-') and 'recording with rays' ('radiograph') to remember that a microradiograph is a small image created using rays.
