A technique used to create images of the distribution of radioactive materials in a sample, often used in scientific research and medical diagnostics.
The scientist used autoradiography to visualize the distribution of the drug in the tissue samples.
Autoradiography is formed from "auto-" (meaning self) and "radiograph" (from "radius" meaning ray and "grapho" meaning to write). The term describes a method of imaging that uses the radiation emitted by a sample itself to create an image, hence the concept of self-writing with rays.
Think of 'auto-' meaning self, and 'radiograph' referring to writing with rays. This helps you remember that autoradiography is a technique that creates images using the sample's own emitted rays.
