Roentgen Ray Introduction

Roentgen ray, also known as X-ray, is a kind of short-wavelength electromagnetic radiation with a wavelength between about 0.001 nm and 10 nm. Roentgen rays have high penetrating power and can penetrate some opaque substances, such as ink paper and wood. This kind of invisible radiation can cause many solid materials to generate visible fluorescence, make photographic film sensitive, and effect air ionization.
