Radiation-Exposure Converter

Radiation-exposure is a quantity that measures to what extent ionizing radiation produces electric charges in a given volume of air. It tells you to what extent a field of ionizing radiation (X-rays or gamma rays) causes ionization in air.

It does not measure energy absorbed by a person or material, but measures the ionization caused per unit mass by the radiation.

Ionizing radiation creates charged ions by removing electrons from air molecules as it travels through the atmosphere.

The total electric charge of one sign (positive or negative) released per unit quantity of air is measured via radiation exposure. This aids in characterizing the strength of an X-ray or gamma-ray field at a given location.
