The quantity of ionizing radiation exposure is measured in which unit?

Explanation:
Exposure measures how much ionization is produced in air by ionizing radiation. The standard unit for that exposure is the Roentgen, which historically defines the amount of charge produced per kilogram of air. Rems and Sieverts gauge dose equivalent, reflecting biological effect, not the amount of exposure in air. Curies measure activity, the rate of radioactive decay, not exposure. So Roentgens are the correct unit for exposure.
