In radiation monitoring, which unit assesses the amount of ionization produced in air?

The correct choice is based on the unit that specifically measures ionization in air. The Coulomb per kilogram (C/kg) is a unit of measurement that quantifies the amount of electrical charge produced by ionizing radiation when it interacts with air. This is particularly relevant in the context of radiation monitoring, as it provides a direct assessment of how ionizing radiation affects the environment and can be used to calibrate radiation detection devices.

In radiation monitoring, Coulomb per kilogram is crucial because it recognizes the fundamental process of ionization, which is the primary interaction of radiation with matter. When ionizing radiation hits air particles, it produces ions, and measuring the resulting charge helps to determine the radiation dose.

The other units mentioned—Rem, Gray, and Sievert—are measures of dose, but they do not specifically pertain to the assessment of ionization in air. The Gray is a unit of absorbed dose (energy absorbed per unit mass), the Rem is a unit that considers biological effects of radiation, and the Sievert is also a unit used for measuring dose equivalent, which takes into account the potential biological effects of radiation. While all these units are essential in the field of radiation safety, they do not directly measure ionization in air like Coulomb
