Roentgen

About

Initially, A unit of exposure that measures the ionization produced in air by X-rays or gamma rays rather than direct energy absorption by matter.

Historical Background

Throughout history, Named after Wilhelm Roentgen, whose discovery of X-rays revolutionized the field, this unit was pivotal in early radiation studies. Subsequently, this helped establish its widespread use.

Modern Applications

Today, Today, it is mainly used for instrument calibration and historical comparisons in exposure measurement. Moreover, it continues to serve essential measurement needs.

Gray

About

Primarily, A unit that quantifies the energy deposited by ionizing radiation in a given mass, where each joule per kilogram equates to one gray.

Historical Background

Over time, Named after Louis Harold Gray, this unit was introduced to provide a direct measure of absorbed dose based on energy per unit mass. As a result, it became a standard measurement unit.

Modern Applications

Currently, Widely applied in radiation therapy and protective monitoring to precisely assess energy absorption in tissues. Furthermore, its use continues to expand in various fields.
