röntgent

Röntgent is a unit of measurement used to quantify the amount of ionizing radiation, specifically X-rays and gamma rays, absorbed by matter. The name "röntgent" is derived from the German physicist Wilhelm Conrad Röntgen, who discovered X-rays in 1895. The röntgent is defined as the amount of radiation required to produce ions carrying one electrostatic unit of charge in one cubic centimeter of dry air at standard temperature and pressure. It is a relatively large unit of measurement, and in modern practice, the gray (Gy) is more commonly used, as it is defined in terms of the joule per kilogram (J/kg), making it more directly related to the energy absorbed by matter. The röntgent is still used in some contexts, particularly in the field of radiation protection, where it can be useful for comparing the biological effects of different types of radiation.
