The roentgen (R, also röntgen) is a unit of measurement for exposure to ionizing radiation (such as X-ray and gamma rays), and is named after the German physicist Wilhelm Röntgen. Adopted in 1928[1], 1 R is the amount of radiation required to liberate positive and negative charges of one electrostatic unit of charge (esu or StatCoulomb) in one cubic centimeter of dry air at standard temperature and pressure (STP).
