Roentgen (unit) capped at 3 MeV in 1950. The USSR all-union committee of standards (GOST) had meanwhile adopted a significantly different definition of the roentgen in 1934. GOST standard 7623 defined it as "the physical dose of X-rays which produces charges each of one electrostatic unit in magnitude per cm of irradiated volume in air at 0 °C and normal atmospheric pressure when ionization is complete." The distinction of physical dose from dose caused confusion, some of which may have led Cantrill and Parker report that the roentgen had become shorthand for 83 ergs per gram (0.0083 Gy) of tissue.

Kaiser Wilhelm II Land 370 metre high extinct volcano which was named after the mathematician and physicist Carl Friedrich Gauss. Kaiser Wilhelm II Land Kaiser Wilhelm II Land (also Wilhelm II Coast) is the part of Antarctica lying between Cape Penck, at 87°43'E, and Cape Filchner, at 91°54'E and is claimed as part of the Australian Antarctic Territory, although this claim is not universally recognized. The area was discovered on February 22, 1902 during the Gauss expedition (1901-1903), led by Arctic veteran and geology professor Erich von Drygalski. Drygalski named it after Kaiser Wilhelm II who had funded the expedition with 1.2 million Goldmarks.
