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.

Gordon Wallace (professor) been focused on exploring the development and use of such materials in biomolecular technologies – he has led a number of initiatives in developing the field of organic bionics. He has developed collaborative research relationships with the inventor of the Cochlear Bionic Ear, Professor Graeme Clark as well as Professor Stephen O'Leary, Professor Peter Choong, and Professor Mark Cook which have led to significant developments in the field of new materials for medical bionics. He has now established a significant national clinic network with others including Professor Chris Baker, Professor Michael Coote, Professor Toby Coates, Professor Gerard Sutton, Professor Stuart
