Amares Chatt, FCIC, has been awarded the George Hevesy Medal Award 2001 "for his outstanding and innovative contributions in the field of radioanalytical and nuclear chemistry, in particular for his work on various forms of instrumental, preconcentration and radiochemical activation analysis, and their applications in a wide variety of different medical, environmental and biological research studies." The Hevesy Medal is an international award of excellence in radioanalytical and nuclear chemistry.
It occurred to the Hungarian-born chemist Georg Karl von Hevesy (1885-1966) that it might be possible to use radioactive atoms as tracers.
Just as he was about to start his lecture on receipt of the 1922 Nobel Prize for physics, Bohr learned that back in Copenhagen this theory had passed a serious test as the Hungarian physicist George Hevesy discovered element 72 according to its prescriptions.
