 He was elected in 1946 a Corresponding Member of the U.S.S.R. 

 Academy of Sciences. In 1948 he received a Stalin Prize. 



Nenadkevich studied new types of mineral raw materials 

 and developed methods for obtaining rare metals from ores.

 metallic bismuth from domestic raw materials and conducted 

 its first experimental smelting. In 1926 he chemically ascer- 

 tained the age of one of the most ancient minerals— uraninite.
