Description: 
Primary research interests of the Institute are ore and mineral 
analysis. A specific interest involves the quantitative determination of 
trace elements and rare earths in complex ores. Emphasis is placed on the 
development of new methods and instrumentation to be used in mineralogical 
analysis. The Radiochemical Laboratory of this institute recently developed 
an instrument called an atomic spectrometer in which radiation from a 
radioactive source located centrally in a fine mineral powder causes the 
chemical elements of the powder to emit characteristic X-rays. A compact, 
electronic computing apparatus acts as a recording and analyzing device to 
give the qualitative and quantitative analysis of the mineral powder. 
It publishes a Trudy.
