Nanoparticles in Humans

Lev S. Ruzer (1922–2014) was a researcher in the Indoor Environment Department, Environment Energy Technologies Division, at the Lawrence Berkeley National Laboratory, USA. He received his education in the former USSR and began his scientific career with research on dose assessment in animals exposed to radon and its decay products. On the basis of this theoretical and experimental work, he obtained his degree as a candidate of physicomathematical sciences (equivalent to a PhD) in 1961 from the Moscow Engineering Physics Institute. From 1961 to 1979, he was the founder and chair of the Aerosol Laboratory at the Institute of Physical-Technical and Radiotechnical Measurements, Moscow. The set of installations developed under his supervision for generating and measuring different types of aerosols was certified as the State Standard of Aerosols in the former USSR. This work did not have an equivalent at the time. His book on radioactive aerosols came out in 1968. Dr. Ruzer arrived in the United States in 1987 and joined the Lawrence Berkeley National Laboratory in 1989. He published more than 130 papers, edited 2 books, authored 3 books, and had 3 patents to his credit. He was on the editorial boards of several international journals.
