The incident in London during November 2006 involving a lethal intake by Mr. Alexander Litvinenko of the highly-radioactive, alpha-particles-emitting polonium-210 (Po-210) isotope, presumably via ingestion, sparked renewed interest in the area of Po-210 toxicity to humans. This paper is the result of assembling and interpreting existing Po-210 data within the context of what is considered a rel...

This paper presents the results of a 4 year study to investigate the human alimentary tract transfer factor (f(A) value) and body retention of 210 Po in shellfish. In the first 3 years, mussels (Mytilus edulis L.), cockles (Cerastoderma edule L.) and brown meat from crab (Cancer pagurus L.) were successively studied. In each year five volunteers (from a pool of seven) ate a suitable portion of ...

Chemistry International, 1998, Vol. 20, No. 5 sor of Physics at Vienna, Lvov and Cracow universities developed the theory of fluctuations in gases and, independently of Einstein, proposed the theory of Brownian motion. Subsequent experimental confirmation of the Einstein–Smoluchowski equation became one of the final proofs in the kinetic theory of matter. Great achievements in organic chemistry...
