She obtained polonium from pitchblende, a material that contains uranium, after noticing that ** <span style="background-color: #000000; color: #f6eb93; font-family: Georgia,serif; font-size: 116.48%;"> unrefined pitchblende was more radioactive than the uranium that was separated from it. Polonium is a radioactive, extremely rare semi-metal. It is reactive, silvery-gray, it dissolves in dilute acids, but it is only slightly soluble in alkalis. it is fairly volatile: about half of a sample of it will evaporate within 3 days (unless it is kept in a sealed container). // ==

The proof is that it can be found in the blood and urine of smokers. The circulating polonium -210 causes genetic damage and early death from diseases reminiscent of early radiological pioneers: liver and bladder cancer, stomach ulcer, leukemia, cirrhosis of liver, and cardiovascular disease. //==

==//<span style="background-color: #000000; color: #f6eb93; font-family: Georgia,serif; font-size: 116.48%;">The environmental and biochemical forces which may tend to reconcentrate these toxic materials in living cells are not well known. Although polonium occurs naturally, it has become much more available for entering into water, food, living cells and tissue since the mining boom which began shortly after the Second World War. //==
