Polonium-210 must be ingested or inhaled to cause damage - breathing it in, taking it into the mouth or getting it into a wound. And because the radiation has a very short range, it harms only So all the radioactive decay products of uranium remain in the crushed rock when uranium is separated from the ore. That's why Marie Curie found most of the radioactivity left behind in the residues, including all the radium and all the polonium. Radium. Well, how did the story of uranium progress?

London - Polonium, which Swiss scientists conclude was likely to have been used to poison Discovered by Marie Curie in 1898, Polonium-210 is one of 20 known radioactive isotopes of the element, according to Chemistry World. Toxicologists say a single gram of the substance could kill as Heavy smokers may be exposed to the same amount of radiation (estimates vary from 100 µSv to 160 mSv per year) as individuals in Poland were from Chernobyl fallout traveling from Ukraine. As a result, 210 Po is most dangerous when inhaled from cigarette smoke, providing further evidence for a link between smoking and lung cancer.

It appears that cigarette contains polonium, an extremely toxic compound. Polonium is a highly radioactive chemical with no stable isotopes. It was discovered in 1898 by Marie Curie herself – together with Pierre Curie.
