Illustration of element, icon, transition - 209060030 Nov 28, 2018 - 45: “The Deadly Metal, Polonium”: Discovered by Marie Curie (1867-1934) in 1898, polonium (atomic number 84) was only classed as seriously hazardous in 1949-1950. The median lethal dose is less than 1 microgram. The story quotes a health officer who had to wash his hands with borax 18 times to get rid of traces.

Polonium is a chemical element with the symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lea Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).
