Polonium produce intense alpha particles that generate considerable heat, which is used as source of atomic heat to run radioisotope thermoelectric generators in moon rovers and various satellites. Polonium-210 is a very strong emitter of alpha particles. Polonium was discovered by Marie Curie and her husband Pierre Curie in 1898. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). A low resistivity indicates a material that readily allows the flow of electric current. A few curies (1 curie equals 37 gigabecquerels, 1 Ci = 37 GBq) of 210Po emit a blue glow which is caused by ionisationof the surrounding air. These numbers may well differ considerably from, say, single bond energies in a solid. Element 84 of Periodic table is Polonium with atomic number 84, atomic weight 209. Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. To understand the difference between metals, semiconductors and electrical insulators, we have to define the following terms from solid-state physics: A possible crystal structure of Polonium is rhombohedral structure. A milligram emits as many alpha particles as 5 g of radium. Named after Poland, this element has a notorious reputation because of its use in atomic bombs and international murder allegations.
