Polonium is used to eliminate static electricity produced during processes such as rolling paper, wire and sheet metal. Polonium can be mixed or alloyed with beryllium to provide a source of neutrons. It is also used in anti-static brushes to eliminate dust on photographic film. What does the 218 in polonium-218 represent. A certain isotope has 72 protons, 72 electrons and 106 neutrons. How many neutrons does polonium 210 have. 126.

The chemical symbol for Polonium is Po. Neutron Number and Mass Number of Polonium Mass numbers of typical isotopes of Polonium are 208-210. 2009-10-27 Name: Polonium Symbol: Po Atomic Number: 84 Atomic Mass: (209.0) amu Melting Point: 254.0 °C (527.15 K, 489.2 °F) Boiling Point: 962.0 °C (1235.15 K, 1763.6 °F) Number of Protons/Electrons: 84 Number of Neutrons: 125 Classification: Metalloid Crystal Structure: Monoclinic Density @ 293 K: 9.4 g/cm 3 Color: Unknown Atomic Structure 2010-05-17 Polonium-210 is an isotope that emits alpha particles single energy and not followed by any additional radiation. This alleviates the analysis of signals by the electronic circuitry. In order to get a depth distribution that will emphasize the functionality of the system, we decided to do a polonium-210 surface implantation on a thin silver foil.
