Eos, Transactions American Geophysical Union, 1980 I welcome York's contribution [York, 1979] to the exchange of views concerning the possible existence and potential cosmological implications of polonium halos in Precambrian granites [Damon, 1979; Gentry, 1979], but I must take exception to some omissions from his comments about my results on Po halos.York seems to regard even the existence of Po ...

Health Risk Evaluations for Ingestion Exposure of Humans to Polonium-210
Dose-Response, 2007 The incident in London during November 2006 involving a lethal intake by Mr. Alexander Litvinenko of the highly-radioactive, alpha-particles-emitting polonium-210 (Po-210) isotope, presumably via ingestion, sparked renewed interest in the area of Po-210 ...

Activity Levels of Polonium-210 in Tobacco and Cigarette in Iran [PDF]
مجله علوم و فنون هستهای, 2011 Polonium-210 (210Po) is a natural contaminant of tobacco and its products. Due to its volatility and inherent adsorption properties, 210Po is one of the major potential sources of human exposure through smoking.

Study of radioactive decay process of uranium atoms via fractals-fractional analysis
South African Journal of Chemical EngineeringThis manuscript is devoted to derive a mathematical formulation for radioactivity process of uranium to radium which decays to produce radon. Radon which further decays to produce polonium atoms.

, 2009 The thermodynamical properties of the main phases of metallic polonium are examined using Density Functional Theory. The exceptional nature of the solid-solid phase transition of $α$ to $β$ Po is underlined: it induces a lowering in symmetry, from cubic to rhombohedral, with increasing temperature.
