Alpha radiation delivers a large amount of energy to living cells and can cause considerable damage and cell death. Alpha particles lose most of their energy on impact, and cannot move further into matter, hence alpha radiation does not penetrate through surfaces (e.g. paper, human skin or clothes). Science Chemistry Half-life The half life of polonium-210 is 140 days. If you begin with a 1200 gram sample, how much Solution for Polonium-210 has a half-life of 140 days.

Polonium-210 is an isotope of polonium. It undergoes alpha decay to stablePb with a half-life of 138.376 days, the longest of all naturally occurring polonium Making a Poisoner: Half-life in a scientific detective story. Former Palestinian Liberation Organization leader Yasser Arafat died in November 2004 in a French Po-210 emits alpha particles and is 5,000 times more radioactive than radium. The half-life of Po-210 is 138 days.
Polonium-2 10 is an alpha emitter that has a half-life of 138.39 days. A milligram of polonium-210 emits as many alpha particles as 5 grams of radium. A great
The radioactivity decays away in about two-and-a-half years. In its most common form , most This forms bismuth-210 which has a half-life of 5 days. Bismuth-210 decays to polonium-210 through a beta decay.

Radioactive polonium poses a health hazard only if the radionuclide is taken in by the body through food or drinking water, through breathing (inhalation) or if it enters the body through open wounds in the skin for example. Suppose a laboratory has a 30 g sample of polonium-210.
