The half life of polonium-210, 210Po is 138 days. A sample amount has a mass of 110 mg. The element decays according to the following equation: (In 2)t A(t) = 110e-138- Find the mass of the sample after 552 days. Title: Polonium-210 Information Sheet Author: The Health Physics Society Created Date: 11/30/2006 9:22:06 AM One Half-Life of polonium = 138 days We have to find the number of half-lives that occur in 1104 days. For this we simply divide 1104 by 138. Number of half-lives in 1104 days = 1104/138 = 8 half-lives Thus, in 1104 days polonium-210 undergoes 8 half-lives i.e. it is halved 8 times.
Shielding gives an exponential decay for the same reason that half-lives behavior gives exponential We use polonium-210, which has a very short half- life. USNRC License Exempt (US only). Outside the US, consult local laws and regulations. Below is the isotope, activity, half-life and type of radiation: Po-210, 0.1 neutrons (such as a helium nucleus), the 210Po molecule decays into stable Lead 206 (206Pb) with a half-life of approximately 138 days. Alpha particles are the Half-life: 1600 years.

210Po has a half-life 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.
National Emission Standards for Hazardous Air Pollutants
Alpha radiation delivers a large amount of energy to living cells and can cause considerable damage and cell death. Half life is the time it takes a substance to decrease by half. This is sometimes known as exponential decay. You can determine how much is left of something Polonium-210 has a physical half-life of 138 days. It emits alpha particles during its radioactive decay to lead-206. 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.
