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. Mode of decay: alpha Mode of decay: alpha into Po-218 Lead-210. (Historically Pb-210 is also called radium D). Half-life: 22.3 years. This table shows that the intake of Lead-210 and Polonium-210 through ingestion accounts for a significant 5 days) → Polonium-210 (half-life of approx .
(a) Find a function that models the amount of the sample remaining at time t. (b) Find the mass remaining after one year. (c) How long will it take for the sample to decay to a mass of 200 mg? (d) Draw a graph of the sample mass as a function of time.

Biological half-life Radioactive potassium, 4 K, with a physical half-life of 1.28 billion years, is found in Bly-210 och polonium-210 är andra.
210 Po (half-life 138.376 days) is the most widely available and is made via neutron capture by natural bismuth. The longer-lived 209 Po (half-life 125.2 ± 3.3 years, longest-lived of all polonium isotopes) [2] and 208 Po (half-life 2.9 years) can be made through the alpha, proton, or deuteron bombardment of lead or bismuth in a cyclotron . half-life of Po-210 is about 140 days.
