A sample contains 30MBq of 201Pb (half-life time:22years) and 15MBq of 210Bi (half-life time : 5 days) at time t=0.

1) calculate the activity of 210Bi at time t=10days

2) if the sample originally pure 201Pb, then how old is it at a time t=0

Polonium-218 is an alpha emitter with a half-life of 3.0 minutes. **)If a sample contains 55 mg of Po−218 (atomic mass = 218.008965 amu), how many alpha emissions would occur in 27.0 minutes? **)If the polonium were ingested by a person, to what dose of radiation (in Ci) would the person be exposed?

Radioactive isotopes often occur together in mixtures. Suppose a 220g sample contains 131Ba, with a half-life of 12 days, and 47Ca, with a half-life of 4.5 days. If there are initially twice as many calcium atoms as there are barium atoms, what will be the ratio of calcium atoms to barium atoms 2.10 weeks later? NCa/NBa = ?

The half-life of a radioactive isotope represents the average time it would take half of a collection of this type of nucleus to decay. For example, you start with a sample of 1000 Oxygen-15 (15O) nuclei, which has a half-life of 122 seconds. After 122 seconds, half of the 15O nuclei will have decayed into Nitrogen-15 (15N) nuclei. After another 122s, half of the remaining Oxygen nuclei will have also decayed, and so on. Suppose you start with 3.71×10315O nuclei...

The half-life of a reaction, t1/2, is the time required for one-half of a reactant to be consumed. It is the time during which the amount of reactant or its concentration decreases to one-half of its initial value.Determine the half-life for the reaction in Part B using the integrated rate law, given that the initial concentration is 1.95 mol⋅L−1 and the rate constant is 0.0019 mol⋅L−1⋅s−1
