You are training for an upcoming Physics Olympics competition. Your coach gives you the following problem and a short time interval to solve it: For radioisotopes with very long half-lives, we cannot measure the half-life in the laboratory, because the activity does not change enough in a reasonable time interval to generate a graph like in the figure below. N(1) Nor No N=Noe The time interval T₁/2 is the half-life of the sample. T1/2 271/2 Ⓡ But suppose you have been given a sample of pure 115In that has been gathered from meteoroids. The sample has a mass of 94.1 g and has a measured activity of 24.5 Bq. Quick! Determine an estimate f the half-life of 1151n (in years).

U-235 has a decay constant of 3.138 × 10¹7 s¹. Calculate the ratio of U-235 remaining after 500 million years.
Two radioactive isotopes, X and Y, both decay to stable products. The half-life of X is about aday, while that of Y is about a week. Suppose a radioactive sample consists of a mixture of thesetwo nuclides. If the mixture is such that the activities arising from X and Y are initially equal,then a few days later the activity of the sample will be due ………………………………… .i. predominantly to X.ii. predominantly to Y.iii. to X and Y equally.iv. entirely to Y.
Potassium-argon dating is used to measure the age of rocks formed from cooled lava by determining the fraction of the original 40K remaining in a sample from the ratio of 40K:40Ar. Unusually, potassium-40 decays into both 40Ca (89.1% of the time) and 40Ar (10.9% of the time) with a half-life of 1:248 x 10^9 years. 1. Write out balanced nuclear equations for these two decay processes. 2. Calculate the specific activity of 40K.
At t = 0 we begin to observe two identical radioactive nuclei that have a half-life of 5 min. At t = 1 min, one of the nuclei decays. Does that event increase or decrease the chance that the second nucleus will decay in the next 4 min, or is there no effect on the second nucleus? (Are the events cause and effect, or random?)
