  1. Suppose that on average atoms of a particular radioactive isotope decay to atoms of a stable isotope in 2 minutes.

    1. (a) Let T1 and T2 be the independent decay times of two radioactive atoms in a sample. Compute the cdf of M := max{T1, T2}.

    2. (b) If a sample is known to contain 3 radioactive atoms with independent decay times, what is the probability that the sample will still be radioactive in 4 minutes?

The 238U nucleus has a relatively complicated radioactive decay sequence until it becomes a stable 206Pb nucleus. The questions below should help you understand why this sequence is not a simple series of alpha decays, but involves both alpha and beta-minus decays. How many protons and how many neutrons must be removed from the unstable 238U nucleus to decay into a stable 206Pb nucleus? 1)How many protons and neutrons? 2) Find the minimum, actual, and extra number of alpha decays...

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 4.00×103 15O...

Suppose that on the average the number of particles emitted from a radioactive substance is five per second. What is the probability that it will take less than 3 seconds for the next two particles to be emitted? A beam of length 1 , rigidly supported at both ends, is hit suddenly at a random point, which leads to a break at a position X from the right end. If the distribution of X is beta, with =4,  β=2 , what...
