SUMMARY
The discussion focuses on calculating the expected ratio of two radioactive isotopes, A and B, after 8 hours, given their half-lives of 2 hours and 4 hours, respectively. Starting with an equal initial quantity of both isotopes (1:1 ratio), the calculation utilizes the formula N = No*(1/2)^(t/T) to determine the remaining quantities after each half-life. After 8 hours, isotope A will have undergone four half-lives, reducing its quantity to 1/16 of the original, while isotope B will have undergone two half-lives, reducing its quantity to 1/4 of the original. The final ratio of A to B after 8 hours is 1:4.
