Textbook Question
Chapter 13, Problem 128RQ
Radioactive samples are considered to become nonhaz- ardous after 10 half-lives. If the half-life is less than 88 days, the radioactive sample can be stored through a decay-in-storage program in which the material is kept in a lead-lined cabinet for at least 10 half-lives. What percent of the initial material will remain after 10 half-lives?
