In the nuclear industry, workers use a rule of thumb that the radioactivity from any sample will be relatively harmless after 10 half-lives. Calculate the fraction of radioactive sample that remains after this time period. What does this mean for the Rocky Flats cleanup operation, which occurred at the former Rocky Flats Plant just outside of Boulder that generated plutonium triggers for nuclear weapons ( 239 Pu decay rate
