4. The fluorine-18 isotope is radioactive (decays by positron emission). It is used in in the form of sodium fluoride in hospitals to perform bone scans. The half-life of 1 8F is 1.9 hours. What is the rate constant for the decay of 1 8F ? If a bone scan takes about a day, what fraction of the original 1 8F isotope would remain after 7.6 hours? Iwont
