Nuclear medicine often uses radioactive samples as a tracer to monitor processes inside the body. Suppose a nuclear reactor makes a certain isotope sample with an initial activity of 147 mCi, and the sample gets delivered to a hospital 14.0 hours later, when its activity has become 56.0 mCi. Luckily, the sample remains usable until its activity drops below 12.9 mCi. How long after the delivery is this sample usable? Submit Answer Tries 0/2
