From a chemistry perspective, the lag time associated with microwave popcorn would give poor data for a half-life curve. The half life is not simply the time it takes for half the sample to decay, but is a representation of the random nature of radioactivity. It is usable for predicting how many isotopes will remain, even when it has not reached a full half life yet! The curve should be an exponential decay, which you will not get very well with popcorn.
