Polonium-210 is an alpha-particle emitter with a half-life of 138 days. Static-eliminator brushes for cleaning dust from camera lenses contain a small amount of 210Po at the base of the bristles. Suppose you are in charge of maintaining inventory at a camera store and you are offered a very good buy on a three-year supply of brushes. Should you maintain a stock this size? Consider how much 210Po is left at the end of each year during this period to help you decide.
