Krypton is used in the fanciest, most energy-efficient double-pane insulated windows. Krypton is also used in certain fluorescent lamps and in a flash lamp employed in high-speed photography. Radioactive krypton-85 is useful for detecting leaks in sealed containers, with the escaping atoms detected by means of their radiation.
