Understanding the role of krypton gas in window insulation

Krypton gas is an inert gas used to insulate double and triple glazed windows. The gas is injected between the panes, reducing conductive and convective heat transfer and increasing the thermal efficiency of the window. The high cost of krypton gas is offset by its superior insulating properties, making it a preferred choice for high performance windows.

Krypton gas in the lighting industry

Krypton gas is used in lighting, particularly in fluorescent lamps and flash photography. When an electric current is passed through krypton, it emits a brilliant white light, making it useful for many lighting applications. This property of krypton has led to its widespread use in industries requiring high intensity lighting.

Use of krypton in medicine

Krypton-81m is a radioactive isotope of krypton used in diagnostic medicine. It is an excellent lung ventilator used in nuclear medicine for scanning and imaging. Krypton-81m allows physicians to assess lung function and diagnose diseases such as emphysema and chronic obstructive pulmonary disease (COPD).
