Krypton Isotopes are used in various medical and scientific applications. Kr-82 is used for the production of Rb-81/Kr-81m generators. Many of the stable isotopes of Krypton are used in the study of the pulmonary system. Kr-78 can be used for the production of Br-75 although production of Br-75 via Se-76 is more common. Kr-86 has been used to define the standard measure of length: 1 meter is exactly 1,650,763.73 wavelengths of this isotope. |
