Krypton-85 has a half-life of about 10.75 years. This isotope is produced by the nuclear fission of uranium and plutonium in nuclear weapons testing and in nuclear reactors, as well as by cosmic rays.

Jun 26, 2024 · Krypton-85 is a radioactive isotope with a half-life of approximately 10.76 years. It decays by beta emission, transforming into stable rubidium-85 and in the process it also releases a gamma ray with an energy of 514 keV.

Krypton-85 (Kr-85) is a radioactive isotope of krypton with a half-life of approximately 10.7 years. It decays by beta emission, producing stable rubidium-85 (Rb-85). Kr-85 also emits low-energy gamma radiation, making it detectable through gamma spectrometry.

Krypton-85 is the isotope of concern at Department of Energy (DOE) environmental management sites such as Hanford. It is produced by the fissioning of uranium and plutonium and is present in spent nuclear fuel. The low specific activity of krypton-81 limits its radioactive hazards.

The term radioactive kryptonates is used for substances into which atoms or ions of krypton-85 (85 Kr) are incorporated (by diffusion of 85Kr, by bombardment with accelerated krypton ions, by introduction of 85 Kr during sample preparation, byphase transition, etc.).

Dec 30, 2024 · Technical means available for the retention of 85Kr and its immobilization, storage and disposal are reviewed. Cryogenic processes for the separation of krypton and xenon from diluting gases are discussed in more detail.
