2024年12月30日 · 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.

2024年6月26日 · 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.

2013年1月1日 · Krypton-85 is mainly produced in nuclear reactors and released during reprocessing. Krypten-85 can be possibly used as an indicator for clandestine reprocessing. This work provides an up-to-date global krypton-85 emission inventory. The inventory includes emissions from all possible artificial sources.

Krypton 85 is a radioactive isotope of the inert gas Krypton. At present it is being generated in megacurie quantities and routinely released to the atmosphere as a by-product of nuclear reactor operation and refueling.

2016年10月1日 · In this paper, the prospects of using krypton-85 emissions to detect clandestine reprocessing plants are assessed based on both present technology and possible future developments while taking into account the existing atmospheric background resulting from reprocessing activities over the past 70 years.

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.
