- KERMA K)inetic E)nergy R)eleased in MA)terial. ko FACTOR In activation analysis , the ratio of the product of atomic weight, isotopic abundance of activated nuclide, abundance of gamma-ray being measured, and the 2200 m/s cross section for an analyte element and a monitor nuclide. Its use in the ko method enables independence from irradiation conditions (thermal-to-epithermal ratio) and from counting conditions. The factor can be determined experimentally or from tabulated constants. KE.
- K-ELECTRON CAPTURE Radioactive decay of a nucleus by electron capture in which the electron captured by the nucleus was originally in the K-shell (1s atomic orbital). keV kiloelectronvolt; 103 electronvolts.
- KRYPTONATES A solid compound or metal into which 85Kr has been incorporated by ion bombardment or thermal
