How is sodium chromate Cr 51 produced?

Cr is produced in a reactor by neutron activation. It decays by electron capture, with a radioactive half-life of 27.7 days. The principal gamma-photon emission occurs by electron capture at 320 keV, slightly above the optimum detection range of standard gamma counters.

Is Chromium-51 natural?

Chromium-51 is a synthetic radioactive isotope of chromium having a half-life of 27.7 days and decaying by electron capture with emission of gamma rays (0.32 MeV); it is used to label red blood cells for measurement of mass or volume, survival time, and sequestration studies, for the diagnosis of gastrointestinal …

Is Chromium-51 naturally occurring?

Cr is suspected of decaying by β+β+ to 50Ti with a half-life of (more than) 1.8×1017 years. Twenty-two radioisotopes, all of which are entirely synthetic, have been characterized with the most stable being 51Cr with a half-life of 27.7 days….List of isotopes.
