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 bleeding, and to label platelets to study their survival.
Chromium also has two metastable nuclear isomers. [9] The primary decay mode before the most abundant stable isotope, 52 Cr, is electron capture and the primary mode after is beta decay. [9] 53 Cr is the radiogenic decay product of 53 Mn (half-life 3.74 million years). [24] Chromium isotopes are typically collocated (and compounded) with ...
This page uses the meta infobox {{Infobox isotopes (meta)}} for the element isotopes infobox.. This infobox contains the table of § Main isotopes, and the § Standard atomic weight.
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

From 1 October 2015 to 6 April 2016, the Dubna team performed a similar experiment with 48 Ca projectiles aimed at a mixed-isotope californium target containing 249 Cf, 250 Cf, and 251 Cf, with the aim of producing the heavier oganesson isotopes 295 Og and 296 Og. Two beam energies at 252 MeV and 258 MeV were used.
Example: copper in terrestrial sources. Two isotopes are present: copper-63 (62.9) and copper-65 (64.9), in abundances 69% + 31%. The standard atomic weight (A r °(Cu)) for copper is the average, weighted by their natural abundance, and then divided by the atomic mass constant m u.
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
