Curium (96 Cm) is an artificial element with an atomic number of 96. Because it is an artificial element, a standard atomic weight cannot be given, and it has no stable isotopes. The first isotope synthesized was 242 Cm in 1944, which has 146 neutrons. There are 19 known radioisotopes ranging from 233 Cm to 251 Cm. There are also ten known ...
Curium is one of the most radioactive isolable elements. Its two most common isotopes 242 Cm and 244 Cm are strong alpha emitters (energy 6 MeV); they have fairly short half-lives, 162.8 days and 18.1 years, and give as much as 120 W/g and 3 W/g of heat, respectively.
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.
Se-79, half-life of 327k years, is one of the long-lived fission products.Given the stability of its next lighter and heavier isotopes and the high cross section those isotopes exhibit for various neutron reactions, it is likely that the relatively low yield is due to Se-79 being destroyed in the reactor to an appreciable extent.
Theoretical element Applied: when element is theoretical (E119 and higher). No article "Isotopes of <element>": Header does not link; E119: Main isotopes of ununennium E121: Main isotopes of unbiunium Applied: E119, E120 do link, E121 and higher do not link. No isotopes known, Isobox does not exist: local input, per Infobox. For example:
Prolonged irradiation of americium, curium, and plutonium with neutrons produces milligram amounts of 252 Cf and microgram amounts of 249 Cf. [55] As of 2006, curium isotopes 244 to 248 are irradiated by neutrons in special reactors to produce mainly californium-252 with lesser amounts of isotopes 249 to 255. [56]
