WebDec 5, 2012 · If bombarded with neutrons, isotopically pure 232 Th forms 233 Th, which has a half-life of 22 minutes and β-decays to 233 Pa. That isotope has a half-life of 27 days and β-decays to... The most stable isotope is 231 Pa with a half-life of 32,760 years, 233 Pa with a half-life of 26.967 days, and 230 Pa with a half-life of 17.4 days. All of the remaining radioactive isotopes have half-lives less than 1.6 days, and the majority of these have half-lives less than 1.8 seconds. See more Protactinium (91Pa) has no stable isotopes. The four naturally occurring isotopes allow a standard atomic weight to be given. Twenty-nine radioisotopes of protactinium have been … See more Protactinium-230 has 139 neutrons and a half-life of 17.4 days. Most of the time (92%), it undergoes beta plus decay to Th, with a minor (8%) beta-minus decay branch leading to See more Protactinium-233 is also part of the thorium fuel cycle. It is an intermediate beta decay product between thorium-233 (produced from natural thorium-232 by neutron capture) and uranium-233 (the fissile fuel of the thorium cycle). Some thorium-cycle … See more Protactinium-231 is the longest-lived isotope of protactinium, with a half-life of 32,760 years. In nature, it is found in trace amounts as part of the See more Protactinium-234 is a member of the uranium series with a half-life of 6.70 hours. It was discovered by Otto Hahn in 1921.

WebThe Pa-233 (half-life of 27 days) decays into U-233. Some U-232 is also formed via Pa-232 along with Th-233, and a decay product of this is very gamma active. MSRs would … WebPa-233 U-233 Thorium-233 decays quickly (half-life of 22.3 min) to protactinium-233 by emitting a beta particle (an electron). Protactinium-233 decays more slowly (half-life of 27 days) to uranium-233 by emitting a beta particle (an electron). It is important that Pa-233 NOT absorb a neutron before it decays to U-233—it should be WebProtactinium-233 with half-life of 27 days is used as neutron poison because of its high cross section for neutron capture.
