protactinium-233
isotope
Quick Summary
Protactinium-233 is a synthetic, radioactive isotope of protactinium, a chemical element in the actinoid series with atomic number 91. It is produced when thorium-232 is irradiated with neutrons, converting it to thorium-233, which then decays into protactinium-233. This isotope is significant because it is the precursor to uranium-233, a fissile isotope of uranium that is important in the production of nuclear fuel. Protactinium-233 itself decays via beta emission to form uranium-233.12
