Iodine-135 is an isotope of iodine with a half-life of 6.6 hours. It is an important isotope from the viewpoint of nuclear reactor physics . It is produced in relatively large amounts as a fission product , and decays to xenon-135 , which is a nuclear poison with the largest known thermal neutron cross section , which is a cause of multiple ...
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.
For this reason, Iodine is often considered for transmutation despite the presence of stable 127 I in spent fuel. In the thermal neutron spectrum, more Iodine-129 is destroyed than newly created since Iodine-128 is short lived and the isotope ratio is in favor of 129 I. Depending on the design of the transmutation apparatus, care must be taken ...

Isotope Halflife Comment 6.7896%: Caesium: 133 Cs → 134 Cs: 2.065 y: Neutron capture (29 barns) slowly converts stable 133 Cs to 134 Cs, which itself is low-yield because beta decay stops at 134 Xe; can be further converted (140 barns) to 135 Cs. 6.3333%: Iodine, xenon: 135 I → 135 Xe: 6.57 h
According to Jiri Hala's textbook, [14] the radioactivity in the fission product mixture in an atom bomb is mostly caused by short-lived isotopes such as iodine-131 and barium-140. After about four months, cerium-141 , zirconium-95 / niobium-95 , and strontium-89 represent the largest share of radioactive material.
