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 ...
The iodine pit, also called the iodine hole or xenon pit, is a temporary disabling of a nuclear reactor due to buildup of short-lived nuclear poisons in the reactor core. The main isotope responsible is 135 Xe, mainly produced by natural decay of 135 I. 135 I is a weak neutron absorber, while 135 Xe is the strongest
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.

The other radioisotopes of iodine are never used in brachytherapy. The use of 131 I as a medical isotope has been blamed for a routine shipment of biosolids being rejected from crossing the Canada—U.S. border. [40] Such material can enter the sewers directly from the medical facilities, or by being excreted by patients after a treatment
Xenon-135 (135 Xe) is an unstable isotope of xenon with a half-life of about 9.2 hours. 135 Xe is a fission product of uranium and it is the most powerful known neutron-absorbing nuclear poison (2 million barns; [1] up to 3 million barns [1] under reactor conditions [2]), with a significant effect on nuclear reactor operation.
This experiment is about much more than just watching Iodine solution turn royal blue from reddish brown. Try this experiment at home with the kids to introduce them to the basic tenet of physics ...
