Iodine-131 is a decaying radioisotope that produces xenon-131 through beta decay. During beta decay, a neutron is transformed into a proton within the nucleus, and a beta particle (an electron) is emitted, resulting in the production of xenon-131.
A PET scan uses radioisotope decay by detecting the pair of annihilation photons emitted during the decay process.
How long it takes for half of a sample to decay to another form.
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.
