Iodine 131 and iodine 125 are emitter of
WebIodine-131 is a beta and gamma emitter. The energies of both are significant, so quite high dose rates are emitted by this nuclide, and the gamma radiation is quite penetrating. The half-life is 8 days, so over the likely period of use of the material, there is not a large reduction in activity. There can therefore be Web25 feb. 2016 · Both I-131 and I-125 are radioactive isotopes of naturally occurring I-127. I-131 is highly radioactive and gives of energy in both beta and gamma radiation. I-131 has a half-life of 8 days and decays into stable Xenon 131. Created by nuclear fission of either uranium or plutonium. Structure of the Compound and Physical Properties continued
