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 WebExamples of common radionuclides that emit gamma rays are technetium-99m (pronounced tech-neesh-e-um, the most commonly used radioactive material in nuclear medicine), iodine-125, iodine-131, cobalt-57, and cesium-137.
