After evaluating various γ-emitters for their study, Pound and Rebka chose to use Fe because it does not require cryogenic cooling to exhibit recoil-free emission, has a relatively low internal conversion coefficient so that it is relatively free of X-ray emissions that would have been difficult to distinguish from the 14.4 keV transition, and its parent Co has a usable half-life of 272 days.
