SUMMARY —Excised pectoralis muscles of chicken received radurizing doses of γ‐radiation at varying times post‐mortem to determine the effect on shear resistance, myofibrillar fragmentation (F‐ratio) and pH. Irradiation doses between 0.1 and 0.3 Mrad produced decreases in F‐ratio and increases in shear resistance. The magnitude of the changes was directly proportional to the duration of postmortem aging prior to irradiation. Muscle pH subsequent to irradiation between 2 and 12 hr post‐mortem was not significantly affected by any of the dose‐time treatment combinations. Shear resistance and F‐ratio changes were strongly correlated on an average basis (r =+ .857; n = 6) but not on an individual sample basis.
