It is shown that inelastic interaction of muons in cosmic rays corresponds in practice to a photoproduction process (Q/sup 2/ approx. = 0.1 GeV/sup 2/). The results of an experiment performed with an ionization calorimeter point to constancy of the photonuclear cross section on iron nuclei, sigma/sub ..gamma../ = 4.1 +- 0.3 mb, up to energies 10/sup 12/ eV. Comparison with accelerator data on the photonuclear cross section (sigma/sub ..gamma..N/ = 100 ..mu..b) yields for the shadow effect a value A/sub eff//A= 0.73 +- 0.06, which agrees with the ..gamma..-ray data at approx. 10 GeV.
