A propylene polymer composition containing (i) 100 parts by weight of a polypropylene and/or a propylene-ethylene copolymer and (ii) 0.05 to 2 parts by weight of triallyl(iso)cyanurate and/or diallyl(iso)phthalate, or (i) 100 parts by weight of a polypropylene and/or a propylene-ethylene copolymer, (ii) 0.01 to 0.5 part by weight of triallyl(iso)cyanurate and/or diallyl(iso)phthalate, and (iii) 0.005 to 0.2 part by weight of an organic peroxide. This propylene composition has excellent resistance against high-energy radiation without impairing the desired properties of the propylene polymer per se.
