PROBLEM TO BE SOLVED: To obtain a container for radioactive substance which can exhibit the shielding effect depending on the source intensity ofγ-rays or neutron or the balance thereof while making compact the container and enhancing the containing efficiency by employing a single shield layer composed of a mixture, where a metal hydride is scattered into lead, on the outside of the container drum. SOLUTION:γ-rays and neutrons emitted from a radioactive substance in a container are shielded by a single shield layer 6 forγ-rays and neutrons provided on the outside of an inner drum 1. The shield layer 6 is produced as a block by scattering powder at a metal hydride into lead or compression molding the mixture of powdery lead and the powder of metal hydride. Consequently, the shield layer 6 can be provided easily by inserting the the block between the inner drum 1 and an outer drum 2. According to the arrangement, a transporter/container for radioactive substance can shieldγ-rays and neutrons effectively while enhancing the the containing efficiency.
