| 1. A material activating device comprising: (i) a radioactive layer of a radioactive means that emits radioactive rays for
irradiating a material to be activated, (ii) a conductive metal layer disposed on one side of the radioactive layer of the
radioactive means so as to be interposed between the radioactive layer of the radioactive means and the material to be activated,
and (iii) a base member;
wherein the conductive metal layer is the wall of a hollow casing of a conductive metal,
the radioactive layer of the radioactive means is disposed inside the casing, and the base member is made of a conductive
metal, closely attached to the casing and designed to be attached to the material to be activated, and is formed by nesting
a plurality of polygonal, annular members.
