Abstract: The present invention is to provide a device for activating a substance, which is a flexible sheet that is available regardless of the shape of each of the device that has a substance to be activated inside. The member for activating a substance 1 of the present invention is flexible. The member for activating a substance 1 includes a metal layer 11 containing a metal with a redox potential of 0 V or less or an alloy of a metal with a redox potential of 0 V or less and a radiation generating layer 12 containing a mixture of a natural ore containing a radioactive substance with a radiolucent resin. The dose of radiation generated from the radiation generating layer 12 is from 0.02 ?Sv/h or more to 0.2 ?Sv/h or less. To enhance the flexibility, a radiation shielding layer that shields radiation generated from the radiation generating layer 12 is preferably unformed.

Abstract: The present invention is to provide a member for reducing charge for transportation that further decreases positive charge of charged transportation to contribute to improvement in driving stability and acceleration performance. The member for reducing charge for transportation 1 of the present invention is a laminated structure in which a metal layer 11 and a radiation generating layer 12 are laminated. The metal layer 11 contains a metal with a redox potential of 0 V or less or an alloy of a metal with a redox potential of 0 V or less, and the radiation generating layer 12 contains a mixture of a natural ore containing a radioactive substance with a radiolucent resin. The dose of radiation generated from the radiation generating layer 12 is from 0.02 ?Sv/h or more to 0.2 ?Sv/h or less. The member 1 is suitably used for the transportation in which the body is positively charged by static electricity caused by travelling, cruising, etc.

Abstract: The present invention is to provide apparatus for reducing charge for vehicle that is capable to decrease the charge taken by a vehicle regardless of the type of the drive source, which is more reasonable without relying on external energy supplied from, for example, a battery carried in a vehicle and which enables its small size. The apparatus for reducing charge for vehicle 1 of the present invention includes a body 10 and a conductive wire 20 that extends from this body 10. The body 10 includes a radiation generating layer 11 containing a natural ore containing a radioactive substance, a first metal layer 12 containing a metal with a redox potential of 0 V or less or an alloy of this metal, and a second metal layer 13 containing a metal with a volume electric resistance rate of 4.7 ??·cm or less at 0° C. or an alloy of this metal.
