<P>PROBLEM TO BE SOLVED: To provide a composition for applying weak radiation capable of safely and efficiently amplifying quantity of radiation actually applied to a target object without increasing the quantity of radioactive material. Ž<P>SOLUTION: The composition for applying weak radiation includes weak radioactive material releasing weak radiation, radiation amplifying material amplifying the quantity of radiation to the target object in a range where human body does not receive harmful influence, and forming material. Since attenuation of quantity of radiation can be kept at the minimum by antenna effect of the radiation amplifying material by using a material containing carbon having a fiber shape, a string shape, a needle shape or a bar shape and having a grain length of 0.01-10 mm as the radiation amplifying material, radiation can be very efficiently applied to the target object.
