Abstract: For providing a composition for ionizing radiation determination that realizes determination of absorbed dose simply in enhanced quantitative manner while avoiding any influences from visible light, ultraviolet rays, etc. with the use of a composition for determination of ionizing radiation absorbed dose being highly responsive to ionizing radiation, there is provided a composition for determination of ionizing radiation absorbed dose containing a material capable of coloring or discoloring upon exposure to ionizing radiation, characterized by further containing zinc oxide.

Abstract: The present invention provides a nickel compound-containing solution having suitability for screen printing, and a method of forming a nickel metal thin film comprising applying the nickel compound-containing solution by screen printing. In a nickel compound obtained by reacting a reducing compound with nickel salt of organic acid, a nickel compound-containing solution, in which a nickel compound is stable and dissolved in terpineol, can be provided by using the specific structure compound as the reducing compound. This solution or the solution further containing resin such as cellulose and the like has the viscosity suitable for screening printing. A nickel metal thin film can be formed by applying the nickel compound-containing solution onto a substrate with screen printing and then heat-treating.
