Title: Material for measuring amount of radiation of electron ray
Inventor: YANAGI MASATO
IPC: G01T1/04
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To sensitively, safely, and easily display the amount of radiation of electron rays according to the clear change in hue by carrying a coloring matter that changes color due to reaction with a radical and/or a coloring matter precursor in a carrying body. SOLUTION: In a radial generation agent used for a measurement material, the amount of generated radical is prescribed by the amount of radiation of electron rays, and the color of a coloring matter and/or a coloring matter precursor is changed by the reaction with the generated radical. More specifically, a material for generating the radical due to the application of electrons rays can be used as a radical generation agent. Concretely speaking, in an organic compound with a normal carbon-carbon bond, the bond is disconnected by an electron being accelerated by a specific acceleration voltage, thus generating a radical at the cutting end. Therefore, although an organic compound in general may be used as the radical generation agent, for example, an organic halide and azide are preferable in terms of such factors as the quantum efficiency and safety for generating the radical.
