Radioactive substance detection device

Abstract

The present invention addresses the problem of providing a safe, easy-to-handle, highly sensitive radioactive substance detection device as well as a radioactive substance detection device and method capable of detecting an α-emitting analyte directly, simply, and inexpensively. The following is provided, as a solution, [1] a radioactive substance detection device including a capillary for retaining a radioactive substance and a solvent inside the capillary, and a light detecting means, wherein the light detecting means is configured to detect Cherenkov light-containing light generated when radiation emitted from the radioactive substance penetrates the solvent and/or a tube wall of the capillary; and [2] a radioactive substance detection device including a light detecting means, wherein the radioactive substance contains at least one α-emitting nuclide, and the light detecting means is configured to detect light generated when an α-ray emitted from the radioactive substance comes into contact with at least one selected from the group consisting of glass, fluorescent indicator F254, and fluorescent indicator F254S.
