A spinthariscope is a scientific instrument designed to detect and visualize alpha particles, which are emitted during the radioactive decay of certain materials. The device typically consists of a small tube that contains a phosphorescent material at one end and a source of alpha radiation, such as a small sample of a radioactive isotope, at the other end.
