Latest Patents
One of his latest inventions is a radioactivity measuring apparatus using optical fiber. This elongated, thinner apparatus is designed to measure surface contamination in narrow places and piping. It features an elongated plate-shaped radioactivity detection section equipped with a scintillator and a radioactivity measuring section connected via a wavelength conversion optical fiber cable. The measurement signal of α-rays detected by the radioactivity detection section is transmitted to the measuring section through this optical fiber cable. The design includes elongated light guides, sets of wavelength conversion optical fibers, a scintillator layer, and a light-shielding film, all surrounded by a light-shielding frame to ensure accurate measurements.
Another notable patent is a radioactive dust monitor. This device comprises a dust collecting electrode that also serves as a radiation detecting surface, along with an ionization line that extends in air, spaced from the dust collecting electrode. The radiation detection part includes a scintillator positioned close to the dust collecting electrode and a photoelectric conversion part that converts light emitted from the scintillator into an electric signal. The monitor effectively collects dust in the air through a corona discharge, allowing for the detection of radioactive rays emitted from the collected radioactive dust.
