摘要： A light detecting unit of an alpha ray observation device observes an alpha ray by measuring generated light that is generated by the alpha ray produced in a region of a to-be-measured object. The light detecting unit has a travel direction changing unit that changes the direction of travel of generated light, a light detector that detects direction-changed light, which is the generated light after the direction of travel is changed, and a shielding member that shields the light detector from radiation and has a portion that is provided on the line from the to-be-measured object to the light detector. The shielding member may also surround the perimeter of the light detector and have an opening to allow generated light to reach the travel direction changing unit.
