Abstract
A solid scintillator member is provided in the internal space of a container. The scintillator member is an aggregate of a plurality of pellets. The internal space also confines a gas produced through the vaporization of a liquid sample containing a radioactive substance. When radiation emitted from a plurality of particles within the gas reaches the scintillator member, light is generated. That light is detected by a pair of photomultipliers. A plurality of particles may be produced outside of the container and introduced into the container.
Claims13
A radiation measurement method comprising:
- a state formation step in which a liquid sample containing a radioactive substance is vaporized to generate gas containing a plurality of particles, and the gas is confined along with a solid scintillator member in a space isolated from the outside environment, to form an interaction state;
- and
- a detection step in which light generated on the scintillator member due to radiation from the plurality of particles in the interaction state is detected.
A radiation measurement apparatus comprising:
- a vaporizer unit that vaporizes a liquid sample containing a radioactive substance to generate gas containing a plurality of particles;
- a container that stores a solid scintillator member and the gas;
- and
- a detector that detects light generated on the scintillator member due to radiation from the plurality of particles.
