Abstract
A measuring device includes an ionization chamber where air is contained and a measurement value relating to radiation including a neutron ray and a gamma ray is measured, a detector that detects a detection value relating to the neutron ray, and a controller that calculates a dose of the gamma ray based on the measurement value measured in the ionization chamber and the detection value detected by the detector.

A measuring method comprising:
- calculating, based on a measurement value relating to radiation including a neutron ray and a gamma ray, which is measured in an ionization chamber containing air inside, and a detection value relating to the neutron ray, which is detected by a detector, a dose of the gamma ray.
A measuring system comprising:
- a radiation therapy apparatus that emits radiation including a neutron ray and a gamma ray;
- and
- a measuring device including:
- an ionization chamber where air is contained and a measurement value relating to the radiation including the neutron ray and the gamma ray is measured,
- a detector that detects a detection value relating to the neutron ray, and
- a controller that calculates a dose of the gamma ray based on the measurement value measured in the ionization chamber and the detection value detected by the detector.

A radiation therapy system comprising:
- a radiation therapy apparatus that emits radiation including a neutron ray and a gamma ray;
- and
- a measuring device including
- an ionization chamber where air is contained and a measurement value relating to the radiation including the neutron ray and the gamma ray is measured,
- a detector that detects a detection value relating to the neutron ray, and
- a controller that calculates a dose of the gamma ray based on the measurement value measured in the ionization chamber and the detection value detected by the detector,
- wherein the radiation therapy apparatus controls the emission of the radiation by using the dose of the gamma ray calculated by the measuring device.
