摘要： Method and apparatus for measuring the concentration of various components, such as the iron component in iron ore, by exposing the material to irradiation between a neutron source and a gamma ray detector. The emitted gamma rays are captured by the detector and transformed into a signal which is transmitted to a recording device for measuring the gamma ray radiation.
