摘要： A Compton radiation detection device for determining of Compton radiation of iron, includes a sensor and a filter arrangement. The filter arrangement is adapted such that the radiation emitted by a test object due to Compton scattering passes a nickel layer and an iron layer before being detected by the sensor. A dispersive ionization chamber includes an ionization chamber having a plurality off ionization volumes and a window. Each ionization volume includes an electrode. Radiation can enter through the window. The ionization volumes are arranged in a beam propagation direction behind each other. Radiation having lower energy is statistically absorbed in ionization volumes located more proximal to the window. Radiation having higher energy is statistically absorbed in the ionization volumes located more distal from the window.
