Radiation detector, arrangement and method for measuring radioactive radiation, where continuous low-energy background noise is reduced

摘要

The invention relates to a radiation detector, an arrangement and a method for an energy-dispersive detection of X-ray photons. X-ray photons are allowed to collide ( 701 ) in the radiation detector ( 201, 601 ), whereby there are produced ( 702, 703, 704, 705, 706, 707, 708 ) observations of the X-ray photons that collided in the detector. According to the invention, there are separately produced observations of X-ray photons ( 702, 703, 704 ) that collided in the first detector space ( 205, 501 ) of the radiation detector and X-ray photons ( 705, 706, 707, 708 ) that collided in the second detector space ( 206, 502 ) of the radiation detector. The ( 712 ) observations of X-ray photons that collided in the first detector space ( 205, 501 ) are ignored, when there is received a simultaneous observation of an X-ray photon that collided in the second detector space.
