Abstract: A method of minimizing the orientation dependence of an automatic drift compensation of a scintillation counter having a rod-shaped scintillator is provided. The cosmic radiation energy spectrum is analyzed above a predefined energy threshold value for the automatic drift compensation. A counting rate of particles having an energy deposition in the scintillator greater than an energy threshold value is controlled to a constant desired counting rate value. The method determines a first integral energy spectrum of the cosmic radiation while the scintillator is upright, and a second integral energy spectrum while the scintillator is in a horizontal position. An intersection point of the first and second integral energy spectrums is detected, and the energy threshold value of the drift compensation is set to the energy threshold value pertaining to the intersection point and the desired counting rate value is set to the counting rate pertaining to the intersection point.

Abstract: A system for measuring ionizing radiation with a scintillator incorporates a first assembly of at least two rod-shaped scintillator elements, which can be optically coupled to one another via their opposed face ends. The first assembly of scintillator elements is coaxially enclosed by a second assembly of interconnectable sheath elements. According to the invention, one scintillator element (11), one sheath element (12) and two face-end window elements (131, 132) form a scintillator module (10) in each case, which is optically and mechanically connectable to additional scintillator modules. The individual scintillator elements can thus be produced as encapsulated scintillator modules by means of “suitable” sheath elements and window elements. This provides for a simple and reliable manipulation and assembly of the measuring assembly at the site of its application.
