Abstract

An arrangement (100) for detecting different ionizing radiations, such as radioactivity and galactic cosmic rays, comprises by a mass spectrometer (101) and an ionization tube (102) with a carrier gas, which is adapted to enable ionizing reactions (104) between the ionizing radiations (105) and the carrier gas and thereby enabling formation of ion particles. The arrangement comprises also a flow tube (107) for providing the carrier gas flow through the ionization tube (102). The arrangement is configured to introduce the carrier gas with said produced ion particles to the mass spectrometer (101) for detection (109) existence of said ionizing radiations (105) or other particles (106) to be detected.
