Abstract

A detector (9) for detection of ionizing radiation comprises a cathode (17, 41); an anode (19); an ionizable gas arranged between these electrodes; a radiation entrance (33) arranged such that ionizing radiation (1) can enter and ionize the ionizable gas; and a read-out arrangement. A voltage across the electrodes causes electrons created during ionization of the gas to drift towards the anode, where the read-out arrangement (19) detects them. To reduce the risk of occurrence of sparks, and/or to reduce the energy in occurring sparks, the cathode has at least the surface layer facing the anode made of a material having a resistivity of at least 5x10<-8> OMEGA m.
