Abstract

PURPOSE:To obtain a strength curve of a radiation in a short times without any mechanical scanning by measuring in order the radiation incident on the sensitive zone of a detector as a pulse signal having a delay time through whole zone. CONSTITUTION:A plurality of electrodes 4 provided on a substrate 3 are connected with delay elements 5 respectively in series. When the radiation is incident on a position x where the detector 11 is placed, an atmosphere close to a high tension wire 10 discharges electrons and positive ions, said positive ions being attracted to the electrodes. At the same time, an electron avalanche phenomenon corrus and an ionization amplification is caused. The electron is influenced by an electric field and is detected by the electrode 4 as a current pulse. The pulse occurs in proportion to the strength of the radiation and flows to the both ends of the delay element 5 as current respectively.
