Title: Improved method and device for the measurement of ionizing radiation
IPC: H01J47/04
Filed: 1955-11-03
Abstract: 820,441. Radiation intensity measurement. SIVO A.B. Nov. 3, 1955 [Nov. 5, 1954], No. 31513/55. Class 40 (3). A device for the measurement of the ionizing radiation from a substance comprises an ion chamber 1 for the reception of the substance containing a test probe 4 together with a detachable measuring device. The probe 4 is led out of the chamber through insulating material 2 and extends into an open-ended bushing 3. A battery 5 is connected to the bushing 3 and the walls 1a of the chamber in such manner as to give the housing a negative potential. A heater 6 is provided to eliminate moisture which might cause a reduction in the insulation resistance. Measuring device 7 may have the end of its casing 7a inserted into bushing 3 and contains an insulated contact pin 9a attached to the grid 9 of a valve 8. Pin 9a may be connected with the casing 7a by means of push contact 10 and is surrounded, as shown, by a sleeve 11. A cable 12 connects the device 7 to a supply unit 13 and an adjustment unit 15. In use, the measuring device is plugged into the bushing 3 and a given bias potential of say -1.5 volts is applied to housing 7a, sleeve 11, bushing 3, and through contact 10 to the valve grid, pin 9a, and electrode 4. The radiating material is left in the chamber with the measuring device removed for a given length of time and then the measuring device is replaced in the bushing but with the pin 9a out of contact with the electrode 4. Contact 10 is closed and the initial bias state is reproduced, then contact 10 is opened and the elements 4 and 9a brought into contact. The current flow through the valve is thereby reduced and the potential that it is necessary to apply to the sleeve 11 to restore it, as indicated by the meter 16 is a measure of the radiation emitted.
