Title:
RADIATION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/095576
Kind Code:
A1
Abstract:
The present invention provides a radiation detection device in which the effective surface area and effective volume are increased but expansion of the substrate surface area is limited. Provided is a radiation detection device 100 comprising: an electrode 120 to which a prescribed voltage is applied; a substrate 110 which detects electrons generated by the interaction of radiation with a prescribed gas; and a resistor 130 which is provided between the electrode 120 and the substrate 110, wherein a concentric electric field is formed between the electrode 120 and the substrate 110 by the resistor 130 and the prescribed voltage applied to the electrode 120.
