Abstract

A radiation detection device includes a sensor having a first electrode and a second electrode. The first and second electrode each defines a plurality of fingers comprising a nanotube material, and the fingers of each electrode are interdigitated with one another. A voltage source may be configured to apply a voltage across the first and second electrodes. A chamber contains the sensor with a gas, one or more walls of the chamber enabling passage of radiation external to the chamber. A detection circuit detects radiation within the chamber based on a change in current across the first and second electrodes resulting from ionization of the gas by the radiation.
