1. A device for detecting radiation, comprising:
a first electrode having a first plurality of fingers comprising a nanotube material;
a second electrode having a second plurality of fingers comprising a nanotube material, the second plurality of fingers being interdigitated with the first plurality of fingers;
a voltage source configured to apply a voltage across the first and second electrodes;
a chamber containing the first and second electrodes and a gas, at least one wall of the chamber enabling passage of radiation external to the chamber; and
a detection circuit configured to detect 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.
