A radiation detector includes a pressure-tight housing having a peripheral, cylindrically-shaped wall and opposite end closures. An electrode wire extends through a center of the housing, spaced from the cylindrically-shaped wall. A pressurized detector gas fills the housing, and circuit connections to the electrode wire and the housing permits application of an electric potential thereto. The electrode wire is composed of a material providing a source of alpha particles for ionizing the gas within the housing, generating an alpha peak on the output spectrum distinct from the peak generated by incident neutrons. A related method is also disclosed.
