1. A well-logging apparatus comprising:
- a housing to be positioned within a borehole of a subterranean formation;
at least one radiation source carried by said housing to direct radiation into the subterranean formation;
a plurality of noble gas-based radiation detectors carried by said housing in azimuthally spaced relation to detect radiation from the subterranean formation; and
a controller to determine at least one property of the subterranean formation based upon the detected radiation from the plurality of noble gas-based radiation detectors.

Abstract
A well-logging device may include a housing to be positioned within a borehole of a subterranean formation, and at least one radiation source carried by the housing to direct radiation into the subterranean formation. The well-logging device may also include noble gas-based radiation detectors carried by the housing in azimuthally spaced relation to detect radiation from the subterranean formation. A controller may determine at least one property of the subterranean formation based upon the detected radiation from the noble gas-based radiation detectors.
