Abstract:
A drill bit made according to one embodiment includes a source configured to induce radiation into a formation during drilling of a wellbore and a sensor in the drill bit configured to detect radiation from the formation responsive to the radiation induced by the source. The drill bit may further include a circuit configured to process signals received from the sensor to estimate a property of the formation.
