Abstract
Apparatus and method for detecting subsurface radiation phenomena. An elongated support member, adapted for disposal within a wellbore traversing a subsurface formation, includes a recess along its longitudinal axis. A pad is linked to the support member. The pad is configured with a surface correspondingly shaped to fit in juxtaposition with the support member recess. The pad is adapted for movement into and out of the recess such that an exposed surface of the pad can extend away from the support member. The pad also includes one or more radiation detectors and is adapted with shielding material on its sides near the exposed surface to prevent radiation reflected from the recess from reaching the detector(s) from the area near the exposed surface.
