Abstract
In accordance with an illustrative embodiment of the present invention, apparatus for furnishing a desired borehole environment in nonfluid-filled borehole logging operations when radioactivity logging methods are being employed includes a member covering a portion of a sonde, which portion has at least one radiation detector. The member is fabricated of a material selected to simulate a particular borehole environment and is arranged for attachment to the sonde to prevent longitudinal and rotational movement therebetween. The outer surface of the member conforms generally to the borehole.
