Abstract
For use in a sonde adapted to be lowered in a well bore, the present apparatus sets forth an improved nuclear event detector. The detector is sized and shaped monotonically increasing in cross section or diameter with increasing distance from the radiation source to thereby bias the detector; this bias counteracts the bias arising from geometry altering the pattern in which nuclear events impinge on the detector, thereby altering the distribution of such events.
