| 摘要 |
A gamma ray detector assembly for placement in a logging tool in a borehold can include a first gamma ray detector elongated along an axis and having a void extending along the axis. A second gamma ray detector conforms to at least a portion of the void. The first and the second gamma ray detectors are configured to be positioned in the borehole. |
