A moderated neutron detector includes a neutron detector having a first volume. A moderating enclosure is positioned around the neutron detector and encloses a second volume. The second volume is between 2 and 80 times larger than the first volume. A method for increased neutron detection includes the following steps: positioning a neutron detector within a moderating enclosure, wherein the neutron detector has a first volume, wherein the moderating enclosure encloses a second volume, and wherein the second volume is between 2 and 80 times larger than the first volume; increasing a quantity of neutrons impingent upon the neutron detector; and measuring the quantity of neutrons impinging upon the neutron detector.
