Cross-correlated gamma ray and neutron detector

A method for detecting radiation, said method comprising:

• receiving, at a radiation detector, radiation from a radiation source, wherein the radiation detector includes an outer casing, at least one first detector configured to primarily detect gamma rays, and at least one second detector configured to primarily detect neutrons;
• detecting at least one of neutrons and gamma rays in the radiation using the at least one first detector;
• detecting at least one of neutrons and gamma rays in the radiation using the at least one second detector;
• receiving, at a computing device communicatively coupled to the at least one first detector and the at least one second detector, data from the at least one first detector and the at least one second detector;
• combining the data from the at least one first detector and the at least one second detector;
• and
• determining, using the computing device, a total detected energy spectrum and a number of neutrons and gamma rays detected based on the combined data.

A method for detecting radiation using a radiation detector that includes a computing device, the method comprising:

• receiving, at the computing device, first data from at least one first detector that is configured to primarily detect gamma rays;
• receiving, at the computing device, second data from at least one second detector that is configured to primarily detect neutrons;
• combining, using the computing device, the first and second data;
• determining, using the computing device, a number of neutrons and gamma rays detected based on the combined first and second data;
• and
• determining, using the computing device, a total detected energy spectrum based on the combined first and second data.
