1. A neutron detector comprising:
- two or more memory dies comprising a plurality of memory cells, the memory dies comprising neutron-reactant layers over the memory cells; and
one or more gamma shields over at least a portion of or an entire of the two or more memory dies, the gamma shield substantially preventing gamma rays from penetrating into the memory die under the gamma shield.

Abstract
Neutron detectors including one or more gamma shields over memory dies and methods of making the neutron detectors are provided. The neutron detectors can contain two or more memory dies, neutron-reactant layers over the two or more memory dies, and one or more gamma shields over at least a portion of or an entire of the two or more memory dies. By containing the gamma shield over the at least a portion of or an entire of the two or more memory dies, the neutron detector can detect and discriminate neutrons in the presence of gamma rays.

17. A method of detecting strength of a neutron field, comprising:
-
providing a neutron detector comprising two or more memory dies, neutron-reactant layers over the two or more memory dies, and one or more gamma shields over at least a portion of or an entire of the two or more memory dies, the memory die comprising a plurality of memory cells, the gamma shield substantially preventing gamma rays from penetrating into the memory die under the gamma shield; reading a state of each of the memory cells of the memory dies to determine a number of memory cells changing from an initial state to a disturbed state; and determining the strength of the neutron field by using the number of memory cells having the disturbed state. - View Dependent Claims (18, 19, 20)
