This Article contains an error in Figure 7, in which Panel A was a duplication of Panel B. The correct Figure 7 appears below as Figure 1. (Figure presented.) Additionally, this Article contains typographical errors in the Introduction: “Alpha radiation, one form of Ionizing radiation, is a stream of doubly charged particles and is emitted from radioactive decay of a heavy nucleus, D-T or D-D reactions1.” should read: “Alpha radiation, one form of Ionizing radiation, is a stream of doubly charged particles and is emitted from radioactive decay of a heavy nucleus and D-T reaction1.” “In a neutron generator utilizing D-D to D-T reaction for emission of monoenergetic neutrons for nuclear material interrogation purpose, monitoring of alpha radiation generated in opposite to neutrons is used for associated particle imaging2.” should read: In a neutron generator utilizing D-T reaction for emission of monoenergetic neutrons for nuclear material interrogation purpose, monitoring of alpha radiation generated in opposite to neutrons is used for associated particle imaging2.” © 2020, The Author(s).
