摘要

The physical quantity of neutron flux can be measured indirectly through interaction signals between the neutron and the material used as a neutron detector, as discussed in Chap. 5 . To determine neutron flux, the measured reaction rate obtained in the experiments should be used. Acknowledging that it is not easy to determine neutron flux using the reaction rate, this chapter focuses on the theory of reactor physics related to neutron flux and discussion of radiation measurement techniques to determine neutron flux.
