Correction factors are needed when an Neutron Rem Detector (NRD) aka "Remball" is used in close proximity to a points source. This formula is per ISO ISO 8529-2-2000 section 6.2. Note, however, that the ISO formula predicts the response. The formula used here takes the inverse to correct for the over-response.
neutron_geom_cf(l, r.d, del = 0.5)
The distance from the center of the detector to the center of the source. Units of l and r.d must be consistent.
The detector radius. Value for typical NRD is 11 cm. An example is also provided with a Rem 500 detector with a radius of 4.5 cm.
The neutron effectiveness factor, default per ISO.
The correction factor for solid angle.
