Neutron Detectors

it is important to note the differences between the two detectors, such as the fact that boron has a lower removal cross section (3840 barns) compared with 3He (5330 barns), therefore BF3 Counters are less sensitive than their Helium counterparts.

another difference is that the energy released per reaction is higher in 10B than 3He, which enables BF3 counters to discriminate against gamma pulses.
