Centronic boron ion chambers can be tailored to measure neutron fluxes over the range required for the application.
Uncompensated boron ion chambers are generally used in regions of high neutron flux where the gamma field, which will also contribute to the output measurement, is not significant in relation to the neutron flux. The most common application of uncompensated boron ion chambers is therefore in reactor control detectors for operation at full reactor power.
Gamma compensated boron ion chambers are also available for use in reactor control instrumentation. These are more suited to high mixed fields (neutron and gamma) found near a reactor, being capable of compensating for gamma fluxes in these environments. Compensation for the gamma flux allows this type of device to operate at lower neutron flux levels.
