Absolute measurement of the neutron sensitivity of a ZP1320 geiger-Müller counter using the associated-particle technique.

Because of their low neutron sensitivity Geiger-Müller counters are often used in mixed-field dosimetry to determine the photon dose fraction. The associated-particle technique has been used to determine absolutely the neutron sensitivity of an energy-compensated ZP1320 Geiger-Müller counter at 3 MeV. The measurement is consistent with previous measurements using this type of counter.
