Neutron dose equivalent determination in the energy range from thermal to high energy neutrons

The International Commission on Radiation Units and Measurements (ICRU) has recommended a new system of operational dose equivalent quantities for radiation monitoring. A technique for the determination of the neutron operational dose equivalent quantities is proposed using the multisphere technique and a neutron counter with a plastic polystyrene scintillator. The linear superposition of the readings of these two types of detectors allows the estimation of the neutron dose equivalent with energies ranging from thermal to hundreds of MeV. (author)
