Abstract :
A new neutron dose monitor for the measurement of pulsed neutron fields was designed and tested. The concept is based on high energy neutrons activating on 12C target nuclei in the detector materials short-lived radioactive nuclides. The new system comprises two different detectors to measure simultaneously neutrons and charged particles from the decay of instable intermediate nuclear states: a 3He proportional counter tube in a moderator and a plastic scintillator with a photomultiplier. The decay products are detected in time-resolved readout. Analysis of the time distributions provides dose information free of dead time.
