Spectral neutron fluence at workplaces

The main objective of this collaborative project was to produce in the laboratory a few well characterised neutron fields that replicate typical spectral fluence distributions encountered in radiation protection practice. The project consisted of four distinct parts, namely:
the measurement of typical spectral neutron fluences encountered in practise;
the preparation of a catalogue of measured neutron spectra, reponse functions to neutron detectors adn dosimeters commonly used, and various fluence to dose conversion functions;
the development of a program system for using this catalogue (eg to calculate dosimetric quantities fo the fields, estimate readings of detector systems and to derive the requirements for realistic calibration fields;
the computational prediction of configurations consisting of easily accessible neutron sources and appropriate moderators, and the realization of these basic fields in the laboratory.

Considerable progress has been achieved in neutron dosimetry within the framework of this project.
