The availability of active neutron personal dosimeters has made real time monitoring of neutron doses possible. This has obvious benefits, but is only of any real assistance if the dose essessments made are of sufficient accuracy and reliability. Preliminary assessments of the performance of active neutron dosemeters can be made in calibration facilities, but these can never replicate the conditions under which the dosemeter is used in the workplace. Consequently, it is necessary to assess thier performance in th workplace, wihich requires the field in the workplace to be fully characterised in terms of the energy and direction dependence of the fluence. This paper presents an overview of developments in workplace neutron dosimetry but concentrates on the outcomes of the EVIDOS project, which has made significant advance in the characterisation of workplace fields and the analysis of dosimeter response in those fields.
