Ratios of Hp(10) and H*(10) were termined with reference instruments in a number of workplace fields within the nuclear industry and used to derive workplace-specific correction factors. when commercial survey meter results together with these factors were applied to the results of the locally used personal dosemeters their results improved and became within 0.7 and 1.7 of the reference values or better depending on the response of the survey meter. A similar result was obtained when a correction was determined with a prototype reference instrument for Hp(10) after adjustment of its response. Commercially available survey instruments both for photon and neutron H*(10) measurements agreed with the reference instruments in most cases to within 0.5 - 1.5. Those conclusions are derived from results reported within th EC supported EVIDOS contract.
