The work presents a new way in which mathematical techniques can be applied to take account of uncertainty in the calibration of instruments which have complex-valued parameters. It presents a clear demonstration of how uncertainty in calibration can be decreased by using an increased number of calibration standards. The meeting was attended by a number of delegates from various European countries and provided a useful forum for the demonstration of this work. Usability Section have won a contract with Armature Ltd., to provide training and consultancy and to supply a Hiser Element Toolkit. The project investigated the reliability aspects of software within instruments which have a high reliability requirement, such as those used in a nuclear power plant.
High reliability is attainable, but can only be assured via an independent assessment.
Technical means of undertaking an assessment are discussed in the project reports, as well as a worked example using Druck's instrument. Brian Wichmann Copernicus Workshop at NPL NPL hosted a four-day Workshop for representatives from high dose calibration Laboratories in Albania, Hungary and Poland. The workshop was part of an EU funded Copernicus project in collaboration with the Risoe National Laboratory, Denmark and included discussion of intercomparison data and proposals for future fellowships at NPL and Risoe. The overall objective is to develop industrial dosimetry calibration laboratories in Central Europe to a level that will allow them to apply for formal accreditation. Measurements for MRC Work is well underway for the Medical Research Council on the measurement of the ionisation chamber response of Kr-81m.
