| Zusammenfassung | The uncertainties associated with external dosimetry measurements at workplaces depend on the type of dosemeter used together with its performance characteristics and the information available on the measurement conditions. Performance characteristics were determined in the course of a type test and information about the measurement conditions can either be general, e.g. “research”, “medicine”, or specific, e.g. “X-ray testing equipment for aluminium wheel rims”. This paper explains an analytical approach to determine the measurement uncertainty. It is based on the Draft IEC Technical Report IEC 62461 "Radiation protection instrumentation - Determination of uncertainty". Both this paper and the report cannot eliminate the fact that the determination of the uncertainty requires a lager effort than performing the measurement itself. As a counterbalance, the process of determining the uncertainty results not only in a numerical value of the uncertainty, but it also produces the best estimate of the quantity to be measured which may differ from the indication of the instrument. Thus it improves also the result of the measurement. |
