* Laboratory can implement minor modifications of the method as necessary (e.g. adaptation to the new version). Detailes on the actual state of the scope is maintained by the laboratory.
** In April 2020 complete revision of the procedure was performed. Updates due to the new revision of the IEC 62387 standard (ed. 2.0, January 2020) were implemented and a complete revision of the uncertainty budget was performed. Besides improvements in the response of the finger dosemeters at different energies were introduced.
