Intercomparison of Radiation Protection Instruments Based on Microdosimetric Principles

摘要

Dosemeters based on low-pressure tissue-equivalent proportional counters were developed for the application in radiation protection area monitoring by several groups in Europe. Five different prototypes have been intercompared in a /sup 60/Co photon field, in monoenergetic neutron fields with various energies between 73 keV and 5 MeV and in three neutron fields at a /sup 252/Cf source moderated by a D/sub 2/O sphere. This report describes the radiation fields, the measuring devices and first results of the intercomparison. Additional measurements with a system used in microdosimetry and with a conventional dose equivalent rate meter for neutrons (Rem Counter) were also described. (ERA citation 12:029155)
