Abstract
The International Commission on Radiation Units and Measurements (ICRU) has, jointly with the International Commission on Radiological Protection (ICRP), recently proposed a set of new operational quantities for radiation protection in ICRU report 95. ICRU/ICRP supplied conversion coefficients for mono-energetic betas but not for beta reference radiation qualities defined by the International Organization for Standardization (ISO) in ISO 6980. Therefore, in this work, conversion coefficients from absorbed dose to tissue at a depth of 0.07 mm in a slab phantom to the newly proposed operational quantities are determined for beta reference radiation qualities. Finally, the impact of the newly proposed quantities on primary and calibration laboratories and on users and manufacturers of dosemeters is investigated, the latter by having a close look at the expected change of the response of dosemeters.
