Conversion coefficients from absorbed dose to tissue to the newly proposed ICRU/ICRP operational quantities for radiation protection for beta reference radiation qualities

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.
