Description
The system of radiation protection against radon and radon progenies has had a long development, mainly by the ICRP but with significant contributions from other international organizations, such as EC, HERCA, IAEA, UNSCEAR, and WHO.
Within this evolution the role of dose assessment has been important and often subject of discussion and debate, as regards both the scientific aspects and the practical implications.
A typical example is the discussion about the epidemiological and dosimetric approach to the dose assessment, which has often been misunderstood.
Moreover, due to the last (and no more recent) changes of the ICRP dose coefficients (ICRP-137, 2017), with an increase by a factor 2 or 4 compared with previous ones (ICRP-65, 1994), several discussion and initiatives regarding the practical implementation in some workplaces have been carried out and are also on going.
This presentation will try to shortly summarize the above mentioned evolution and to mention the main present issues. Finally some personal comments will be reported.
