ICRU Committee on Radon Measurements and Reporting of Radon Exposures

09.07.2014

The nine-strong international working group dealing with the elaboration of an ICRU Report on radon measurements held its last common work meeting in Dublin. This report is going to provide worldwide harmonized quality standards for radon measurements (Rn-222 and Rn-220, and their respective progenies) as well as for the handling of exposure determinations and a proposal for a harmonized dosimetry system taking the latest findings from ICRP 115 into account. The report is expected to be published in 2014.

This ICRU Committee was founded in 2011 and is of particular importance, especially for the Europeans: with the European "COUNCIL DIRECTIVE laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation" (EU BSS), radon measurement is becoming a legal task for the first time and the ICRU report will thus become a metrological basis for the transposition of this directive into national law. In this working group, interests of a metrological nature are represented by the team responsible for radon measurement at PTB.
