Task 4.1: Evaluation of the concepts for the definitions of radon priority areas

The aim of this task is to review and evaluate the concepts which have already been proposed to define and to estimate RPAs.

In the past a number of different approaches have been brought forward, motivated by the availability of data for the predictor quantities (for various reasons different types of data sets are available in different countries) and by the purpose of RPAs which may also vary.

In course of the EU-BSS process, concrete proposals have been made in some countries, and already implemented in a few cases. These will be reviewed and compared in detail in this Task. Given the possible political and economic consequences of RPAs, stakeholders are keen to promote their interests in the discussions on defining RPAs.
