International Workshop on the European Atlas of Natural Radiation

By Uncategorized 3 Comments

The second edition of the International workshop on the European Atlas of Natural Radiation took place in Verbania, Italy from 6th to 9th November 2017. More than 70 participants gathered in this Italian city on the shore of the famous Lake Maggiore. The audience was composed of researchers and authorities with responsibility for radiological protection.  A small number of private companies were among the participants including Radonova Laboratories AB. The European Radon Association was also represented at this meeting.

Description

The workshop included 10 sessions and 60 oral presentations. The sessions dealt with the following topics:

  1. Radon policies
  2. Sources of natural radiation: geochemical, gamma, soil and water
  3. Sources of natural radiation: instruments, buildings
  4. Radon and geology
  5. Radon priority areas: methodology
  6. Radon priority areas: risk, mapping, classification
  7. Relationship between variables: methodology, multivariate
  8. Relationship between variables: multivariate, transport
  9. Indoor radon
  10. Atlas publication

Radon policies, radon as a tracer and radon in water

The workshop opened with Radon policies and during that session speakers from IAEA, EU, WHO, ERA and other on-going research projects, (metroRADON, LIFE-RESPIRE, Ribibui) discussed the current effect of the radon issue on EU legislation and the Basic Safety Standards documents issued by the EU and IAEA. The question of the current state of DCF’s (Dose Conversion Factors) was addressed as well as radon enforcement actions. Speakers representing 11 countries made presentations concerning sources of natural radiation. The first talk of this session showed the current state of the European Radon Map. It followed talks about the use of radon as a tracer, surveys performed in some countries to assess exposure to gamma radiation, fertilisers with radionuclide content and building materials. Also, radon in water was included for the first time in the workshop.

Radon priority areas, geology and eartquakes

The connection between radon and geological activity included the topic of using radon to forecast earthquakes. The new EURATOM BSS requires the need to define radon priority areas in the EU member states. Therefore, a significant number of presentations were devoted to this subject. Germany, Ireland, Austria, Croatia and Spain presented their advances on this important topic that will be very relevant in the upcoming implementation of the EURATOM BSS Directive. The last day included presentations focusing on indoor radon surveys in various countries, especially those in Eastern Europe.

The European Atlas of Natural Radiation

To conclude the workshop, Giorgia Cinelli and Tore Tollefsen (JRC, EU) presented their progress to date with the publication of the European Atlas of Natural Radiation. This is intended to be an encyclopaedia of natural radiation and it is expected to be finalised at the end of 2018.
