Radon measurements in Big Buildings

Developing a standard protocol

Experimental section

The experimental research section is divided in two different groups/topics:

  1. Definition of test conditions and quality control for each building type
  2. A definition of test conditions which reflect the daily usage of the building, including movements of people (like opening and closing doors, elevator usage) is essential for realistic scenario and an estimate of the daily dose of radon radiation. Parameters like the frequency of air exchange due to people’s movement have to be taken into account.

  3. Finding test buildings, defining equipment and test period, running test data analysis.
  4. To find adequate test buildings various databases, containing radon measurements of the past will be evaluated, including a research for the established parameters.

 

Recent measurements:

Mid November Angelika Kunte from AGES in Austria started to measure a three floor school building in Carinthia with 81 dosemeters for about three months, results will be shared within the project.

On monday, december 9, 2016, one hundred dosemeters from Landauer Nordic were distributed at the Swiss National Supercomputing Centre SNSC in Lugano (special thanks to Luca Pampuri RCC, Tiziano Belotti SNSC and Luca Bacchetta SNSC for the support). The building consits of a five floor office section and a three floor machine section with huge areas. This covers already two different building types.

Our colleagues Ingo Fesenbeck and Christian Naber from the Karlsruhe Institute of Technology KIT Germany, placed around 460 detectors in two buildings, one old and one new. Bigger rooms have been stocked with more detectors (about 1 MP/50m2). The measuring period will be around 100 days.

Ulrich Buchner from the Bavarian Environment Agency placed 122 detectors in a 4 storey University building from 1975 containing one basement and three upper floors. Measurement time was from September 2015 to March 2016. Also these data will be integrated in the database.

Boris Dehandschutter (FANC Belgium) presented a school building measured with 30 detecors in place and an office building with 40 detectors. Two more schools and one office building are also in the line and will give results soon.

Jose Gutierrez Villanueva (University of Cantabria, Spain) launched measurements in the building of the Spanish Nuclear Safety Council in Madrid using 50 detectors (one for each room) for three months.
