Scope
What are the radon concentrations in European residences, now and in the future?
Definition
Initial data is compiled from National Summary Reports, EnVIE project [1] and UNSCEAR 2000 [2].
Future concentrations are constructed from current concentration data and predicted residence air exchange rates, by using <math>c_n = \frac{a_0+k}{a_n+k}c_0</math>, where c is concentration, a is air exchange rate and k is decay rate (radioactive decay of Rn222).
Original Data
Country | Number of dwellings sampled | Period and approx duration of measurement (situation in end 2008) | Arithmetic mean (Bq/m3) | Population 'dose' (M#*Bq/m3) | Geometric mean (Bq/m3) | Geometric SD (Bq/m3) | Per cent >200 Bq/m3 | Per cent >400 Bq/m3 | Max obs (Bq/m3) |

Notes.
- Changes since EnVIE [1]: Bulgaria arithmetic mean added. Data existing in UNSCEAR but not in EnVIE; data was added here: Geometric mean for Luxembourg, Norway, Poland, Slovenia (also GSD), Switzerland.
- The UNSCEAR data table is on a previous version of this page.
- Original Excel file: N:\ILMA\_Projects\ENVIE\WP-2
Causality

Unit
Bq/m3
Formula
- Initial concentration data is downloaded from an earlier run, for which the details can be found in the earlier page version under "Formula".
