Gefährdung der Bevölkerung der Schweiz durch Kernkraftwerke: Eine Analyse

(Deutsch weiter unten)

Things have been a bit silent around here for the last days. That’s because I have been busy with a private project of mine: doing a spatial analysis of the exposure of the Swiss population to the dangers of nuclear power plants and writing a report about it.

The processing was done with federal census data and locations of nuclear power plants which I derived myself. I have written up the results in a report in German, so as to suit the intended audience (however, the diagrams in the report should be quite intelligible even if you don’t speak the language). For the same reason I’ll switch to German now.

Über die letzten Wochen habe ich ein privates Projekt verfolgt: Eine Analyse der Gefährdung der Schweizer Bevölkerung durch Schweizer Atomkraftwerke (AKW) und Atomkraftwerke im benachbarten Ausland. Die Leitfrage der Analyse ist:

Welche AKW setzen wieviele Menschen in ihrem Umland einer Gefährdung aus?

Untersucht wurden acht AKW in der und um die Schweiz. Die Analyse kann hier heruntergeladen werden:

"Gefährdung der Bevölkerung der Schweiz durch Kernkraftwerke - Eine Analyse" im PDF-Format: Rechtsklick zum Herunterladen.

Es folgen einige zentrale Abbildungen aus der Analyse.

Untersuchte AKW in der und um die Schweiz

Die Analyse verwendet Daten der eidgenössischen Volkszählung 2000 und die Standorte der AKW. Das Resultat der Analyse sind Diagramme and Statistiken über die Verteilung der Schweizer Bevölkerung um AKW in Abhängigkeit von der Distanz.

Bevölkerungsdichte um AKW

Für jedes AKW kann die Anzahl der von einem Reaktorunfall innerhalb einer gewissen Distanz betroffenen Menschen ermittelt werden. Die Resultate können sie dem Dokument entnehmen, das Sie weiter oben herunterladen können.

Ich hoffe, dass meine Analyse als eine objektive Grundlage im aktuellen energiepolitischen Diskurs dienen kann.

Für Auskünfte zur Analyse, den Bezug des von mir erstellten Quellcode oder der rohen Resultatdaten (aus rechtlichen Gründen nicht aller Eingabedaten), schreiben Sie mir am besten ein Mail.

    Impressive and Important. That’s how I’d classify you excellent piece of work here. Now I’d like to know how the civil protection rates the chances of successfully evacuating (and supplying afterwards for extended periods of time) such large numbers of people…

      Thank you for your comment, Frank.
      I am asking myself the same question regarding civil protection and other authorities. This question is interesting especially before the background of the discussion regarding asylum seekers, where the arrival of several thousand people can apparently already confront authorities with considerable problems regarding provision of accommodation. Let alone the questions of supplying such large numbers of people, as you justly mention in your comment. Much to worry about…

  2. The dominant wind directions in the Swiss midlands are from NEE or W. If you account for it, in reality even more people will be affected by a nuclear worst case scenario.

      Thanks for commenting, Stephan. I realise that of course wind direction will affect the spread of radioactivity. However, despite prevailing wind directions it can’t be known for sure, what meteorological conditions would be in place, once – god forbid – an accident happens. Because of this and for the sake of keeping the analysis, graphics and interpretation of results as simple as possible I opted for an approach which assumes circular, direction-independent spread, also disregarding other potential confounding factors such as topography.

    […] Gefährdung der Bevölkerung der Schweiz durch Kernkraftwerke: Eine Analyse, a post that is dear to me and for which I would wish for even more visitors than it already attracts. There may be more once the Swiss people will maybe vote on the future of nuclear energy. Like the Twitter network, this is one of my spare-time projects and it has also gained quite some popularity outside my usual circles. It is linked to from for example and the analysis which it offers for viewing is cited in Rudolf Rechsteiner’s (former Swiss MP) book “100% erneuerbar” (100% renewable) due to be published in March 2012.
