Childhood Cancer and Nuclear Power Plants

The epidemiological study on childhood cancer in the vicinity of nuclear power plants (KiKK) resulted in the finding that in Germany children under 5 years of age contract cancer, in particular leukaemia, more frequently the nearer they live to a nuclear power plant. Earlier ecological studies already showed an increased risk of children under 5 years of age living within the 5-km-zone around a nuclear power plant site contracting cancer. Since it was designed in a more elaborate way (case-control study) than earlier studies, the KiKK study provides a more reliable database. On the basis of the more exact methodology it could be shown that the childhood cancer incidence rate depends on the distance of the home to a nuclear power plant site and that the increased risk prevails in the entire study region, i. e. also outside the 5-km-zone.

In the study other risk factors were examined, too, which have been known for having a carcinogenic effect or of which this has been assumed. However, no indications could be found that other risk factors can explain why children under 5 years of age living in the vicinity of a nuclear power plant have contracted cancer more frequently than children living farther away. Due to the fact that the risk clearly depends on the distance to the nuclear power plant sites, the study thus provides indications of possible interrelations but it does not provide any proof.

 
Statement by the Federal Office for Radiation Protection on the KiKK Study
 
On behalf of BfS, the German Childhood Cancer Registry in Mainz carried out an epidemiological study about childhood cancer in the vicinity of nuclear power plants, in short KiKK study, which was published in December 2007. Subsequent to the publication, the Federal Minister for the Environment, Nature Conservation and Nuclear Safety charged the Commission on Radiological Protection with the evaluation of the study. more...

Statement on current press reports in regards to the epidemiological study on childhood cancer in the vicinity of nuclear power plants
 
Recently, there have been a number of reports on an advisory opinion about the so-called childhood cancer study (KiKK study), which was provided by experts on behalf of the BfS. In those reports, some facts were presented wrong or ambiguous. more...


Häufigkeit von Krebs bei Kindern in der Umgebung von Kernkraftwerken - atw 53 vom März 2008
 
Die jüngst vorgestellte Epidemiologische Studie zu Kinderkrebs in der Umgebung von Kernkraftwerken (KiKK) hat zum Ergebnis, dass in Deutschland Kinder unter 5 Jahren häufiger an Krebs, insbesondere Leukämie, erkranken, je näher sie an einem Kernkraftwerksstandort wohnen. Das BfS stellt die zentralen Ergebnisse der Studie in einem Artikel der Fachzeitschrift atw dar. Den vollständigen Artikel aus der atw 53 vom März 2008 finden Sie hier. more...


   
Background information on the KiKK study
 
The discussion about increased cancer rates in the vicinity of nuclear power plants has continued since the use of nuclear energy has been considered to be a problematic issue. In 1987 and 1989 British studies reported a statistically significant increase of childhood leukaemia around nuclear facilities in England and Wales. In 1992, an analogously performed ecological study observed a statistically significant increased incidence rate for leukaemias among children below five years of age within the 5-km-zone around the sites. more...


Statement by the external BfS panel of experts on the KiKK study
 
Following an internal discussion of the final report of the KiKK study on December 9 and 10, 2007, the external panel of experts arrives at the following conclusions more...


   
BfS and GCCR jointly support results of the childhood cancer study
 
The main results of the KiKK study are reliable, and are shared by all parties involved in the study. That is the result of a meeting between the contractor of the study, the Federal Office for Radiation Protection (BfS) and the authors of the investigation, the German Childhood Cancer Registry (GCCR). more...


Federal Office for Radiation Protection demands an objective discussion of the KiKK study findings
 
The Federal Office for Radiation Protection demands an objective discussion of the KiKK study findings. The BfS declares that the study is not suitable for ideological arguments and that the findings must be discussed in an open and non-judgemental way. In particular comments made by Katharina Reiche, Deputy parliamentary group leader of the Christian Democratic Union/Christian Social Union (CDU/CSU) parliamentary group, are not suited to a matter-of-fact examination of the finding, demanded by herself. more...


   
Risk of childhood cancer in the vicinity of nuclear power plants: President of the Federal Office for Radiation Protection König presents the findings
 
The risk for children under five years of age to contract leukaemia increases, the closer they live to a nuclear power plant. These are the findings from a study carried out by the German Childhood Cancer Registry in Mainz, lead by Professor Maria Blettner on behalf of the Federal Office for Radiation Protection (BfS). BfS President Wolfram König said: „The study’s findings are sound. So far, no examination has shown any flaws or mistakes in the study design or in the way data has been gained and analysed, which could explain the effect observed." more...


Risk of childhood cancer in the vicinity of nuclear power plants: For the first time, a new study carried out on behalf of the Federal Office for Radiation Protection produces reliable findings
 
The risk of children contracting leukaemia increases with the vicinity of the child’s home to a nuclear power plant. This is the result of a study carried out by the German Childhood Cancer Registry in Mainz on behalf of the Federal Office for Radiation Protection (BfS). It was found that during the study period (1980 – 2003) 37 children, who lived within a 5-km radius of a nuclear power plant contracted leukaemia. The statistical average would have been 17 cases. more...
