Abstract: Previous studies have concluded that radioactive fallout from Chernobyl may have caused an increase in perinatal mortality in West Germany and the U.S.A. The existence of marked geographical variations in contamination from Chernobyl in England and Wales provides an opportunity to investigate this question further by means of a geographical study. The highest doses from Chernobyl in England and Wales were in the counties of Cumbria, Clwyd and Gwynedd where there was heavy rainfall during the passage of the radioactive cloud. However, perinatal mortality in these areas did not rise relative to the national average in the year following Chernobyl. This negative finding was confirmed by a wider study of 14 counties grouped in accordance with levels of radioactive contamination of local milk. It is concluded that this study provides no evidence that radiation from Chernobyl caused a rise in perinatal mortality in England and Wales.

Abstract: As has been shown by the authors of a paper recently published in this journal, a deviation from a long-term trend in perinatal mortality within the former Federal Republic of Germany occurred in 1987, i.e. 1 year following the Chernobyl disaster. It is the aim of this study to make a comparison between the areas of the state Bavaria. Germany, with different fallout levels as well as between the observed and expected numbers of perinatal deaths relating to these areas. The expected numbers of perinatal deaths, defined as external standard, were derived from the remainder of the former FRG. Testing an a priori formulated hypothesis revealed no differences in the temporal development of perinatal mortality between the areas with different fallout levels and subsequent exposure. Including May 1986 into the analysis revealed a significant increase during the first 3 months after the accident, which is due to an excess in May alone. Since no elevated radiation risks for the last days in utero are known, the additional Chernobyl radiation exposure is not plausible as a causative agent. Further analyses on stillbirths showed an increase in Southern Bavaria during the first 2 years following the accident. Later on, the rates were comparable to the expected values again.

Title: Perinatal mortality in Germany following the Chernobyl accident

Keywords: perinatal mortality, Germany
Abstract: Perinatal mortality in Germany was investigated with respect to a possible relationship to the nuclear accident in Chernobyl on April 26, 1986. Using annual data of perinatal mortality, a trend analysis based on an appropriately chosen statistical model was performed which showed a significant increase in 1987. In addition, we calculated the cesium concentration in women’s bodies using data of the cesium concentration in milk. We found two peaks of cesium concentration that were associated with the observed two peaks of monthly perinatal mortality data with a delay of 7 months.
