概要：先行研究では、チェルノブイリ放射性降下物が西ドイツおよび米国における周産期死亡率の増加の原因になっている可能性が指摘されてきた。イングランドおよびウェールズにおける汚染は明らかに地域的に多様であるため、地理学的研究によってこの問題をさらに追究することが可能となった。イングランドおよびウェールズにおける最も高いチェルノブイリ放射線量は、放射性雲が通過する間に大雨があったカンブリア、クルーイドとグウィネズにおいてみとめられた。しかし、これらの地域における周産期死亡率は、チェルノブイリ事故後の年における国の平均と比べて上がったわけではなかった。この否定的結果は地元のミルクの放射能汚染レベルに応じてグループ分けされた14郡のより広範な調査によって確認された。本研究では、チェルノブイリからの放射能がイングランドとウェールズにおける周産期死亡率の上昇を引き起こしたという証拠は提供されなかった。

Title: Perinatal mortality in Bavaria, Germany, after the Chernobyl reactor accident

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.
