Title: Chernobyl fallout and perinatal mortality in England and Wales

Keywords: Chernobyl fallout, perinatal mortality, England, Wales

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.

Title: The use of weather radar in assessing deposition of radioactivity from chernobyl across England and Wales

Abstract: Deposition of radionuclides from the Chernobyl accident depended critically on patterns of precipitation intercepting the material. This paper describes the use of the RAINPATCH model to calculate wet deposition of 137Cs over England and Wales. This puff-based model makes direct use of precipitation data measured by weather radar to determine the scavenging of airborne material. The detailed spatial and temporal resolution of when and where material was scavenged provides good agreement with measurements. Since all the data used could potentially have been available at the time, such methods could usefully be applied in real time in the event of any future accident releasing such radionuclides.
