Abstract

AIMS: The Windscale (UK) fire of 1957 carried radioactive fallout according to the then prevailing wind patterns, in a North-Easterly direction across the Nordic countries, toward Norway. The male:female ratio at birth (M/F) is known to be increased after parental exposure to ionising radiation due to foetal losses that affect female more than male pregnancies. This study was carried out in order to ascertain whether the Windscale fire had any effects on M/F and birth rates in the United Kingdom and Scandinavia.

METHODS: Annual live births by gender were obtained from a World Health Organization dataset. The null hypothesis was that there were no significant changes in M/F or in births in temporal association with the 1957 Windscale event in abovementioned countries.

RESULTS: There were no significant effects on the UK and most of Scandinavia but there was a significant rise in M/F for Norway and Finland with an aggregate deficit of around 4000 births in each country.

CONCLUSIONS: A recent study suggests that the plume from the reactor extended further east than previously believed. This study confirms that contamination from the Windscale fire had a negligible impact on the UK (as measured by birth effects) but had a significant impact on births in Norway and Sweden.
