It has long been known that ionizing radiation causes genetic mutations and that nuclear bomb testing, nuclear accidents, and the regular and incidental emissions of nuclear facilities enhance environmental radioactivity. For this reason, the carcinogenic and genetic impact of ionizing radiation has been an escalating issue for environmental health and(More)
 Risk assessment – qualification and quantification of risks  The focus in this presentation is on ionizing radiation (IR) and possible radiation induced changes in the human sex odds at birth (SO) near Nuclear Facilities (NF)  Traditionally, the SR is the pertinent term for the number of newborn boys divided by the number of newborn girls SR =(More)
BACKGROUND The ratio of male to female offspring at birth may be a simple and non-invasive way to monitor the reproductive health of a population. Except in societies where selective abortion skews the sex ratio, approximately 105 boys are born for every 100 girls. Generally, the human sex ratio at birth is remarkably constant in large populations. After(More)
The aim of our research is to investigate sex odds trends in the vicinity of nuclear facilities and chemical plants in Germany. We collected human sex odds data from the nineteen fiftieth till 2010. To assess time trends in the occurrence of boys among all live births, and to investigate whether there have been significant changes in the trend functions(More)
INTRODUCTION The male:female ratio at birth (male births divided by total live births - M/T) has been shown to increase in response to ionizing radiation due to gender-biased fetal loss, with excess female loss. M/T rose sharply in 1987 in central-eastern European countries following the Chernobyl accident in 1986. This study analyses M/T and births for the(More)
The possible detrimental genetic impact on humans living in the vicinity of nuclear facilities has been previously studied. We found evidence for an increase in the human secondary sex ratio (sex odds) within distances of up to 35km from nuclear facilities in Germany and Switzerland. Here, we extend our pilot investigations using new comprehensive data from(More)
