radiation epidemiology cohort 3-generation exposure study This three-generation study in Kazakhstan follows individuals and their descendants living near the Semipalatinsk Nuclear Test Site, investigating whether radiation effects are transmitted across generations through epigenetic or genomic mechanisms. It provides a unique multi-generational dataset from a population exposed to nuclear weapons testing fallout, supporting research on transgenerational radiation effects and heritable genomic instability. Access is after agreement with the Institute. Located at Scientific Research Institute of Radiation Medicine and Ecology. AIR², Issue 5, March 2016 Paul Schofield
