This book focuses on the impacts of anthropogenic radiation on wildlife and ecosystems and provides an in-depth look at the approaches and available tools we can use to gain information about biological effects of radiation in the environment.The nuclear accidents in Chornobyl in 1986 and Fukushima in 2011 focussed the attention of the world on the vulnerability of ecosystems to radiation. In Chornobyl, there still remains an exclusion zone where levels are considered to be too high for people and impacts on terrestrial and aquatic ecosystems can still be measured 35 years later. In the area impacted by the Fukushima disaster, intense remediation is still under way at tremendous cost and causing widespread disruption to the environment. That accident impacted the terrestrial and marine ecosystems. In both accidents it became obvious that a radiation protection framework focussing on protection of “humans” (a single species) and using evacuation as a key strategy, was not sufficient to protect the natural environment. The complexity of ecosystems makes developing a protection framework very challenging but in order to even start the process it is vital to gather information about likely impacts of low dose exposures on wildlife and to develop monitoring tools to measure changes over time. This book contains reviews and original research aimed at filling our knowledge gaps about these important areas.Environmental Radiobiology will be a key resource for academics, researchers, and advanced students of Radiobiology, Radioecology, Biology, Ecology, Biomedicine and Research Methods. The chapters included in this book were originally published as a special issue of International Journal of Radiation Biology.

This book contains discussions and deliberations by international experts concerned with the biological effects of low dose exposure to radiation. Everyone knows high doses are harmful but there is huge controversary about low dose effects. Our contributors range from those concerned about long term transgenerational effects of low dose exposure on humans and on the environment, to those who think low doses are beneficial and drive evolution. Novel content in the book refers to efforts to develop new ways of looking at impacts on ecosystems. Human radiation protection is concerned with protecting against adverse effects such as human cancers but in the ecosystem, the approach needs to be holistic – recognising the interdependence of all life on earth. To do this contributors to the book discussed the importance of Earth System Science approaches - moving away from the reductionist approaches to ecosystems currently in vogue. A key feature of the book is the interdisciplinary nature of the participants whose expertise ranges from ecology to genomics and covers physics, chemistry biology, environmental science, bioinformatics, social science and medicine. The book will be of value to those concerned with radiation protection as well as students of environmental science interested in system science approaches to complex environmental and medical issues.

This book is dedicated to the great scientist and outstanding individual Nikolay Wladimirovich Timofeeff-Ressovsky. The book brings together a number of brief stories/essays about Timofeeff-Ressovsky including “Stories told by himself”, and scientific chapters addressing his major research areas: genetics, radiobiology, radiation ecology and epidemiology, and evolution. Timofeeff-Ressovsky contributed to several fields of biology and established new directions of scientific research. He often repeated the phrase, which would later become famous: “Science should not be approached with the ferocity of wild animals”. In keeping with that philosophy, the issues discussed here are still open. Each scientific part starts with a current review; the chapters present leading scientific schools and views. The main theme discussed in the genetics part is mutation variability in the context of linear (replication, transcription, translation) and conformational template processes, and its dependence on phylogenetic group. In turn, the radiobiology chapters focus on the reorganization of DNA, cell, and population variability under low-dose irradiation, sparking indirect processes and adaptive response. The radiation ecology and epidemiology parts present data on the consequences of nuclear plants and related accidents for ecological systems and human beings. Here some approaches to estimating radiation risks are also offered. Evolution laws are demonstrated in the genomic universe, plant-microbe symbiosis, stabilizing and destabilizing (directional) selection. The last essay demonstrates the principles of organization operating in local animal populations, which are approached as social organisms of complex systemic nature.The chapter 'Radiation-Induced Aging and Genetic Instability of Mesenchymal Stem Cells: An Issue for Late Health Effects?' is available open access under a CC BY 4.0 license.

This volume – like the NATO Advanced Research Workshop on which it is based –  addresses the fundamental science that contributes to our understanding of the potential risks from ecological terrorism,  i.e. dirty bombs, atomic explosions, intentional release of radionuclides into water or air. Both effects on human health (DNA and systemic effects) and on ecosystems are detailed, with particular focus on environmentally relevant low-dose ranges. The state-of-the-art contributions to the book are authored by leading experts; they tackle the relevant questions from the perspectives of radiation genetics, radiobiology, radioecology, radiation epidemiology and risk assessment.
