The Effects of Low Dose Radiation New aspects of radiobiological research prompted by the Chernobyl nuclear disaster

By Elena Burlakova, Valeria Naiditch Copyright 2004

    The papers collected in this book show the results of investigations performed by Russian scientists in the field of low dose irradiation action. It is confirmed that low doses do have effects on the human organism and the environment and that the most serious consequences are observed in the far post-irradiation period. This branch of radiobiology, which developed after the Chernobyl accident and studied its consequences, is discussed in detail. The main part of reviews and articles is devoted to the aspects of low dose effects on the human and animal genome and far post-irradiation consequences. New details of mechanisms of low dose action are shown and methods of their determination are discussed. Furthermore, the adaptive response of organisms and the low dose effects on the immune system are demonstrated. Also, the difference between protection mechanisms against low dose irradiation and against high dose irradiation is shown and proved.

    'This book is a collection of twenty-one scientific research papers on the biological effects of low dose radiation based on research data collected in the twenty years following the Chernobyl nuclear disaster…The data in this book would be a valuable tool for someone doing advanced research on the subject of low dose radiation exposure…' Daphne Wetmore, The Canadian Journal of Medical Radiation Technology, 2005.
