Preface

摘要

This English written book was mainly a translation from the books above. I would like to take this opportunity to thank David for all help with the translation.The three books concentrated to a large extent on the basic properties of ionizing radiation. Efforts were made to describe the background radiation as well as the release of radioactivity from reactor accidents and fallout from nuclear explosions in the atmosphere. These subjects were of high interest in the aftermath of the Chernobyl accident. During the later years a large amount of research and interesting new results within radiobiology have emerged. The purpose of the present is book is therefore to include some interesting applications of radiation in medicine as well as some of the exciting mechanisms in radiobiology.
