The subject of the book is of general interest. Experience of propagation and use of Russian version of the book shows, that the problem attracts the attention not only from professionals, but also of general public. But the non-specialists could face the difficulties in comprehending the whole book because of the complex terminology used for scientific descriptions. In his book the author tried his best to smooth this problem and to use more understandable terms, and to clear up the complex ones right on the spot. Besides all the necessary data in the nuclear physics and in biology are presented in the book. A reader does not need to search for this information in libraries and on the Internet. Thus, the book is can be quite understandable to a wide range of curious readers who are interested in the question of the true sources of danger trapping the person in the everyday life. For the user (why should he/she buy the book? A more scientific description of the book for the actual user/scientist/expert) The book is intended for students, graduate students and professionals in the fields of physics, chemistry, biology, ecology, and a range of interdisciplinary sciences.

It can be used by practitioners as a reference to find sources of more detailed information on special issues of radiation and chemical safety. There are more than three hundred references in the book. Those interested in the problems of life safety could also find here a lot of useful information For the first time in this book the problems of radiation and chemical safety are considered together on a common biophysical basis. Hazards caused by ionizing radiation and chemicals, could and should be considered together. There is a lot in common in the mechanisms of the effects of these damaging factors. Also a lot in common is in research methodology and methods of data processing. Finally, in many cases there is the same final effect, and that is cancer. Special attention has beeen paid to low doses of both radiation and chemicals.

Low doses of radiation and small doses of chemicals are continuously active, regardless of our desires and lifestyle and they could influence on the entire population. The analysis of two main sources of hazard for the lives of ordinary humans is to be for the first time shown in one book and on a common basis. All necessary knowledge in nuclear physics, biology, and in the methods of processing the results of experiments has been delivered all in one book. The reader is mostly not meant to search for this information in libraries, Internet and so on.
