The book "Methods for determining radioactive substances in the air" by A. Vorobyova is a unique and in-depth study devoted to one of the most pressing topics of our time - radiation safety and ecology. In the face of global climate change and the growing threats posed by radiation, this work is becoming especially important for environmental, health and safety professionals. Vorobyov, known for his scientific works and research in the field of radiation physics, offers the reader not only theoretical analysis, but also practical methods that can be used to monitor and assess the level of radioactive substances in the atmosphere. The book covers a wide range of topics: from the basics of radiation physics to modern technologies and equipment used to measure the radiation background. The author shares his knowledge about various methods, such as spectrometry, radiometry and others, which allow to accurately and effectively determine the presence of radioactive isotopes in the air. This book will be of interest not only to professional ecologists and radiologists, but also to students studying natural sciences, as well as to anyone interested in environmental safety issues. It will be an indispensable tool for those who work in the field of health care, as well as for those who want to understand more deeply how radiation affects our lives and the environment. Readers interested in the topics of ecology, radiation safety and health will find in this book a lot of useful information and practical recommendations. The topics covered in the book go beyond the purely scientific aspects. Vorobyov raises important questions about the effects of radioactive substances on human health and the ecosystem as a whole. It explores how different sources of radiation, both natural and anthropogenic, can have an impact on the environment and public health. The author also discusses modern approaches to minimizing risks and improving monitoring methods, which makes the book relevant in light of the current challenges facing humanity. Vorobyov's style is distinguished by clarity and accessibility, which makes complex scientific concepts understandable to a wide audience. His previous works, such as Environmental Aspects of Radiation Safety and Fundamentals of Radiation Physics, have already established themselves as valuable sources of information for researchers and students. In this book, he continues to develop his ideas, offering readers not only theoretical knowledge but also practical skills that can be applied in real-world settings. The book "Methods for determining radioactive substances in the air" is not just a textbook, but an important contribution to the understanding of radiation processes and their impact on the world. It encourages the reader to think about how important it is to monitor the state of the environment and take action to protect human health and the ecosystem. If you are looking for literature that combines scientific rigor and practical applicability, this book will be a real find for you. Thus, “Methods for Determining Radioactive Substances in the Air” is not just a book, but a whole world of knowledge that will help you better understand the complex processes taking place in our atmosphere, and equip you with the necessary tools to work in this important area. Do not miss the opportunity to immerse yourself in the fascinating and meaningful world of radiation safety with A. Sparrow!
