The book describes the interaction of living matter with photons, neutrons, charged particles, electrons, and ions. The authors, as experts in radiation protection, share their knowledge and years of experience in the study of ionizing radiation and experiments in the fields of dosimetry and radiation shielding, medical physics, as well as the applications of radiation in industry and research. The following pages present the basic (physical) concepts of dosimetry and radiation protection, combined with practical applications that can be used by students, researchers, engineers, and technicians to assess radiation risks and develop protective measures. The authors provide the theoretical background for understanding the interaction of radiation and matter, along with the necessary mathematical tools and useful data tables that allow for the handling of various problems related to radiation protection and radiophysics. Numerous numerical applications are also mentioned, guiding the reader towards a deeper understanding, focusing on the latest technology in the fields of radiation protection and dosimetry.

A valuable resource that covers a plethora of topics, including radiation from accelerators, X-ray facilities, sealed radiation sources, dosimetry, and Monte Carlo simulations in radiation studies. Each chapter is divided into two parts. The first part is aimed at a wider audience and provides many simple examples. The second part, which can be skipped by non-specialists, aims to further explore the topics by introducing the necessary mathematical formalism. The book analyzes all the fundamental concepts of radiation and radioprotection, in order to fully describe the interaction of radiation with various materials and the methods of radiation protection in industry, medical physics, and pure research. Finally, some more specialized applications that have been developed in recent years are examined, such as particularly powerful laser sources and future particle accelerators.
