**Preface to "Research on Cosmic Rays and Their Impact on Human Activities"**

Radiation that comes from outside of the Earth continuously interacts with us, even if we do not even notice it. More often than we think, its presence can affect many aspects of human activities. Some of the latest studies on cosmic rays, both those that are low and high energy, are described in this book, providing a snapshot of the latest research in the scientific field and beyond.
