Paperback. Condición: New. Print on Demand. This book explores the radioactivity of Icelandic hot springs following an expedition in 1906. The author sought to determine the extent to which terrestrial heat influences the Earth's temperature, and what connection, if any, exists between radioactive substances and the Earth's heat. The author examines theories regarding the formation of sulphur in Iceland, explores the unique features of Icelandic springs, and details the devices and methods used to gauge radioactive emanations, a field in its infancy at the time of the expedition. The author's findings, including a previously undocumented phenomenon of steam exhalation, provide valuable insights into the relationship between radioactive substances and terrestrial heat. Detailing the author's experiences and observations, this book offers a fascinating glimpse into early 20th-century scientific exploration, sheds light on the little-known world of Icelandic hot springs, and provides a valuable historical benchmark for future studies in radioactivity and geology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
