Radioactivity

Michael Wiescher is the Freimann Professor of Physics at the University of Notre Dame. He received his Ph.D. at the University of Münster, Germany in 1980. After several years as postdoc and lecturer at Ohio State University, the University of Mainz, Germany, and Caltech, he accepted in 1986 a faculty position at the University of Notre Dame, where he developed a program in nuclear astrophysics using stable and radioactive beams. Dr. Wiescher’s research interests are in low-energy nuclear physics, with focus on nuclear astrophysics and nuclear applications. His research is being pursued mainly at the Notre Dame Nuclear Science Laboratory and at several other national and international research institutions. Between 2003 and 2015, Wiescher served as director of the Joint Institute for Nuclear Astrophysics of the University of Chicago, Michigan State University, and Notre Dame. For the following decade he was director of the Institute for Structure and Nuclear Astrophysics at Notre Dame. He has published approximately 500 scientific and review papers and has served on the organizing and advisory committees of more than 100 national and international workshops and conferences. Dr. Wiescher is a Fellow of the American Physical Society and the American Association of the Advancement of Science. He is also an elected member of the Academia Europaea. In 2003, he was awarded the Hans Bethe Prize in Nuclear Physics and Astrophysics of the American Physical Society, and in 2018 he received the Laboratory Astrophysics Award of the American Astronomical Society. In 2021, Wiescher received the Wolfson fellowship of the British Royal Society and in 2023, he was selected as EMMI visiting professor at the Helmholtzzentrum für Schwerionenforschung in Germany.

Radioactivity is a natural phenomenon which after its discovery more than 100 years ago had a quite exciting, but also controversial history. On one hand, the exploration of its origin opened doors to a deeper understanding of fundamental processes in nature as well as to the structure of matter in the quantum world and its interaction. On the other hand, radioactivity was soon recognized as a powerful tool in applied sciences and in medical applications, but also as a phenomenon with potentially deadly effects.Michael Wiescher takes the reader on an exciting journey into the science and diverse applications of radioactivity. Following a quite comprehensible synapsis of some basic science underlying the different forms of radioactivity, the reader is taken to the stars and other cosmic events, is confronted with nuclear power production and its risk, but also to the role of radioactivity in environmental studies, the fascinating possibilities it offers for studies of art and cultural heritage. The reader can enjoy a thorough discussion about the many applications of radioactivity in medical treatments and diagnosis, here carefully confronted with the harm it can have to living tissues, and in industrial fabrication and quality assurance. Not the least, the book has a close look on radioactivity in connection with nuclear weapons.The book is the outcome of courses which Professor Wiescher has given at Notre Dame University aiming at physics majors but also at students with a general interest in science. The book benefits tremendously from Michael Wiescher's eminent expertise on the subject being a world leading experimental nuclear physicists and an exceptional communicator and teacher. The book can be warmly recommended to researchers, students and scientifically interested readers. I am sure that they will benefit from the book as much as I did. - Karlheinz Langanke, GSI Helmholtz Centre for Heavy Ion Research, March 2025The fear of radioactivity has had profound impacts on the geopolitics of our planet. This book explains in simple language that radioactivity is in fact a very natural phenomenon. Radioactivity helps our planet maintain its atmosphere, heats the earth, and can provide a carbon emission free source of energy. The outlook of the book in two volumes is refreshing and should be read by everyone interested in the future of our planet. Energy is a necessity for growth and innovation; however, the production of that energy needs to be something that does not destroy the planet. Radioactivity Volume I: A Natural phenomenon explains the fundamentals of radioactivity and its role in the chemistry and biology of life. The origin of life, the origin of the radioactive elements that make up our universe, and the radioactive universe itself in everyday terms accessible to the public. In Volume II: Anthropogenic sources, Wiescher describes the radioactivity created by humanity in burning fossil fuels, in testing nuclear weapons, in the creation of energy, and its numerous uses in society from medicine to industry and the study of art and archeology. Today, nuclear medicine is a thriving subdivision of the medical field with the use of radioactive isotopes that both diagnose and simultaneously treat tumors. The history of humanity is now also explored with the use of radioactivity that can reveal composition, provenance, and age of archeological objects or even modern pieces of art. The second volume addresses and encourages a second look at nuclear energy through the lenses of a better understanding of radioactivity. Ani Aprahamian, Professor of Chemistry & BioChemistry at University of Notre Dame, March 2025Both books Radioactivity I and II, written by one of the world’s leading and most accomplished nuclear astrophysicists, Michael Wiescher, are great examples for a successful introduction and deepening of the naturally occurring phenomenon of radioactivity.The author illuminates the many different facets of this fascinating subject – from natural occurrence, its sources and effects on our everyday life, to the anthropogenically created sources and their technological impact and applications. He thoroughly describes, also for beginners, the basic science, and does not leave out difficult topics like nuclear weapons and their consequences for mankind.Both books are an incredible resource: they are rich in content but are also supplemented with extensive references. As such, for me, they serve as an excellent guide for lecture preparation as well as an accompanying extension for students at all levels seeking a deeper and wider understanding of the topic Radioactivity.Personally, I highly recommend both volumes – everyone interested, and every expert should have both books on their bookshelf.- Dr. Christoph Langer, Professor for Applied Nuclear Physics at University in Aachen, March 2025
