Radioisotope Experiments for Schools and Colleges describes some radioisotope experiments to delineate atomic events and to provide evidence of the particulate nature of matter. This book is divided into nine chapters, and starts with a discussion on the fundamental of radioisotope, including radioactivity, atomic structure, decay kinetics, radiation-matter interaction, gamma radiation, and isotope production. The subsequent chapters deal with the nuclear radiation measurement methods and the occurrence of natural radioisotopes. These topics are followed by a review of the effect of radiation from external and internal sources on biological tissues. This book also provides demonstration experiments during elementary lectures on radioactivity or, in some cases, by individual pupils and do not involve any accurate measurement. The concluding chapters are devoted to specific experiments using naturally occurring radioisotopes, and sealed and unsealed artificially produced isotopes. This book is of value to physics teachers and students.

This book describes in fascinating detail the variety of experiments sponsored by the U.S. government in which human subjects were exposed to radiation, often without their knowledge or consent. Based on a review of hundreds of thousands of heretofore unavailable or classified documents, this Report tells a gripping story of the intricate relationship between science and the state.Under the thick veil of government secrecy, researchers conducted experiments that ranged from the mundane to such egregious violations as administering radioactive tracers to mentally retarded teenagers, injecting plutonium into hospital patients, and intentionally releasing radiation into the environment. This volume concludes with a discussion of the Committee's key findings and guidelines for changes in institutional review boards, ethics rules and policies, and balancing national security interests with individual rights. Ethicists, public health professionals and those interested in the history of medicine and Cold War history will be intrigued by the findings of this landmark report.

Experiments in Nuclear Science is an introductory-level laboratory manual providing hands-on opportunities for developing insights into the origins and properties of nuclear radiations, their interactions with matter, their detection and measurement, and their applications in the physical and life sciences. Based on experiments successfully perform
