In the early nineteenth century chemists knew of the existence of ninety-two chemical elements, from Hydrogen to Uranium. For nearly forty years scientists thought they knew the content of our planet and all of its contents. In the late 1930s the world of chemical science began to discover elements beyond Uranium - the 'transuranics'. These new, super-heavy elements are probably not found in nature at all but can be detected, if only for a few fractions of a second, in precisely designed experiments using powerful nuclear tools. On Beyond Uranium: Journey to the End of the Periodic Table is full of exciting new concepts and tells the story of the author's quest to discover elements never before known to man.

This book describes hazards from radon progeny and other alpha-emitters that humans may inhale or ingest from their environment. In their analysis, the authors summarize in one document clinical and epidemiological evidence, the results of animal studies, research on alpha-particle damage at the cellular level, metabolic pathways for internal alpha-emitters, dosimetry and microdosimetry of radionuclides deposited in specific tissues, and the chemical toxicity of some low-specific-activity alpha-emitters. Techniques for estimating the risks to humans posed by radon and other internally deposited alpha-emitters are offered, along with a discussion of formulas, models, methods, and the level of uncertainty inherent in the risk estimates.

The story of superheavy elements - those at the very end of the periodic table - is not well known outside the community of heavy-ion physicists and nuclear chemists. But it is a most interesting story which deserves to be known also to historians, philosophers, and sociologists of science and indeed to the general public. This is what the present work aims at. It tells the story or rather parts of the story, of how physicists and chemists created elements heavier than uranium or searched for them in nature. And it does so with an emphasis on the frequent discovery and naming disputes concerning the synthesis of very heavy elements. Moreover, it calls attention to the criteria which scientists have adopted for what it means to have discovered a new element. In this branch of modern science it may be more appropriate to speak of creation instead of discovery. The work will be of interest to scientists as well as to scholars studying modern science from a meta-perspective.

The hidden history of African uranium and what it means—for a state, an object, an industry, a workplace—to be “nuclear.” Uranium from Africa has long been a major source of fuel for nuclear power and atomic weapons, including the bomb dropped on Hiroshima. In 2003, after the infamous “yellow cake from Niger,” Africa suddenly became notorious as a source of uranium, a component of nuclear weapons. But did that admit Niger, or any of Africa's other uranium-producing countries, to the select society of nuclear states? Does uranium itself count as a nuclear thing? In this book, Gabrielle Hecht lucidly probes the question of what it means for something—a state, an object, an industry, a workplace—to be “nuclear.” Hecht shows that questions about being nuclear—a state that she calls “nuclearity”—lie at the heart of today's global nuclear order and the relationships between “developing nations” (often former colonies) and “nuclear powers” (often former colonizers). Hecht enters African nuclear worlds, focusing on miners and the occupational hazard of radiation exposure. Could a mine be a nuclear workplace if (as in some South African mines) its radiation levels went undetected and unmeasured? With this book, Hecht is the first to put Africa in the nuclear world, and the nuclear world in Africa. By doing so, she remakes our understanding of the nuclear age.

Shortlisted for the 2020 AAAS/Subaru SB&F Prize for Excellence in Science Books Creating an element is no easy feat. It's the equivalent of firing six trillion bullets a second at a needle in a haystack, hoping the bullet and needle somehow fuse together, then catching it in less than a thousandth of a second – after which it's gone forever. Welcome to the world of the superheavy elements: a realm where scientists use giant machines and spend years trying to make a single atom of mysterious artefacts that have never existed on Earth. From the first elements past uranium and their role in the atomic bomb to the latest discoveries stretching our chemical world, Superheavy will reveal the hidden stories lurking at the edges of the periodic table. Why did the US Air Force fly planes into mushroom clouds? Who won the transfermium wars? How did an earthquake help give Japan its first element? And what happened when Superman almost spilled nuclear secrets? In a globe-trotting adventure that stretches from the United States to Russia, Sweden to Australia, Superheavy is your guide to the amazing science filling in the missing pieces of the periodic table. By the end you'll not only marvel at how nuclear science has changed our lives – you'll wonder where it's going to take us in the future.

Uranium, the most atomically unstable natural element on earth, has a unique place in the global geopolitics of resources. It provides energy to millions of people and its isotopes are used to power spacecraft and in nuclear medicine. But it is also at the heart of many of the planet's most deadly threats, including nuclear devastation and radioactive waste. Its mining has caused bitter conflict with indigenous peoples and its testing in nuclear weapons has left a toxic legacy. Yet the nonproliferation regime which aims to phase out nuclear weapons and manage the risks of nuclear energy is at risk of unravelling. In this book, Anthony Burke explores the geopolitical intrigue around uranium and the dilemmas of justice and security to which its development has given rise. The twenty-first century, he cautions, will be a time of reckoning and new reserves of political will must be found to manage the impact of this extraordinary mineral. Only by cooperating to achieve multilateral disarmament and greater international control over nuclear power can we ward off nuclear catastrophe and harness the potential of nuclear energy to help address, rather than create, some of the world's most pressing problems.

An important prerequisite to the long-term use of nuclear energy is information on uranium ore deposits from which uranium can be economically exploited. Hence the basic purpose of this book is to present an overview of uranium geology, data characteristic for uranium deposits, and a synthesis of these data in the form of a typological classification of uranium deposits supported by more detailed descriptions of selected uranium districts and deposits. An additional goal is to provide access for the interested reader to the voluminous literature on uranium geology. Therefore a register of bibliography as global as possible, extending beyond the immediate need for this book, is provided. The volume presented here was not originally designed as a product for its own sake. It evolved as a by-product during decades of active uranium exploration and was compiled thanks to a request by the Springer Publishing Company. Routine research work on identifying characteristic features and recognition criteria of uranium deposits, combined with associated modeling of types of deposits for reapplication in exploration, provided the data bank. The publisher originally asked for a book on uranium deposits structured as a combined text- and reference book. The efforts to condense all the text into a single publication were soon doomed. The material grew out of all feasible proportions for a book of acceptable size and price, a wealth of data on uranium geology and related geosciences having become available during the past decade, too vast for one volume.
