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 neutron irradiation of uranium led to the discovery of nuclear fission in 1938 and then to the first transuranium element, neptunium (atomic number 93), in 1940. Plutonium (94) quickly followed and the next nine elements completed the actinide series by 1961. Investigation of the chemical properties of the actinides was followed more recently by chemical studies of the first three transactinides — rutherfordium (104), hahnium (105), and seaborgium (106). Recent discoveries have extended the known elements to 112./a

DOWNLOAD EBOOK →Nearly three years have passed since the publication of the original Russian edition, in which time there have appeared various papers on recent research on the transuranium elements, of which the most notable concern the production of element 105 at Dubna and Berkeley. There has also been much fresh information on elements 104 (kurchatovium) and 103 (lawrencium). Our knowledge of shell effects in the fission barrier has been extended. Hopes of finding relatively stable superheavy elements have stimulated searches for such elements in nature as well as rapid development in heavy ion acceleration. We may see some very considerable discoveries in the next few years. The new results vary in reliability, and so it is not surprising that some papers on the properties of the heaviest elements have given rise to vigorous debates, whose value lies in the way they ad vance the subject. We have not attempted to give an exhaustive survey of recent papers and have merely added brief sections to reflect what we con sider to be the most important points from these. So far, the United states and the USSR have made the most considerable contributions to the synthesis, study, and use of the transuranium elements, so it is especially welcome to us that this book, first published in our country, should now appear in the USA in an English translation.

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.
