Written by chemists for chemists, this is a comprehensive guide to the important radionuclides as well as techniques for their separation and analysis. It introduces readers to the important laboratory techniques and methodologies in the field, providing practical instructions on how to handle nuclear waste and radioactivity in the environment.
Nuclear energy is the one energy source that could meet the world's growing energy needs and provide a smooth transition from fossil fuels to renewable energy in the coming decades and centuries. It is becoming abundantly clear that an increase in nuclear energy capacity will, and probably must, take place. However, nuclear energy and the use of radionuclides for civilian and military purposes lead to extremely long-lived waste that is costly and highly problematic to deal with. Therefore, it is critically important ot understand the environmental implications of radionuclides for ecosystems and human health if nuclear energy is to be used to avoid the impending global energy crisis. The pre...
Radioactive particles have been released to the environment from a number of sources, including nuclear weapon tests, nuclear accidents and discharges from nuclear installations. Particle characteristics influence the mobility, biological uptake and effects of radionuclides, hence information on these characteristics is essential for assessing environmental impact and risks. This publication presents a series of papers covering sources and source term characterisation, methodologies for characterizing particles, and the impact of particles on the behaviour of radioactive particles in the environment. Sources covered include the Chernobyl accident, nuclear weapons accidents at Thule and Palomares accident, the discharges from Dounreay and Krashnoyarsk, and depleted uranium in Kosovo and Kuwait. The overall aim is that an increased understanding of particle characteristics and behavior will help to reduce some of the uncertainties in environmental impact and risk assessment for particle contaminated areas.
It is extremely difficult to seek new paths in the twilight of our former idols, ideals and visions of a happy and successful life. The authors of the book invite the reader to embark on this journey in a free-spirited manner and to look at the challenges posed by the new climate regime from different perspectives. Whether one accepts the concept of the Anthropocene as a starting point, or rather as an opportunity for constructive criticism, readers will be fully engaged by thinking through historical-philosophical, scientific, political, social, as well as educational problems.
IAU Symposium No. 167 brought together researchers who use CCDs and arrays, designers and manufacturers of CCDs and Array Mosaics and those who write the software to control these devices and to reduce the large amounts of data contained in each frame. At the meeting such topics as plans for applying the new technology to the new large telescopes that have been built recently and those planned in the near future, new developments in infrared arrays, advances and concerns with the use of CCDs in photometry and spectroscopy and the creation of large mosaics in photometry and spectroscopy and the creation of large mosaics of chips which allow larger areas of the sky to be covered in a single fr...
The present treatise is the final milestone in the radioecology programme, RAD, carried out from 1990 to 1993 under the Nordic Committee for Nuclear Safety Research, NKS. The book, one of the few in its field to have achieved international publication, is centred on the contamination of Nordic environments with radionuclides from the Chernobyl accident. It contains 30 contributions mainly describing the flow of radiocaesium through aquatic, agricultural, forest, and alpine ecosystems, as well as quality assurance and doses to man. A series of original papers on various aspects of Nordic post-Chernobyl radioecology by leading Nordic scientists is also included, along with terms & units definitions, indexes, and an executive summary.The volume will be invaluable to all scientists and professionals in radioecology, radiation protection, trace element cycling and environmental contamination. It will also be relevant to general evironmental management/human contamination/civil defence officials.
This book provides a study of radiation and environmental safety in north-west Russia. International experts from several related fields offer a thorough understanding of the present status. They suggest how to develop the use of overall risk assessments and environmental impact assessments to ensure a sound use of resources when carrying out the tremendous work that must be carried out to clean up the cold war legacy.
