Concentrating on techniques for the detection and measurement of radioactivity, this book offers a guide to selecting the type of counter, type of source sample, duration for which the counting must be made, and the radiation emitted by the isotope for its efficient detection. It introduces a novel concept to explain not only the decay processes but also the selection of counting procedures for detecting and measuring radioactivity. The author builds up the foundation from the nature of the interaction of radiation with matter. He also highlights the differences between an ordinary chemical laboratory and a radiochemical one.

Low-Energy Nuclear Reactions and New Energy is a summary of selected experimental and theoretical research performed over the last 19 years that gives profound and unambiguous evidence for low energy nuclear reaction (LENR), historically known as cold fusion.
In 1989, the subject was announced with great fanfare, to the chagrin of many people in the science community. However, the significant claim of its discoverers, Martin Fleischmann and Stanley Pons, excess heat without harmful neutron emissions or strong gamma radiation, involving electrochemical cells using heavy water and palladium, has held strong.
In recent years, LENR, within the field of condensed matter nuclear science, has begun to attract widespread attention and is regarded as a potential alternative and renewable energy source to confront climate change and energy scarcity. The aim of the research is to collect experimental findings for LENR in order to present reasonable explanations and a conclusive theoretical and practical working model.
The goal of the field is directed toward the fabrication of LENR devices with unique commercial potential demonstrating an alternative energy source that does not produce greenhouse gases, long-lived radiation or strong prompt radiation. The idea of LENR has led to endless discussions about the kinetic impossibility of intense nuclear reactions with high coulomb barrier potential. However, recent theoretical work may soon shed light on this mystery.
Understanding this process is one of the most challenging and perhaps important issues in the scientific world. This book includes previously unpublished studies, new and controversial theories to approach LENR with access to new sources and experimental results. The book offers insight into this controversial subject and will help readers re-evaluate their perspective on LENR as a possible alternative energy source.

Colorimetry is concerned with the measurement of, and discrimination between, colours. These are important topics in a wide range of the physical sciences, life sciences, and computing and engineering. Examples of specific areas where the techniques of colorimetry are used are: manufacturers of paints, textiles, plastics and cosmetics (and quality controllers in these industries), those interested in the effect of light in human environments (for example, in terms of its direct effects on the eye, laser safety and design of eye protection and ergonomics of hospital lighting), psychology, physiology and those involved in the technical aspects of photography. The book presents the physiological background behind how colour is perceived and discusses sources of visible radiation, before going on to describe in detail colorimetric techniques for measuring and discriminating between colours. Applications of these techniques are discussed and relevant mathematical data is provided. The book gives a comprehensive account of the physiological aspects of colour, the development of photometry and colorimetry, and applications of colorimetry in a single volume.

Radioactivity: History, Science, Vital Uses and Ominous Peril, Third Edition provides an introduction to radioactivity, the building blocks of matter, the fundamental forces in nature, and the role of quarks and force carrier particles. This new edition adds material on the dichotomy between the peaceful applications of radioactivity and the threat to the continued existence of human life from the potential use of more powerful and sophisticated nuclear weapons. The book includes a current review of studies on the probability of nuclear war and treaties, nonproliferation and disarmament, along with historical insights into the achievements of over 100 pioneers and Nobel Laureates. Through multiple worked examples, the book answers many questions for the student, teacher and practitioner as to the origins, properties and practical applications of radioactivity in fields such as medicine, biological and environmental research, industry, safe nuclear power free of greenhouse gases and nuclear fusion. Ratings and Reviews of Previous Editions: CHOICE Magazine, July 2008: "This work provides an overview of the many interesting aspects of the science of radioactive decays, including in-depth chapters that offer reminiscences on the history and important personalities of the field...This book can be useful as supplemental reading or as a reference when developing course material for nuclear physics, nuclear engineering, or health physics lectures. Special attention has been given to a chapter on the role radioactivity plays in everyday life applications...Generally the book is well produced and will be a valuable resource...Many lectures can be lightened up by including material from this work. Summing up: RECOMMENDED. Upper division undergraduates through professionals; technical program students." U. Greife, Colorado School of Mines, USA "I found the biographical accounts of the various stalwarts of Physics inspirational. Most of them, if not all, had to overcome economic hardships or p[ersonal tragedies or had to do their groundbreaking work in the face of tyranny and war. The biographies also highlighted the high standards of moral convictions that the scientists had as they realized the grave implications of some of their work and the potential threats to humanity. This ought to inspire and motivate young men and women aspiring to be physicists. Even people who have been in the field for a while should find your book re-energizing. It certainly had that effect on me." -- Dr. Ramkumar Venkataraman, Canberra Industries, Inc., Meriden, CT, USA Winner of an Honorable Mention in the 2017 PROSE Awards in the category of Chemistry and Physics (https://proseawards.com/winners/2017-award-winners/ )

Synchrotron radiation is the name given to the radiation which occurs when charged particles are accelerated in a curved path or orbit. Classically, any charged particle which moves in a curved path or is accelerated in a straight-line path will emit electromagnetic radiation. Various names are given to this radiation in different contexts. Thus circular particle accelerators are called synchrotrons, this is where charged particles are accelerated to very high speeds and the radiation is referred to as synchrotron radiation.Suitable for a summer short course or one term lecture series this text introduces the subject, starting with some historical background then covering basic concepts such as flux, intensity, brilliance, emittance and Liouville's theorem. The book then covers the properties of synchrotron radiation, insertion devices, beamlines and monochromators before finishing with an introduction to free electron lasers and an overview of the most common techniques and applications of this technology.

This book is an introduction to the concept of symmetries in electromagnetism and explicit symmetry breaking. It begins with a brief background on the origin of the concept of symmetry and its meaning in fields such as architecture, mathematics and physics. Despite the extensive developments of symmetry in these fields, it has yet to be applied to the context of classical electromagnetism and related engineering applications. This book unravels the beauty and excitement of this area to scientists and engineers.
