John Shanahan, civil engineer, President of Environmentalists for Nuclear - USA: Who does not like plants, animals, people and nature? Where do we come from? Through all the processes of life, we come mostly from carbon dioxide in the air and rain water. Here are some answers, some photos of life and some questions about the future.

Robert Bryce is author of “Smaller Faster Lighter Denser Cheaper,” and many other books and articles about energy. Coal is denser, contains more energy, and is easier to handle than wood. Oil takes up half as much space as coal and can be transported easily and cheaply by pipeline. Natural gas can be used for many of the same purposes as oil, including terrestrial transportation, power generation, and space heating, but is now cheaper than oil (on a Btu basis). Gas emits about half as much carbon dioxide as coal and creates far fewer air pollutants than either oil or coal. Electricity (which of course must be manufactured from coal, natural gas, oil, uranium or thorium) is extremely flexible, is easily transported via wires, and can be switched on or off with the flick of a switch. Using carbon-based fuels like coal, oil, and natural gas to create cleaner, more ordered forms of energy like electricity provides opportunities to use evermore sophisticated tools, with computers and lasers being prime examples of this trend.

The nature and risks of nuclear radiation are widely misunderstood from the most advanced society to the least sophisticated societies. Many view nuclear radiation as they view ghosts and spirits. People who fear what they regard as ominous phenomena generally have difficulty explaining why. This facilitates the promotion by scaremongers of irrational fear. During the era of nuclear weapons testing, radiation fear mushroomed. It endures despite the fact that, for over half a century, 450 water-moderated nuclear power plants delivered millions of terawatt hours of electricity without a single radiation fatality.

Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: This article was presented at the ANS - HPS Joint Topical Conference on LNT, Linear No-Threshold Model and Cumulative Dose. It is a straightforward proof that radiation dose is not a cumulative measurement.
