A great project book for things that go 'Boom' !
by William
Gurstelle
| A great 'boy's book'-
boys (and girls with similar interests) from 9 to 90 will get a bang out
of these projects. The author presents enough safety information to be
reasonable, and mixes in scientific explanations, a bit of math, and
interesting anecdotes that take us back into the history of ballistics.
But most of all, he presents details plans and parts lists (including
sources for hard to find parts) to build things that shoot up into the
air, things that go "BOOM," and other cool stuff like fire
kites.
Many of the projects described here have been documented elsewhere, but most other sources of information have little to say about safety, science, or history. Using this book as a starting point could lead one to develop a truly interesting ballistic arsenal indeed!! Just from skimming through it you can tell that a lot of thought and precaution went into it's construction. Parents may be scared seeing a book like this in the hands of their child, but don't be frightened. Most of the projects in here are pretty innocuous and safety is paramount. The book and author STRESS proper precautions and advise safety gear for any dangerous experiments. If you have a kid who has been playing with fire, been showing an interest in explosives or such, then buy them this book and do these projects with them! It will give kids a productive, educational and supervised outlet for these curiosities and fascinations and will give you a chance to teach them a bit about physics and further bond with them. Some young pyros grow into arsonists, others grow into firemen and physicists... you make the choice! Instead of punishing them and trying to curb their interest in such things, channel this energy into something positive. Before we had homeland security
to worry about, this might have been a good source book for a science
fair. If you're in touch with your inner Goddard, von Braun, or just
love the idea of a tennis ball mortar ... then this is the book for you! 169

Radium Girls ![]()
The most famous
case of radiation poisoning.
by Claudia Clark
|
The story of the
radium watch-dial painters is a classic case in the history of
occupational disease. Attracted by easy work and high wages, these young
women painted the luminous numbers on wristwatches that, designed for
soldiers involved in the trench warfare of World War I, became a
consumer fad in the 1920s. The women were taught to sharpen the tips of
their paintbrushes between their lips and, as a result, they absorbed
substantial quantities of radium. Their tragic illnesses and deaths led
to crucial discoveries in radiobiology and contributed to the
establishment of standards for the level of exposure to radiation in the
workplace.
The basic details of this episode are well known, but the story has only now received the detailed historical analysis it deserves. In Radium Girls Claudia Clark focuses on the experiences of the painters. She integrates startling anecdotes with sophisticated analyses to explore the politics of occupational disease. For example, Clark describes the excitement of the women who worked on these "sensational" products: told that radium would "put a glow in [their] cheeks," they painted their clothing, fingernails, and even their teeth, "for a smile that glowed in the dark." How could this have happened? As Clark reminds us, these women worked at a time before the bombing of Hiroshima, when radiation was seen as the key to the future. Though some researchers had documented the dangers of radium, it was hailed as a panacea and sold for a variety of medicinal purposes. The deposition of radium in workers' bones was even seen as beneficial: their bodies were bathed in the healing power of radiation. Clark traces how this excitement turned into fear and "furious frustration." When workers began to suffer from anemia, fractures, and necrosis of the jaw, some of them, as well as their physicians and dentists, suggested that there was a connection to the radium paint. The watch-dial companies rejected these claims. Government regulators concluded that the existing evidence did not warrant further investigation. Recognition of radium poisoning took years of effort by the women and workers' advocates. This narrative is rich in tragedy and scandal: researchers accepted companies' requests that they not release their damning data; a dentist offered his testimony to the highest bidder. Although settlements did provide some financial compensation, the companies neither admitted guilt nor submitted to formal regulation. Although the government was slow to intervene on behalf of the dial painters, it took rapid action to prevent any injuries from radium medications; it "acted with far greater alacrity to help consumers than to assist workers." The most valuable contribution of Radium Girls lies in its ability to explode myths about the nature of scientific discovery. As Clark shows, the recognition of radium poisoning was not an event, a flash of medical insight. Instead, it was a political process, negotiated by labor, management, government, and medicine. Clark also explores a host of other important issues, providing helpful histories of industrial disease, workers' compensation, women's reform movements, and radiation medicine. Overall, Radium Girls is an important book for anyone interested in the history of radiation. It captures the often neglected experiences and contributions of the painters. Most important, it powerfully reminds us that it is not enough to take precautions only against known toxins. Instead, we must struggle to anticipate new risks in our changing industrial and social environments. 298

How To Photograph ![]()
an Atomic Bomb
Amazing
images and history of the Atomic Bomb
by Peter Kuran
|
Peter Kuran has been fascinated with the Atomic
Bomb and its photography. As he writes: "It wasn't until 1945 that
the sciences of photography would cross paths with the sciences of the
atom. For the next 17 years, still and motion picture photography would
combine with atomic physics to create imagery the world may never
witness again first hand." These are extraordinary images for the reader and a great gift for anyone interested in the topic. 142 pages |
The
Chemistry of
Powder & Explosives
by Tenney L. Davis
| The
late Dr. Davis produced this book as part of the material used for
training his grad students in WWII about chemical engineering aspects of
explosives. However, the best part of the book is probably the section
on the history and development of explosives. This is a book for all kinds of people interested in explosive chemistry. This book is not only for the advanced explosive expert, it's also written for the beginner who's learning the basic characteristics of explosives . It provides us readers with a well rounded selection of high explosives, including dynamite, R.D.X, TNT, low explosives and propellants, primary explosives, etc. The book also contains a large chapter on Pyrotechnics, it's history, and a wide variety of firework formulas & their manufacturing technique. 512 pages |
The
Radioactive Boy Scout
by Ken Silverstein
| Growing
up in suburban Detroit, David Hahn was fascinated by science, and his
basement experiments—building homemade fireworks, brewing moonshine,
and concocting his own self-tanning lotion—were more ambitious than
those of other boys. While working on his Atomic Energy badge for the
Boy Scouts, David's obsessive attention turned to nuclear energy.
Throwing caution to the wind, he plunged into a new project: building a
nuclear breeder reactor in his backyard garden shed. In The Radioactive Boy Scout, veteran journalist Ken Silverstein recreates the months of David's nuclear quest. Posing as a physics professor, David solicited information on reactor design from the U.S. government and from industry experts. (Ironically, the Nuclear Regulatory Commission was his number one source of information.) Scavenging antiques stores and junkyards for old-fashioned smoke detectors and gas lanterns (both of which contain small amounts of radioactive material) and following blueprints he found in an outdated physics textbook, David cobbled together a crude device. His unsanctioned and wholly unsupervised project finally sparked an environmental catastrophe that caused the EPA to shut down his lab and bury it at a radioactive dumpsite in Utah. 209 pages |
The Plutonium Files
by Eileen Welsome
| From
April 1945 to July 1947, 18 men, women, and children were injected with
plutonium by doctors working with the Manhattan Project. None of the
subjects was told what was being done, and none gave informed consent.
They were chosen because the doctors believed them to be mortally ill,
although many lived for years, even decades, with the plutonium working
its damage in their bodies.
The experiments were covered up for 40 years: When they became public, the government apologized but not a single doctor or hospital was publicly blamed. The plutonium injections ended after 27 months, having achieved little. But other experiments, for the Manhattan Project and the Atomic Energy Commission (AEC), continued into the 1970s. In Nashville, scientists at Vanderbilt University gave pregnant women radioactive cocktails. Prisoners in Oregon and Washington had their testicles radiated with neutrons. At the University of Cincinnati, nearly 200 patients were irradiated over a 15-year period. In Massachusetts, 74 boys at a Dickensian state school for unwanted or homeless boys were fed oatmeal laced with radioactive iron or calcium. The University of Chicago, one of the three sites for the plutonium injections, also fed solutions of strontium and cesium to 102 subjects with the assistance of Argonne National Laboratory. Again, no one told the victims what was going on, nor did anyone ask their consent. This is a horrifying story and it is told with quiet rage by Eileen Welsome, a reporter for the Albuquerque Tribune who won a Pulitzer Prize in 1994 for her reporting on the plutonium experiments. News of these and other experiments had leaked out earlier, but they received little public attention. Welsome's achievement was to pierce the closed files and classified records that were part of the medical cover-up of the experiments. It is not possible to read The Plutonium Files without mounting fury, as Welsome tells of the violation of human bodies and spirits by scientists in whom this nation places its trust. Her book is a powerful indictment of an important part of the Manhattan Project and a warning of the evil that supposedly high-minded people can do when convinced of their own superiority and devoted to a goal that blinds them to simple humanity. There is documentary evidence that Robert Oppenheimer and other Manhattan Project scientists approved the experiments (although Welsome found no signs that Gen. Leslie Groves, who told Congress in 1945 that radiation sickness is "a pleasant way to die," ever knew about them.) The government covered up the plutonium experiments until 1993 when then-Energy Secretary Hazel O'Leary, spurred by Welsome's stories, reversed this policy. President Bill Clinton then ordered federal agencies to open any records dealing with the plutonium experiments or any other human radiation experiments. The resulting investigation, undertaken by the president's Advisory Committee on Human Radiation Experiments, turned up much of the information on other experiments that is included in this book. So was the very first plutonium recipient, a construction worker named Ebb Cade, who was injured in a traffic accident on his way to work at Oak Ridge and ended up in the army hospital there. Scientists had decided to begin the plutonium experiments and Cade--there is no other way to put it--happened to be handy. A month after Cade was injected in 1945, Wright Langham, a Los Alamos chemist who was a driving force behind the experiments, told a meeting of Manhattan Project doctors in Chicago that "the subject was an elderly male whose age and general health was such that there is little or no possibility that the injection can have any effect on the normal course of his life." Cade, in fact, was 55 and, apart from partial blindness caused by a cataract, reasonably healthy. He died eight years later of a heart attack. The third subject, a house painter named Albert Stevens, was chosen to be injected at the University of California Hospital in San Francisco because he had terminal cancer. But the diagnosis was wrong and Stevens lived another 21 years. For the next two decades, scientists collected Stevens's urine and stool samples to check the amount of plutonium in his system. He knew he was part of an experiment, but assumed it was part of his treatment for his arrested cancer. Incredibly, Stevens lived out his life unaware that he did not have cancer and had never had it. Welsome says that even the Rochester scientists called their program "a production line." Unknowing patients were given an average of five micrograms of plutonium, which was five times the safe limit set by Manhattan Project scientists. Eleven patients were injected at Rochester and there probably would have been more had it not been for inconveniences like Christmas. "No one seems to want to be in the hospital on that particular day," Bassett groused. "I will do what I can, however, to keep the production line going." The plundering of body parts of radiation victims reached ghoulish proportions. Cecil Kelley, who was killed in an accident at Los Alamos, was not so much buried as distributed. Bits of his corpse went to the army, to Oak Ridge, and to other researchers around the nation. His brain was shipped out in a wide-mouthed mayonnaise jar. What was left was eventually given a military burial by the government, which also promised to pay for his children's college education. The promise was never kept. The committee convened by President Clinton eventually issued a controversial 1995 report that blamed everyone--and, hence, no one. It found that bad things were done, but refused to condemn those who did them. "Wrongs were committed," it said, "by very decent people who were in a position to know that a specific aspect of their interactions with others should be improved." In a sense, as Welsome notes, the verdict on the plutonium experiments was handed down 2,500 years ago by Hippocrates--"I will give no deadly medicine to anyone if asked"--and 52 years ago by James McHaney, the chief prosecutor at the Nuremberg trials: "It is the most fundamental tenet of medical ethics and human decency that the subjects volunteer for the experiment after being informed of its nature and hazards. This is the clear dividing line between the criminal and what may be non-criminal. If the experimental subjects cannot be said to have volunteered, then the inquiry need proceed no further." 592 pages |
