It is clear that artifacts have the power to provoke thought, inspire action and arouse passions. There is evidence of this in the ever-increasing number of museums as well as in the ability of those museums to stimulate controversy through exhibits. As a consequence, much has been written analyzing the interaction between objects and museum visitors. Less well recognized, or understood, is the value of objects for historical research. In this series of books we propose to show by example how artifacts can be employed in the study of the history of science and technology in ways ranging from motivating a line of research to providing hard evidence in the solution of an otherwise insoluble problem. The first volume focused on medicine; in this, the second volume, the topic our authors address is electronics. As readers will discover, there is considerable scope in the range of topics and in the range of uses of artifacts. There is also a section that suggests to readers what kind of questions they might consider when they visit electrical exhibits, and where those exhibits are to be found. This series is sponsored by the Deutsches Museum in Munich, the Science Museum in London, and the Smithsonian Institution in Washington, with help from professional historians in other museums and elsewhere.
Have you ever wondered about the safety or dangers of: Cell Phones Smartphone Addiction Cell Tower Radiation WiFi, Bluetooth High-Voltage Power Lines Smart Devices 5G Mobile Networks Baby Monitors Cordless Phone Bases Microwave Oven Radiation . . . Just to name a few of the topics in "EXPOSED: The Electronic Sickening of America and How to Protect Yourself." There's a hidden danger pulsating in the airways and buzzing behind the walls of millions of American homes, schools, and businesses. Our families, co-workers, even our pets, are exposed to electromagnetic radiation (EMR) almost continually, 24/7. Few people want to address this topic because they don't know what to do. They are frustrated and overwhelmed by the scattered and conflicting information that's out there. And they fear that they will have to give up their electronic necessities. I felt that way as well--until I learned that the great news is that you CAN take control of your exposure to harmful electromagnetic radiation and learn how to use your electronic devices more safely. First, some background: A disturbing correlation has been discovered between electro-pollution and a host of diseases and disorders. These include cancer, neurological diseases, respiratory diseases, behavioral disorders, chronic fatigue, ADHD, insomnia, depression, headaches, muscle/joint pain, chronic inflammation, and many more. The report "BioInitiative 2012," collates research from around the world on the bio-effects and health hazards of electromagnetic fields and electromagnetic radition: from wires and wireless technologies. It represents more than 3,800 scientific, peer-reviewed studies done by PhDs and MDs on the potential health effects of prolonged exposure to electromagnetic radiation. And the research continues to grow. Electromagnetic radiation is the tobacco of the Digital Age. And, like tobacco, it can kill you. The widespread rollout of 5G will only exacerbate the problem. We don't really know how this is all going to turn out. We are all "guinea pigs" in a huge, highly lucrative, disorganized experiment. The telecommunications industry doesn't have to win the scientific argument about safety; it only has to keep the argument going. We need to research the research and follow the dollars. Most people don't have the time to do that. That's why I wrote this book. To put you at ease, I want to say that I am not anti-technology. I use it on a daily basis. I have a smartphone and computer, and use social media. This book is about how to use your electronic devices more safely. It is about how to guard yourself and the people you love against the unintended consequences of the digital age. This book has been written to be accessible to the person who has little or no technical background in electronics or physics. It has many practical solutions that can be accomplished by just about anyone in one minute, and often without cost. EXPOSED gives you the "back story" and provides information so you can discern the facts from fiction regarding the safety of wireless technology and dirty electricity. Most importantly, this book provides solutions. There are good, better, and best ways to use technology in order to minimize your exposure to harmful radiation. Read it. Do it. Share it.
The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients. High Tech Trash is a wake-up call to the importance of the e-waste issue and the health hazards involved. Americans alone own more than two billion pieces of high tech electronics and discard five to seven million tons each year. As a result, electronic waste already makes up more than two-thirds of the heavy metals and 40 percent of the lead found in our landfills. But the problem goes far beyond American shores, most tragically to the cities in China and India where shiploads of discarded electronics arrive daily. There, they are "recycled"-picked apart by hand, exposing thousands of workers and community residents to toxics. As Grossman notes, "This is a story in which we all play a part, whether we know it or not. If you sit at a desk in an office, talk to friends on your cell phone, watch television, listen to music on headphones, are a child in Guangdong, or a native of the Arctic, you are part of this story." The answers lie in changing how we design, manufacture, and dispose of high tech electronics. Europe has led the way in regulating materials used in electronic devices and in e-waste recycling. But in the United States many have yet to recognize the persistent human health and environmental effects of the toxics in high tech devices. If Silent Spring brought national attention to the dangers of DDT and other pesticides, High Tech Trash could do the same for a new generation of technology's products.
