Download or read book The Radioactive Boy Scout written by Ken Silverstein and published by Villard. This book was released on 2005-01-11 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing up in suburban Detroit, David Hahn was fascinated by science. While he was 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 model nuclear reactor in his backyard garden shed. Posing as a physics professor, David solicited information on reactor design from the U.S. government and from industry experts. Following blueprints he found in an outdated physics textbook, David cobbled together a crude device that threw off toxic levels of radiation. His wholly unsupervised project finally sparked an environmental emergency that put his town’s forty thousand suburbanites at risk. The EPA ended up burying his lab at a radioactive dumpsite in Utah. This offbeat account of ambition and, ultimately, hubris has the narrative energy of a first-rate thriller.

Welcome to the path of enhanced fire safety and knowledge. Let’s begin exploring the world of fire detection systems! Ionization smoke detectors are a type of smoke detector that use ionization technology to detect the presence of smoke in the air. Here’s a detailed overview: How Ionization Smoke Detectors Work Radioactive Material: Ionization smoke detectors contain a small amount of radioactive material, typically americium-241. This radioactive material ionizes the air in a small chamber within the detector. Ionization Process: The americium-241 emits alpha particles, which collide with air molecules, creating ions (charged particles). This process generates a small, steady electrical current within the chamber as the ions move between two charged plates. Disruption by Smoke: When smoke enters the ionization chamber, it attaches to the ions, disrupting the flow of electrical current. The reduction in current flow is detected by the circuitry within the smoke detector. Alarm Activation: The decrease in current flow triggers the alarm, alerting occupants to the presence of smoke and potential fire. Characteristics and Advantages Sensitivity to Fast-Flaming Fires: Ionization smoke detectors are particularly responsive to fast-flaming fires that produce small, invisible combustion particles. These fires often spread rapidly and can be detected quickly by ionization detectors. Cost-Effective: Generally, ionization smoke detectors are less expensive than photoelectric smoke detectors. Widespread Use: They are widely used and can be found in many homes and commercial buildings. Limitations False Alarms: Ionization smoke detectors are more prone to false alarms caused by cooking fumes or steam. Less Effective for Smoldering Fires: They are less sensitive to slow, smoldering fires that produce larger smoke particles. For these types of fires, photoelectric smoke detectors are more effective. Radioactive Material: Although the amount of radioactive material used is very small and poses minimal health risk, some people may prefer to avoid products containing radioactive substances. Installation and Maintenance Placement: Install ionization smoke detectors on every level of the home, inside each bedroom, and outside sleeping areas. They should be placed on the ceiling or high on the wall. Regular Testing: Test the detectors monthly to ensure they are working properly. Most units have a test button that can be pressed to check the alarm. Battery Replacement: Replace the batteries at least once a year or whenever the low-battery warning sounds. Some newer models come with long-life batteries that last up to 10 years. Replacement of Units: Replace the entire smoke detector unit every 8-10 years, as sensors and electronic components degrade over time. Combination Detectors Many modern smoke detectors combine both ionization and photoelectric sensors to provide comprehensive protection against both fast-flaming and smoldering fires. These dual-sensor detectors can offer enhanced safety and help reduce the likelihood of false alarms. Summary Ionization smoke detectors are an effective and affordable solution for detecting fast-flaming fires. However, for optimal fire protection, especially in residential settings, it’s often recommended to use a combination of ionization and photoelectric smoke detectors or dual-sensor units. Regular maintenance and proper placement are key to ensuring these devices function correctly and provide early warning in the event of a fire.

Available in PDF, EPUB and Kindle. Book excerpt: Freakonomics was a worldwide sensation, selling more than four million copies. Now Steven D. Levitt and Stephen J. Dubner return with SuperFreakonomics, and fans and newcomers alike will find that this freakquel is even bolder, funnier, and more surprising than the first. SuperFreakonomics challenges the way we think all over again, with such questions as: How is a street prostitute like a department-store Santa? What's the best way to catch a terrorist? What do hurricanes, heart attacks, and highway deaths have in common? Are people hardwired for altruism or selfishness? Can eating kangaroo save the planet? Levitt and Dubner mix smart thinking and great storytelling like no one else, whether investigating a solution to global warming or explaining why the price of oral sex has fallen so drastically.

Book excerpt: The God We Can Know is a 7-week study designed for the entire congregation to explore the "I Am" sayings of Jesus found in the Gospel of John. Perfect for Lent or any time of year, this series will help you find and form an answer to the most essential question in the Christian faith, "Who do you say I am?" One by one, Jesus' statements grab our imagination, reveal more about his identity and purpose, and connect us to the God of Moses, who spoke the first "I Am." These significant yet ordinary images (bread, light, shepherd, vine, and more) give us insightful ways to experience Jesus and point us to a God who wants to be known. The DVD, filmed on location in the Holy Land, allows you to travel with Rob Fuquay and actually see the places where Jesus stood when he disclosed his true identity, and in what context he spoke each "I Am." The book, DVD/study guide combo, and online support work together to provide one of the most meaningful, transforming initiatives your church can provide for the entire congregation. Weekly themes include: Introduction to "I Am"—Knowing God I Am the Bread of Life—Knowing God's Satisfaction I Am the Light of the World—Knowing God's Guidance I Am the Good Shepherd—Knowing God's Care I Am the True Vine—Knowing God's Power I Am the Way, the Truth, and the Life—Knowing God's Way I Am the Resurrection and the Life—Knowing God's Possibilities
