Strontium-90 (^90Sr) is a radioactive isotope of strontium, which is a chemical element with the symbol Sr and atomic number 38. It is produced primarily as a byproduct of nuclear fission in reactors and during atomic bomb explosions. Strontium-90 has a half-life of approximately 28.8 years, which means it takes this amount of time for half of a given amount of the isotope to decay.
Thorium-232 is a naturally occurring isotope of thorium, which is a heavy, radioactive element with the atomic number 90. It is one of the most stable isotopes of thorium and has a half-life of about 14.05 billion years, making it significantly long-lived compared to other radioactive isotopes.
Anthony L. Turkevich was a prominent American chemist known for his significant contributions to the field of chemistry, particularly in the study of colloids and nanomaterials. He is often recognized for his work in developing methods for producing and characterizing nanoparticles, as well as his research on the properties and applications of these materials. Turkevich is perhaps best known for the Turkevich method, a technique for the synthesis of gold nanoparticles, which is widely utilized in nanotechnology and materials science.
Fallout protection generally refers to measures and strategies designed to protect individuals and communities from the harmful effects of radioactive fallout, which can occur after a nuclear explosion or accident. Fallout consists of radioactive particles that are lifted into the atmosphere and then settle back to the ground, potentially contaminating soil, water, and air. ### Key Components of Fallout Protection: 1. **Sheltering**: Staying indoors in a sturdy building can be crucial as it provides a barrier against radioactive particles.
Nuclear energy in Germany has been a significant part of the country's energy landscape, though its role has evolved dramatically over the past few decades. Here are some key points to understand the situation: 1. **Historical Context**: Germany began employing nuclear energy in the 1960s, with the construction of its first commercial nuclear power plant. Over the years, nuclear energy became an important source of electricity, contributing about 30% of the country's energy needs at its peak.
Nuclear programs refer to various initiatives by countries to develop and utilize nuclear technology for different purposes, which can be broadly categorized into three main areas: 1. **Nuclear Energy Programs**: These programs focus on the generation of electricity using nuclear reactors. Nuclear power plants harness the energy released during nuclear fission (the splitting of atomic nuclei) to produce steam, which drives turbines to generate electricity.
The pro-nuclear movement advocates for the increased use of nuclear energy as a solution to various energy-related issues, especially in the context of climate change and the transition to sustainable energy sources. Supporters argue that nuclear energy is a low-carbon alternative to fossil fuels and can play a crucial role in reducing greenhouse gas emissions.
The Ford Nucleon was a concept car developed by the Ford Motor Company in the 1950s, specifically unveiled in 1958. It was notable for being designed around a nuclear power source, reflecting the era's fascination with nuclear technology and the potential for near limitless energy. The Nucleon was envisioned as a futuristic vehicle that could operate on a small nuclear reactor, providing significant range and power.
A nuclear exclusion clause is a provision commonly found in insurance policies, particularly in property and liability insurance, that excludes coverage for damages or losses resulting from nuclear incidents. This clause is designed to limit the insurer's liability in the event of a nuclear accident, explosion, or radiation exposure.
A modulated neutron initiator is a type of device used to produce neutrons, typically in nuclear weapons or nuclear reactors, by using a modulation technique to enhance the neutron output. These initiators play a crucial role in starting nuclear reactions by providing a burst of neutrons at precisely the right moment, ensuring that the chain reaction can be sustained effectively.
Pyroelectric fusion is a theoretically proposed phenomenon where fusion reactions occur due to the effects of a pyroelectric material. Pyroelectric materials generate an electric charge in response to temperature changes. In a pyroelectric fusion setup, it's hypothesized that the electric fields produced by these materials at varying temperatures could potentially create the conditions necessary for nuclear fusion, typically involving the fusion of hydrogen isotopes such as deuterium and tritium.
Marvin Adams is a prominent figure in the field of nuclear engineering and computational science. He is known for his work in the areas of nuclear security, simulation, and modeling, particularly as they relate to the safety and effectiveness of nuclear systems. His contributions often focus on the development of advanced computational methods and tools for analyzing and ensuring the reliability of nuclear technologies. In addition to his research, Adams has also played significant roles in academia, often holding positions at institutions involved in nuclear engineering and applied sciences.
Nuclear power stations, also known as nuclear power plants, are facilities that generate electricity through nuclear reactions, typically through the process of nuclear fission. In these plants, the nuclei of heavy atoms, such as uranium-235 or plutonium-239, are split into smaller parts when they absorb a neutron, releasing a significant amount of energy in the form of heat.
Nuclear test sites are designated locations where nuclear weapons are tested to evaluate their performance, effectiveness, and safety. These sites are typically established by countries that possess nuclear capabilities and include both above-ground and underground facilities. The tests can involve the detonation of nuclear devices to gather data on their explosive yield, blast effects, and other physical phenomena associated with nuclear explosions.
Nuclear fuel companies are organizations involved in the production, processing, and supply of nuclear fuel, which is primarily used in nuclear power plants to generate electricity. These companies typically engage in various activities across the nuclear fuel cycle, including: 1. **Uranium Mining**: Many nuclear fuel companies are involved in the extraction of uranium, the primary fuel used in most nuclear reactors.
Neutron poisons, also known as neutron absorbers or neutron capture materials, are substances that absorb neutrons and thus reduce the reactivity of a nuclear reactor. They are used to control the rate of fission reactions within the reactor core by capturing free neutrons that are necessary for sustaining the chain reaction. Common neutron poisons include: 1. **Boron**: Often used in the form of boric acid, boron is a well-known neutron absorber.
A radioactive source is a material that emits radiation as a result of the decay of unstable atomic nuclei. This decay process can include the emission of alpha particles, beta particles, gamma rays, or neutrons. Radioactive sources can be found in various forms, such as gases, liquids, and solids, and can be naturally occurring (like uranium or radon) or artificially produced (such as cesium-137 or cobalt-60).
Nuclear spacecraft propulsion refers to the use of nuclear reactions to generate thrust for space travel. This technology is considered for both deep-space missions and potential manned missions to other planets, such as Mars. There are several concepts and methods for nuclear propulsion, primarily divided into two categories: nuclear thermal propulsion (NTP) and nuclear electric propulsion (NEP). ### 1.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
