Hace 2 días · t. e. Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
Hace 1 día · Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes ), combine to form one or more different atomic nuclei and subatomic particles ( neutrons or protons ). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.

Hace 6 días · Since 238 U has a much longer half-life than the lighter isotopes, DU is about 40% less radioactive than natural uranium. Most of the alpha radiation comes from 238 U and 234 U whereas beta radiation comes from 234 Th and 234 Pa that are formed within a few weeks.
Hace 5 días · We call unstable atoms radioactive, because they produce nuclear radiation when they decay. For example, radon, uranium, and plutonium are all naturally radioactive. There are three types of nuclear decay, or three ways through which a nucleus can change: alpha decay (𝛼), beta decay (𝛽), gamma decay (𝛾).
Hace 2 días · Introduce radioactive decay Now that students understand isotopes, guide them towards radioactive decay – the process of an unstable nucleus losing energy through emitting radiation. Familiarize students with key terms such as alpha, beta, and gamma radiation and help them comprehend half-life by demonstrating exponential decay graphs or using simulations.
Hace 5 días · Radioactive Isotopes are the atoms with an unstable nucleus regain stability by emitting radiation, which contains extra particles and energy. The process of radiation decay is known as radioactive decay. Each radioisotope's radioactive decay process is distinct, and its half-life is used to measure it.
