A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and nuclear forces. [1] Radioactive decay is a random process at the level of ...
Induced radioactivity, also called artificial radioactivity or man-made radioactivity, is the process of using radiation to make a previously stable material radioactive. [1] The husband-and-wife team of Irène Joliot-Curie and Frédéric Joliot-Curie discovered induced radioactivity in 1934, and they shared the 1935 Nobel Prize in Chemistry ...
Many sites are contaminated or warehouse decades of radioactive waste, while some perform critical energy and defense research and manufacturing that could be crippled by increasingly ...
Particle radiation from radioactive material or cosmic rays almost invariably carries enough energy to be ionizing. Most ionizing radiation originates from radioactive materials and space (cosmic rays), and as such is naturally present in the environment, since most rocks and soil have small concentrations of radioactive materials.
What to know about Piney Point, a former industrial site that threatened the health of Tampa Bay.
The operator of the Fukushima Daiichi nuclear power plant said the discharge of the second batch of treated radioactive wastewater into the sea ended as planned on Monday, and International Atomic ...
Decay heat as fraction of full power for a reactor SCRAMed from full power at time 0, using two different correlations. In a typical nuclear fission reaction, 187 MeV of energy are released instantaneously in the form of kinetic energy from the fission products, kinetic energy from the fission neutrons, instantaneous gamma rays, or gamma rays from the capture of neutrons.

Plans call for treating radioactive waste in 2025, making the melters the largest in the world doing that work. DOE’s Savannah River, S.C., site began operating a facility to vitrify less ...
