off the molecules, thus creating ions. Non-ionizing radiation, such as infrared (thermal) radiation, is different because it does not create ions when it interacts with matter, but dissipates energy. The three main types of ionizing radiation are alpha particles, beta particles, andgamma rays....
Radioactive waste, by definition, is unneeded material that contains unstable elements that decay by emitting alpha, beta or gamma emissions. This article describes the sources of this waste, the types of waste that are of concern and the amounts estimated to be present in the US. 机译:...
The ionizing radiation, which can cause cellular damage in humans and other species, includes types called alpha, beta, and gamma radiation. These different types of radiation have vastly different penetrating power through matter. With regard to human health impacts, alpha radiation is of most ...
By definition, practically everything that does not belong to one of the three categories discussed above is considered low-level waste. This name is misleading because some wastes, though low in transuranic content, may contain very high beta and gamma activity. The current method of low-level...
This specification presents methods of containing/absorbing alpha, beta, gamma, X-ray, and neutron radiation using Fullerene molecules employing the resonant relativistic absorption phenomena based on a frequency dependant Doppler effect. Radioactive atoms, ions, and molecules (Xrad) are encapsulated in ...
emissions into three types of beams. For lack of better terms, the rays were given the alphabetic names alpha, beta and gamma, still in use today. It was obvious from the direction of electromagnetic forces that alpha rays carried a positive charge, beta rays carried a negative charge, and...
Radioactive emissions can take several forms, primarily alpha particles, beta particles, and gamma rays. Each type of emission has distinct properties and effects on the atom from which it originates: Alpha Particlesare helium nuclei, consisting of two protons and two neutrons. When an atom emits...

The S-9-EU provides a wide range of alpha, beta and gamma emissions making it a popular choice for nuclear science instruction The set contains two beta emitters, two beta/gamma emitters and one alpha source for in-depth studies of radiation. Includes (1) Po-210 0.1uCi (3.7 kBq) (1...
As used in this disclosure and the following claims, the “type of expected radioactive emission” associated with an isotope in the waste material to be treated refers to the particular type of both primary and secondary emission (alpha, beta, gamma, or neutron) characteristic of the isotope ...
