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 ...
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 ...
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...
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...
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...
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....
Both these radionuclides decay by beta emissions. In the case of 60Co two high-energy gamma rays are emitted in cascade in >99% of the transitions. The radionuclide 137Cs is actually a pure beta-emitter and the gamma ray associated with the decay of this radionuclide is actually due to ...

“primary radioactive emission” comprises the emission or emissions directly from the radioactive decay of an isotope. For most radioactive isotopes, the primary radioactive emissions will include either an alpha or beta emission at a characteristic energy level and a gamma emission at a ...
