Learn more about this topic: Alpha Particles | Definition, Composition & Symbol from Chapter 22 / Lesson 2 53K Understand what an alpha particle is, and explore how alpha particles are produced along with examples. Learn about the symbol and composition of an alpha particle. ...
Because of this, these elements are also called alpha emitters. An alpha particle is commonly represented by the symbol α, the Greek letter alpha for which the particle is named. It was the first type of nuclear radiation to be discovered, before beta particles and gamma rays. But because ...
Alpha Particles The various kinds of radioactive decay are given the first three letters of the Greek alphabet. Thus alpha radiation emits a particle often represented by a lowercase version of this letter, α. It would be unconventional, however, to write "α-radiation." This kind of ...
Alpha particles cause extensive ionization in matter. If the particles are allowed to pass into a gas, the electrons released by the ionization can be collected on a positive electrode to produce a pulse or current. Ionization chambers and proportional counters are instruments of this kind, which...
In MCNP6, the energy of alpha particles is defined by specifying the source energy spectrum in the input file. This can be done using the SDEF card to set the initial conditions of the particle source, including the energy distribution. What units are used for alpha particle energy in MCNP...
The outer zone population of trapped particles and protons was measured off the equator [B/B0 = 1.32.3] in the L interval 2 ¤ L ¤ 4 during 1969. The particle spectra are best represented by a power law with spectral indices between 2.4 and 4.0 over the energy range 0.85 ¤ E ¤ ...
The liquid-drop model of nuclei, which can be considered as a simple version of a local density approach, reflects important properties of nuclear structure, for example the famous Bethe-Weizsäcker mass formula. Other properties such as the occurrence of magic numbers are explained by the shel...
respectively. Cells exposed to vesiculated α-TOS underwent apoptosis earlier probably due to enhanced interaction of cancer cells with particles formed by α-TOS vesiculation[14]. α-Tocopherylmaleateester (α-TOM) was found to exhibit far more efficient apoptogenic activity than its α...

Alpha particles are extremely effective in destroying cancer cells in comparison to standard photon-based techniques, however, their limited range in tissue represent a strong limitation for their application in clinical setting. A requirement to employ particle based radiotherapy is great precision in ta...
