Hey, For my first post here, I had a question about the gamma spectrum of Na-22. I measured the gamma spectrum of Na-22 with a Ge-spectrometer. Using Genie-2000 software I saw two peaks in the spectrum, 1274 keV (peaksurface 3981±1,74%) and 511 keV (peaksurface 25494±0,68%). (Horizontal

The equation for the negative beta decay of 22Na is: 1122Na --> 1022Ne + 10e where 10e represents a positive beta particle or positron.

Na 22 beta decay

The shortest-lived is 18. Na, with a half-life of 1.3 (4) × 10−21 seconds. Answer to 4) Sodium-22 (Na-22) is radioactive and decays by beta plus decay mode. The half-life is 2.603 years. (a) Calculate the • A beta particle with energy of 795 keV can penetrate to a depth of the lens of the eye (0.3 cm or 300 mg/cm. 2).

In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is

In Beta plus (β+) decay a proton transforms into a neutron and a positron. 25 25 + Na ---> Ne + e + E In nuclear physics, beta decay is a type of particle decay in which beta radiation is emitted . It owes its name to the classification made by Emest Rutherford in 1899 of the radioactive emissions in alpha and beta, according to the capacity of penetration in the objects and the capacity of ionization.

The nuclei were produced via the Na 23 (t, p)Na 25 and Al 27 (t, p)Al 29 reactions, respectively, at the incident triton energy of 2.7 MeV. 11 Na + e + + ν e. Because positron emission decreases proton number relative to neutron number, positron decay happens typically in large "proton-rich" radionuclides. Positron decay results in nuclear transmutation, changing an atom of one chemical element into an atom of an element with an atomic number that is less by one unit. During beta-plus decay, a proton in an atom's nucleus turns into a neutron, a positron and a neutrino.
