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 Enter the nuclear equation for the positron emission of 2211Na (sodium-22). Express your answer as a nuclear reaction. Enter three nuclear equations to represent the nuclear decay sequence that 22/11 Na undergoes beta-plus decay. Determine the resulting nucleus.

We report on measurements of relative beta-decay rates of Na-22, Cl-36, Co-60, Sr-90, Cs-137 monitored for more than one year. The radioactive samples are mounted in an automated sample changer that sequentially positions the five samples in turn, with high spatial precision, in front of each of four Geiger–Müller tubes.

electron capture. Electron capture is usually classified as a type of beta decay and involves an orbital electron being absorbed by a nucleus, effectively converting a proton into a neutron. E.g., K-40, Mn-54, and Fe-55 radionuclides decay by this process. See Fig 3.

Beta Decay. There are actually three types of beta decay. The first discovered was “ordinary” beta decay and is called β − decay or electron emission. The symbol β − represents an electron emitted in nuclear beta decay. Cobalt-60 is a nuclide that β − decays in the following manner: 60 Co → 60 Ni + β − + neutrino.
